Stack:
* #17926 Implement at::has_internal_overlap helper function
* **#17927 Error out on in-place (unary) ops on tensors that have internal overlap**
On the way to #17935.
Works for CPU and CUDA on the following ops:
- abs_, acos_, asin_, atan_, ceil_, cos_, erf_, erfc_, exp_, expm1_
- floor_, log_, log10_, log1p_, log2_, round_, rsqrt_,
- sin_, sqrt_, tan_, tanh_, trunc_
This PR adds a check to see if the out/result tensor has internal
overlap. If it does, then we error out because the result **may** be
incorrect.
This is overly conservative; there are some cases where if the result is
the same as the input, the inplace operation is OK (such as floor_,
round_, and trunc_). However, the current code isn't organized in such a
way that this is easy to check, so enabling those will come in the future.

Summary:
This PR causes kthvalue to be consistent with sort
(i.e. treat NaN as larger than any number), so that
`a.kthvalue(n) == a.sort()[n - 1]`.
One drawback is that median with a NaN argument does not return NaN,
which is a deviation from NumPy.
Thank you, ngimel, for raising this.

Summary:
update:
1. global_reduce check for should_block_y_reduce first.
This avoids the enabling global_reduce without block_y_reduce. Leading to
accessing shared memory during global reduce without allocation.
2. updating block_y_reduce heuristics. Improves perf on tiny tensors
3. adding test case covering old cases where illegal memory access might occur
TensorIterator cuda launch configs update (#16224)
Update launch configs for TensorIterator gpu_reduce_kernel. Enable flexible
block dimension to improve efficiency for reduction cases with small fast
dimension.
Previously TensorIterator launches blocks with fixed 32x16 threads.
For cases like:
import torch
torch.randn(2**20, 4, device='cuda').sum(0)
The fixed launch config does handle coalesced memory access efficiently.
Updated launch configure enables flexible block dimension. Combining with
improved reduction scheme (using flexible vertical / horizontal reduction
instead of limited warp / block reduction in the old code), it ensures optimal
memory access pattern even with reduction on dimension with small stride.
Possible future improvements:
1. Precise dynamic shared memory allocation.
2. Using warp shuffle for vertical (block_y) reduction.

Summary:
see #15682
This is a quick fix by implementing the simpler solution as suggested by colesbury. As benchmark result shows, it slows down `Stream.query()` by ~20%, I would be happy to further pursue a more complex solution by implementing this in C++/ATen. But I would still vote for merge this quick fix first just to get rid of the bug sooner.

Followup PR of #14904, and the stretch goal of #12653.
Directly calculate coordinates in the original tensor using column index in the result tensor. Every GPU thread takes care of a column (two numbers) in the output tensor.
The implementation detects and handles precision loss during calculating the square root of a `int64_t` variable, and supports tensors with up to `row * column = 2 ^ 59` numbers.
Algorithm details are describe in [comments of TensorFactories.cu](23ddb6f58a/aten/src/ATen/native/cuda/TensorFactories.cu (L109-L255)).

Summary:
This is an optimized implementation that does the following:
1. created an empty Tensor of correct size.
2. fill the Tensor with correct values.
The following three designs to fill in the Tensor result in roughly the same performance. Hence, the 2nd option is taken for simpler code, and to return contiguous tensors.
1. Sequential: fill row coordinates first, then columns. This results in two for-loop and more arithmetic operations.
2. Interleaved: fill in index coordinates one by one, which jumps between the two output Tensor rows in every iteration.
3. Transpose: create a n X 2 Tensor, fill the Tensor sequentially, and then transpose it.

NOTE:
This implementation returns a 2D tensor, instead of a tuple of two tensors. It means that users will not be able to do the following:
```python
x = torch.ones(3, 3)
i = torch.tril_indices(3, 3)
x[i] # need to first convert the 2D tensor into a tuple of two 1D tensors.

The new error message now looks like (from Python):
RuntimeError: CUDA out of memory. Tried to allocate 16.00 GiB (GPU 0; 11.93 GiB total capacity; 4.00 GiB already allocated; 7.33 GiB free; 179.00 KiB cached)
Summary of terms:
"total capacity": total global memory on GPU
"already allocated": memory allocated by the program using the
caching allocator
"free": free memory as reported by the CUDA API
"cached": memory held by the allocator but not used by the program
The "allocated" amount does not include memory allocated outside
of the caching allocator, such as memory allocated by other programs
or memory held by the driver.
The sum of "allocated" + "free" + "cached" may be less than the
total capacity due to memory held by the driver and usage by other
programs.
Note that at this point cuda_malloc_retry has already returned all
possible "cached" memory to the driver. The only remaining "cached"
memory is split from a larger block that is partially in-use.
```
This also fixes an issue where on out-of-memory could cause an unrelated subsequent CUDA kernel launch to fail because `cudaGetLastError()` was not cleared.

Summary:
In `broadcast_coalesced`, since multiple variables can be "views" of a big flattened tensor, they can share the same version counter. However, this base flat tensor is not exposed and they don't share any memory locations, so this is not necessary. Furthermore, it can cause problems, e.g., when two buffers are broadcast together in `DataParallel` and one of them is modified in-place during `forward` but the other is needed in backward, autograd engine will complain.

name of this file is so common that can easily conflict with other dependencies
if they happen to have another common.py in the base module. Rename the file to

The old behavior is that we return `0` after we run out of postive categories. Now we raise an error based on discussion in the issue thread.
- Add testcase for cpu & cuda case, in cuda case `n_samples=1` is a simple special case, so we test against `n_sample=2` instead.

Summary:
The gpu_unary_kernel function was not handling arrays that
cannot use 32-bit indexing. This functions was only called directly
by CUDA division by a scalar. Other arithmetic operations go through
gpu_binary_kernel, which already properly handled large arrays.
This bug sometimes manifested as a crash and sometimes as an incorrect
answer.

fixed in moving `bernoulli_out` to ATen
+ https://github.com/pytorch/pytorch/issues/9917 : BUG torch.bernoulli(p.expand(shape)) is broken
fixed in moving all `bernoulli` ops in ATen to use the modern apply utils methods
+ https://github.com/pytorch/pytorch/issues/10357 : torch.bernoulli inconsistent gpu/cpu results
fixed by adding CUDA asserts
In order to use `curand_uniform4`, I made some changes to `CUDAApplyUtils.cuh`. Specifically, I introduced an optional template parameter `int step` to the `CUDA_tensor_applyN` methods, representing that we want to process `step` values at each time for each of the `N` tensors.
The calling convention for `step = 1` (default) isn't changed. But if `step > 1`, the given lambda `op` must take in `int n` as its first argument, representing the number of valid values, because there may not be full `step` values at the boundary. E.g., here is what the `bernoulli(self, p_tensor)` call look like:
```cpp
// The template argument `4` below indicates that we want to operate on four
// element at each time. See NOTE [ CUDA_tensor_applyN helpers ] for details.

Summary:
```
This adds TensorIterator, a helper class for computing element-wise
operations that's intended to replace the CPU and CUDA apply utils
functions.
CPU kernels are implemented as functions that operate on strided 1-d
tensors compared to CPUApplyUtils which operated individual elements. This
allows the kernels to handle vectorization, while TensorIterator handles
parallelization and non-coalesced dimensions.
GPU kernels continue to operate on elements, but the number of
specializations is reduced. The contiguous case remains the same. The
non-contiguous case uses a single (reduced) shape for all operands and
the fast integer division from THCIntegerDivider. To avoid extra
specializations for indexing with 64-bits, large operations are split
into smaller operations that can be indexed with 32-bits.
Major semantic changes:
- No more s_add, s_mul, s_div, or s_sub. Broadcasting is handled by
TensorIterator. The autograd engine performs the reduction assuming
standard broadcasting if the gradient shape does not match the
expected shape. Functions that do not use standard broadcasting rules
should either continue to trace the expand calls or handle the
reduction in their derivative formula.
- Use ONNX v7, which supports broadcasting ops.
Performance impact:
- Small increased fixed overhead (~0.5 us)
- Larger overhead for wrapped numbers (~2.5 us)
- No significant change for ops on contiguous tensors
- Much faster worst-case performance for non-contiguous GPU tensors
- Faster CPU bias addition (~2x)
- Faster GPU bias addition (~30% faster)
Future work:
- Decrease overhead, especially for wrapping numbers in Tensors
- Handle general inter-type operations
- Extend to unary ops and reductions
- Use buffering for compute-bound operations on non-contiguous tensors

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/9497Fixes#7883 by using `rfft`.
It's worth noting that this is BC breaking. And it's impossible to detect the change because the two signatures before and after this change supports a common subset of calling patterns, e.g., `stft(Tensor, int, int)`. (some other calling patterns will raise error).
soumith and I plan to change the current `stft` interface because it is a bit messy and non-standard. rafaelvalle suggested us that `librosa` is a good reference API to align with. After discussing with soumith and ezyang , and given that `stft` is only out for 1 release, I decide to go with directly changing the signature. Also, my understanding is that most researchers in this field will welcome this change as `librosa` seems to be the golden-standard here. (it doesn't yet support all `pad_mode` but those will become available if added to `F.pad`.)

Summary:
test_cuda.py uses routine 'number' to prepare many testscases.
number should return a floating point value for float-type tensor
types, or integer otherwise. But number's test to classify the type
is incorrect, so it always returns the integer value.
(type(t).__name__ is always 'torch.tensortype' so never matches
'Double', 'Float', or 'Half'.)
Update number to use the existing is_floating() helper to make the
check.
The change to number causes a few tests to fail for HalfTensor. Relax
the tolerance for those in line with other HalfTensor testcases. The
failing tests--for addcdiv and fill--were not previously relaxed for
HalfTensor so are held to the over-strict 1e-5 default tolerance.
Finally, update a couple other tests for HalfTensor type to use the
existing is_half() helper.

2. Fix BN (both THNN and cuDNN) not working on non-contiguous inputs.
3. Fix CUDA EmbeddingBag not working on non-contiguous inputs. To prevent calling `.contiguous()` on in both `forward` and `backward`,
a. prefix all current `embedding_bag*` functions with `_`, indicating that they require input to be contiguous (there is a check in each function).
b. create `embedding_bag`, which makes input arguments `.contiguous()`, and calls `_embedding_bag`
3. Make many ATen `embedding*` functions to work on non-contiguous inputs so we don't need to call `input = input.contiguous()` in Python `nn.functional.embedding`.
4. Fix dense-sparse addition when the sparse input is not coalesced and indices or values tensor is not contiguous. This came up in the test cases of Embedding modules with `sparse=True`. Added tests.
5. Update `TensorUtils.cpp` to use `AT_*` macros.
Request:

* Some 0-sized dimension support, port catArray away from resizeLegacy.
The goal of this PR is to port catArray away from resizeLegacy (so we can delete the legacy resize calls), but since catArray has some weird behavior because
we don't have arbitrary 0-sized dimension support, I made some effort to fix these both in one pass.
The major changes here are:
1) catArray uses the new resize API, no longer the old resizeLegacy API.
2) As 1) is the last usage of resizeLegacy, it is deleted.
3) If compiled with USE_TH_SIZE_ZERO_DIM, catArray will work and properly check shapes for n-dimensional empty tensors.
4) However, we retain the old behavior of "ignoring" size [0] tensors in catArray. We previously allowed this because we didn't have n-dimensional empty tensors.
5) To get the above to work, we also add support for n-dimensional empty tensors for narrow and slice (ifdef USE_TH_SIZE_ZERO_DIM).
6) We change the stride formula for empty tensors to match NumPy; basically, we never multiply by 0 as the size, always at least 1, so the
strides are monotonically increasing in the empty tensor case.
7) We print the size of empty tensors if size != [0]; this matches NumPy behavior (even in cases where the size could be inferred from the brackets.
8) For test purposes, we add torch._C._use_zero_size_dim() to add tests for the above.

* Raise error when torch.load a storage on a non-existing device
Before, doing torch.load(...) on a CUDA tensor on a CPU-only machine
would raise an unreadable error:
```
~/pytorch/pytorch/torch/cuda/__init__.py in __enter__(self)
223 if self.idx is -1:
224 return
--> 225 self.prev_idx = torch._C._cuda_getDevice()
226 if self.prev_idx != self.idx:
227 torch._C._cuda_setDevice(self.idx)
AttributeError: module 'torch._C' has no attribute '_cuda_getDevice'
```
This PR makes it so that torch.load raises a hard error if one tries to
load a storage onto a non-existing device and suggests the user to use
torch.load's map_location feature.

* Make THStorage / THCStorage have void* data ptr. (#7964)
* Make THStorage / THCStorage have void* data ptr.
This is the initial step in unifying the ATen and TH tensor representations, next is to only generate a single THStorage / THCStorage type.
The major changes here are:
1) data has been renamed to data_ptr and made void* in THStorage/THCStorage.
2) THStorage / THCStorage stores a at::ScalarType representing its data type (This will be useful when we generate a single THStorage/THCStorage).
3) APIs for Accessing the data as a real*:
a) storage->data<real>() -- this does runtime-type checking (checks that the at::ScalarType is correct).
b) storage->unsafeData<real>() -- as above, but no runtime-type checking (used in inner loops / fast code paths).
c) THStorage_(data)(storage) -- this already existed, just calls storage->data<real>().

If there is no python bindings, then a default Engine is constructed

one gets created before the python bindings are loaded. This case
is rare, and just results in additional threads being spawned.

* [CUDA9] Upgrade - fbcode
CUDA9 upgrade diff D5654023 has been out for a while thanks to Pieter. But with time growing it's becoming quite hard to rebase, because of the symlinks and auto-generated build/config files in tp2. Break D5654023 into two diffs, one touching tp2 config files, and another one touching fbcode TARGETS file (adding nvcc flag). These two should be a bit easier to rebase (for detailed procedure see "Test Plan").
This diff can only be committed if:
1. CUDA 9 rpm is rolled out fleet-wide (TBD)
2. NVidia driver 390.40 is rolled out fleet-wide (done)
3. Upgrade CUDA 9.1, cudnn 7.1, nccl 2.1 (done)

* Reduce usages of TensorUtils<T>::DataType in THC. (#8056)
TensorUtils<T> is basically ATen-dispatch-lite in that it allows one to do multi-type THC function dispatch with a single call.
However, it is templatized on the Tensor type, and since we are moving to a single Tensor type, this doesn't work.
Most of the functions in TensorUtils (e.g. getDims) can be pulled up a level, to just call THCTensor_nDimension (or directly accessing the member),
but the DataType specific functions are more problematic.
So, this PR does two things:
1) Replaces calls of 'TensorUtils<THCTensor>::DataType' with 'real' since these are identical
2) Templatizes the THC_pointwiseApplyX functions to take scalar types. To ensure this is done correctly, we static_assert that the scalar type template parameter matches the scalar type of
the corresponding template parameter. We will need to get rid of these static_asserts in the future, but this is useful for now.

* Fix cuda.framework error on OSX. (#8136)
When compiling OSX with CUDA, Caffe2's build system uses
find_package(cuda) to get its grubby hands on the CUDA driver
library (for some strange reason, FindCUDA doesn't save this
information as a variable). Unfortunately, on OSX, sometimes
this picks up the cuda.framework folder, and then our build
system chokes to death because it doesn't try to link against
this as a framework. (Is the folder even a framework? I have
no idea).
This commit attempts to fix this in a two pronged fashion:
1. For some users, reducing the precedence of frameworks
using CMAKE_FIND_FRAMEWORK seems to help. So we set these
variables. However, this fix is not perfect; on my laptop
it doesn't actually solve the problem.
2. PyTorch doesn't actually need the CUDA driver API. So we
only add the dep when building Caffe2.

For non-generic function call implementations in Storage used by TensorUtils, we do the following:

2) Move the implementation from generic/C++ to non-generic/C++.
3) Change the generic implementation to call the non-generic implementation.
This will allow us to get rid of the corresponding TensorUtils calls (once we move over the Tensor functions in the same manner).

We don't want SOVERSION because pip will lose the symlink and
double your distribution size, and also because our setup.py
accidentally links against both libcaffe2.dylib and libcaffe2.1.dylib
on OS X. This leads to a very puzzling error where you get
the error "cannot initialize CUDA without ATen_cuda", because
there are actually two copies of your registry in memory (because
there are two copies of the dynamic library). Dropping SOVERSION
makes it impossible to make this mistake.
In principle, if the shared library load is done with DYLD_GLOBAL,

If `t` is a scalar sparse tensor, `t._indices` used to return a sparse

the scalar check to return a dense tensor instead of a sparse tensor.

tensor = torch.sparse_coo_tensor([], [], torch.Size([]), device=device)

* Replace (non-data) TensorUtils calls with non-generic THCTensor calls. (#8176)
* Replace (non-data) TensorUtils calls with non-generic THCTensor calls.
TensorUtils is templatized on the THTensor type, so to support a single tensor type (like ATen), we need to remove these.
This PR does the following:
1) Allows THCTensorTypeUtils.cuh to include THCTensor.hpp.
This involves moving includes of it outside of generic/, so we can use the new implementations.
2) Defines a single _THTensor struct and changes THCRealTensor to be a derived type of _THCTensor.
This allows us to implement a single non-generic function and avoid static_cast or void * tricks to call it from the generic functions.
3) For functions inside of TensorUtils that don't use data pointers:
a) Implement the functions in (non-generic) THTensor.cpp and declare them in (non-generic) THTensor.hpp.
b) Have the generic versions call the non-generic versions.
c) Replace the corresponding TensorUtils<THCTensor>::fn call with (non-generic) THTensor_fn.

* move THCP-related utils to cuda/utils.cpp. (#8221)
These files don't follow the usual pattern: In general the files torch/csrc/X torch/csrc/cuda/X
both include the generic file torch/csrc/generic/X, where torch/csrc/X includes the cpu implementations and torch/csrc/cuda/X includes the cuda implementations.
(Aside: this is probably not the best structure, the torch/csrc/X fiels should probably be moved to torch/csrc/cpu/X).
utils.cpp combines these so that torch/csrc/utils.cpp has cuda specific code. This makes it impossible to declare a single THTensor and THCTensor template type (i.e. THPPointer<_THTensor>, THPointer<_THCTensor>).

* Don't override Tensor, Storage macros defined outside torch/csrc in torch/csrc.
This PR does the following:
1) Removes THSTensor macros in torch/csrc, which aren't used.
2) For macros defined outside of torch/csrc (THTensor, THTensor_, THStorage, THStorage_):
a) No longer override them, i.e. previously THTensor could actually be THCTensor if a generic file was included from a file including THCP.h.
b) Instead, introduce new macros THW* (e.g. THWTensor) to represent a (potentially empty) wildcard character.
In addition to making this code easier to read and codemod, this allows us to more freely change TH/THC; for example:
currently in the THC random code, the state is casted to THByteTensor*; this happens to work because the macros don't happen to override THByteTensor.
But if THByteTensor just becomes an alias of THTensor (which is the plan for a single tensor type), then this no longer works.
The whole thing is a bit of a mess previously because you really have to understand which macros and redefined and which aren't.
We could also rename the macros that live in torch/csrc (e.g. the THPTensor macros), but since that is more self contained, I punted for now.

* Raise error when torch.load a storage on a non-existing device
Before, doing torch.load(...) on a CUDA tensor on a CPU-only machine
would raise an unreadable error:
```
~/pytorch/pytorch/torch/cuda/__init__.py in __enter__(self)
223 if self.idx is -1:
224 return
--> 225 self.prev_idx = torch._C._cuda_getDevice()
226 if self.prev_idx != self.idx:
227 torch._C._cuda_setDevice(self.idx)
AttributeError: module 'torch._C' has no attribute '_cuda_getDevice'
```
This PR makes it so that torch.load raises a hard error if one tries to
load a storage onto a non-existing device and suggests the user to use
torch.load's map_location feature.
* Address comments
* missing dep
This PR makes two improvements:
It fixes reduce kernels where accum type != type. Currently, for example, half tensors with small values may have norms that are (approximately) representable in fp16, but calling .norm() on them will result in underflow and a reported norm of zero. This PR fixes that behavior and adds a test in test_cuda.py to ensure underflow does not occur (test_tiny_half_norm).
It simplifies all reductions by removing excessive templating and the -2 contiguous special case from THC_reduceDim and THC_reduceAll. The latter was previously removed from pointwise apply. This has no performance impact as the -2 special case was already mapping to the 1D code path.
PyTorch currently attempts to handle accum type != type by either (1) writing kernels that immediately convert values to accum type after reading or (2) writing operations that take in type values and accumulate to the accum type. The latter path was not working properly (hence the current excessive half tensor underflow) and resulted in a lot of redundant code, with two reduce ops being passed to a kernel instead of one, and reduce ops frequently receiving the same template argument twice.
This PR makes the former approach THE approach. Kernels that accumulate to (potentially) different types should follow the pattern of converting their input to the accum type, performing all operations on that type, and then converting back to the appropriate type if writing their value back to the tensor. This pattern makes the second reduce op redundant and allows for simpler templating, which should improve readability, reduce build time, and reduce binary size. Also, this prevents ops from having to perform their own conversions, which could result in poor performance if the same value was operated on multiple times.
One exception to this simplification was that a new ThrustTensorDistOp was created to handle a call to thrust::inner_product(). This Op fuses the conversion and the TensorDistOp.
In addition to the expected simplification, there is also some cleanup of excessive template parameters. For example, kernelReduceAllPass2() had three template parameters: T, IndexType, and ReduceOp, but IndexType was never used.

I moved `gesv` to ATen.
Adds bindings for MAGMA's `gesv_batched` function for CUDA.
For CPU, runs `THLapack(gesv)` in a for loop.
The new function supports arbitrary batch dimensions (and broadcasting
of those dimensions). For example, the 4-d tensor `A x B x M x M` should
be treated as having batch-size `(A x B)`.
The overhead of creating the magma_queue_t is: ~350000 microseconds
the first time it's called and ~6 microseconds every time after that.

* Changes incorrect "overlappingIndices" call to correct "maybeOverlappingIndices"
THE PROBLEM
The current overlappingIndices() is meant to detect if a tensor defines multiple valid indices for the same data element. There are two significant issues with this function:
(1) The algorithm it attempts to implement cannot do this.
(2) That algorithm is not implemented correctly.
This call is used by pointwiseApply() and scatter(). If a tensor is readable/writable and detected as overlapped these algorithms will create a non-overlapped copy of it to work on. When tensors are improperly identified as overlapped this causese extra work. If tensors are improperly identified as non-overlapped then this would cause the operations to exhibit unexpected behavior.
For example,
ref = torch.arange(0, 32 * 5).view(4, 8, 5).cuda().double()
p = ref[:,:,::2]
p += 1
Results in a call to pointwiseApply1, which detects p as an overlapped tensor (it is not), causing a call to pointwiseApply2 that copies it into a non-overlapped temporary, and then another call to pointwiseApply2 later that copies it back to the original tensor. If, however, the original tensor is given dimensions of (4, 8, 4), instead, it is correctly detected as non-overlapped and only a single pointwiseApply1 call is made.
DISCUSSION + FIX
The algorithm that overlappingIndices() attempts to implement tests for a sufficient but not necessary condition of a tensor to be non-overlapping. That is, if its algorithm were implemented properly then it would be a conservative check that would ensure all overlapped tensors were copied (as desired), but also that some non-overlapped tensors were copied too.
The algorithm can be thought of as trying to test whether the dimensions can be ordered like "nesting dolls," with each dimension fitting within the next one larger than it. If this is true then the tensor is non-overlapping, but if it's false the tensor may or may not be overlapped. For example, a tensor with dims (2, 3) and strides (4, 3) cannot be "nested," but is non-overlapping. (The tensor looks like [[0, 3, 6], [4, 7, 10]].)
The algorithm is currently implemented improperly, as can be seen in the example above. The tensor p has dimensions [4, 8, 3] and strides [40, 5, 2]. This confuses the current implementation, which thinks the innermost dimension needs a stride of 6, which is incorrect. The first row is [0, 2, 4] and the next row begins with 5. The current implementation also improperly implemented its sorting behavior. (qsort comparators require -1, 0, and 1, not true/false return values.)
Fixing the existing algorithm is straightforward (and what this PR does, see below), but it is important to note that the algorithm never performed as intended, so its name and the documentation around it has been updated, too. A natural question is if it's possible to write an efficient overlappingIndices(), and I believe the answer is "no." Disambiguating overlapping from non-overlapping tensors is equivalent to finding a nonzero solution to a linear diophantine equation with restricted coefficients, that is, an equation of the form x_0s_0 + x_1s_1 ... = 0 where s_X is the stride in dimension X and x_X is an integer from [-size_X + 1, size_X - 1].
Another note is that the CPU does not perform this check. For example, if we run:
a = torch.FloatTensor([[0,1], [10, 11]])
b = torch.FloatTensor([[0,0],[0,0]])
b = b.set_(a.storage(), storage_offset=0, size=a.size(), stride=(1,1))
b += 1
Then b is [[1, 3], [3, 11]] because the operation is applied twice to the second element of the original tensor. This causes no warning.
Since the CPU does not perform a similar check, another question is whether the GPU code should remove its check. While it may seem that writing to overlapping tensors is an error state, running test_cuda.py reveals 171 instances of possibly overlapped tensors being copied by pointwiseApply(). (The prior incorrect version has 176 copies.) Allowing writing to overlapped tensors on the GPU may violate assumptions about memory accesses, too. In fairness, these assumptions may be violated on the CPU already.
Leaving the CPU vs GPU behavior question for the future, this fix corrects the current intended GPU behavior. This means that there will be fewer unnecessary copies and no chance of an overlapped tensor sneaking through on the GPU. The CPU behavior remains unchanged. The fix also adds a test to test_cuda.py to ensure that overlapped tensors on the GPU are written to as expected.
* cleanup
* Fixes Python formatting
* Fix performance regression on simple cases of indexing
Dispatches to the old kernels
* Adapt JIT test
The test was expected to fail, but due to the change in the previous diff, it would now dispatch to index_select, which succeeds. I modified the function to go through the advanced indexing codepath
* Only do checks once, properly AutoNoGil, AutoGPU.
* Fix cross device indexing for more than 1 cuda device.
Cross device indexing is attempted from ATen, which doesn't work well because ATen doesn't have AutoGPU, etc.
Instead, before dispatching to ATen we do type conversion on the indices; it would probably be better if we
pushed all this down to ATen, but that will take some work.
* Small cleanup.
* Codemod to update our codebase to 0.4 standard
* Update some of the test scri[ts
* remove Variable in test_clip_grad_value
* fix _symbolic_override_wrapper_maker
* More precise digamma
Fixes#6190.
This is a rebase of #3955 with some tweaks for better performance around
poles. The code is ported over from cephes with permission.
By itself, the cephes code returns inf for the poles.
For better performance around the poles with float32, one intermediate
step is always computed with double precision, regardless of dtype.
This step does `PI / tan(PI * input)`. This is necessary because small (1e-6)
rounding errors for the inputs to tan have strong effects on the output
(ie, the derivative of tan is very large at some points).
* Replace usages of finite-differences digamma with newly implemented digamma
* Better behavior near and at poles
* ScalarConvert -> scalar_cast for readability
* Separate cuda-ness from dtype.
There are no longer torch.cuda.int64, etc; only torch.int64 that correspond to at::ScalarType.
At the python arg parser level, the corresponding ATen type is selected from the combination of (ScalarType, Layout, Device).
There is also currently unused code in here for support ScalarType in native_functions; this will be used for specifying aggregate types
on reduction functions.
* Fix test_autograd.
* Add defaults to randint_like.
* Track is_cuda in py tensor types.
* Fix test_sparse.
* Fix multiprocessing.
* Fix rnn.
* Fix test_nn.
* Fix flake8.
* Implemented log2 and log10
* Re-add incorrectly removed files
* Fix minor bugs
* Fix log1p docs
* Add a try-except for python2 math module in log2 test
* Revert changes made to aten/doc/*
* Fix docstring errors
* Fix windows build
This is in preparation for splitting out sparsity (layout) from dtypes; it's complex to maintain these
and tensor.new(...) is a legacy API in any case.
* Fix integer overflow in remainder
* Fix remainder operator in CUDA
* Add tests for remainder integer overflow
* Add has_different_sign static function
* 1. Add logdet and slogdet in ATen side
2. Previously, det can return result with incorrect sign upon seeing symmetric
matrices. This is caused by the wrong assumption I had on SVD (when input is
symmetric U=V^T). This fixes it.
3. Moreover, after fixing 2 now QR is always needed for det forward. So I moved
SVD to backward call. Since this is a specific variant of SVD, it is named as
_svd_with_positive_UV_det, with derivative.yaml entry being svd_backward.
4. Updated/added backward functions for det, logdet and slogdet, which uses
_svd_with_positive_UV_det and svd_backward inside.
5. Optimized svd_backward:
a. Avoid unnecessary kernels when only sigma has gradient (this is the usual
case, and also true with *det backward functions).
b. Fix SVD double backward by avoiding a nan.
* 1. Add/update grad checks for det, logdet, and slogdet.
2. Fix an incorrect check for dim_args_idx in test_autograd.py
3. Add option to only test a subset of output values, specified by
test_output_indices, for cases like slogdet where only the
second output is differentiable.
4. Add better doc for the test generating list.
* Add/improve output tests for det, logdet and slogdet
Add a scaling to random matrices so closeness checks are more robust
* Remove unnecessaery Variable wrappers in some test files
* Add logdet slogdet docs
* Improve an err msg in THTensorLapack.c
* add inverse-based backward for invertible matrices
use svd only for non-invertible case, so don't need the special variant anymore
* use LU rather than QR
* CPU int-types pow()
* CUDA int-type pow()
* Cleanup + fix deleted line
* Tests for integer-types pow
* Fix build
* Fix windows tests
* Make _test_int_pow static
This PR enables the following tests on Windows again:
CUDA HalfTensor tests in test_torch.py and test_nn.py
test_Conv2d_deterministic_cudnn in test_nn.py
test_*Tensor_qr_big in test_cuda.py
The issues are no longer reproducible, possibly because of an upgrade to the display driver.
* Reenable CUDA HalfTensor tests on Windows
* Reenable test_Conv2d_deterministic_cudnn on Windows
* Reenable test_*Tensor_qr_big on Windows
* Support dtypes in legacy new constructors.
* Add comment about why we don't have dtype for sparse (indices, values).
* separate legacy tensor ctor vs new (new includes dtypes).
* Use TypeError.
This replaces the torch.Tensor constructors with factories that produce
Variables. Similarly, functions on the torch module (e.g. torch.randn)
now return Variables.
To keep the PR to a reasonable size, I've left most of the unused tensor
code. Subsequent PRs will remove the dead code, clean-up calls to
torch.autograd.Variable, and rename Variable to Tensor everywhere.
There are some breaking changes because Variable and Tensors had
slightly different semantics. There's a list of those changes here:
https://github.com/pytorch/pytorch/wiki/Breaking-Changes-from-Variable-and-Tensor-merge
Their cuda kernels should be initialized with (min_value, 0) and
(max_value, 0), respectively, where the second number is a default index
value. However, they were being initialized with (max, 1) and (min, 1)
instead, probably a remnant from the lua torch days.
This caused bugs in torch.max() and torch.min() when the input is at the
extreme values, and the max value (or min value) occurs at index 0. For example,
import torch
x = torch.ByteTensor([[0]])
x.cuda().max(dim=0) # returns (0, 1) but the expected result is (0, 0)
The test_cuda.py setup purports to test half tensors, but actually just
re-tests FloatTensors because the keys in type_map were str instead of
type. Testing HalfTensors is more complicated, requiring changes to
precision and requires excluding some unimplemented methods.
We should fully test half CUDA tensors. This change just deletes the
duplicate tests of FloatTensor.
* Replace async with non_blocking for Python 3.7 upgrade
* Remove trailing whitespace
* Give _cuda and _type kwargs and accept async for compatibility
* Rename async to non_blocking in all C++ code
* Add entries for async in python_variable_methods
* Friendlier backward compatibility for cuda and type
Variable.new() should default to the device of "self" if no device is
specified. Previously, we were using the current device. This now
matches Tensor.new().
* Fix catArray in THTensor
Asserts that the inputs have the same size except in the
cat dimension or are empty (or a mix of both).
* Fix catArray for THCTensor
* Document torch.cat shape checks
* Fix types
* Implement Variable.cuda using ATen
This adds an optional async flag to Tensor::copy_, which attempts to do
a non-blocking copy if the one of the tensors is in pinned memory and
the other is a CUDA tensor.
* Perform cross-device copy in CopyBackwards
Also call torch.cuda._lazy_init() from Variable.cuda()
* Implement Variable.type via ATen
* Changes from review:
- remove copy_out
- remove unnecessary include
- fix default device for .cuda()
* Combine if statements in dispatch_type
* Better error messages for blas ops with cuda.LongTensor
Fixes#4157
Test plan
Try matrix multiplying with cuda.LongTensors
>>> import torch
>>> x = torch.randn(4, 4).long().cuda()
>>> y = torch.randn(4, 4).long().cuda()
>>> x.mm(y)
Traceback (most recent call last):

at() at /private/home/rzou/pytorch/pytorch/aten/src/THC/generic/THCTensorMathBlas.cu:381
* Use Welford's algorithm when reducing along inner dimension for THCTensor's variance fn
* Use accreals in THCTensor's varInnermostDim
* Skip cuda tests if no cuda
* Variance testing
* Add torch.take and Tensor.put_
These are similar to numpy.take and numpy.put. The take function allows
you to linearly index into a tensor without viewing it as a 1D tensor
first. The output has the same shape as the indices. The put function
copies value into a tensor also using linear indices.
* tensor: Ensure that the tensor is contiguous before pinning (#3266)
pin_memory() was producing out-of-order tensor when the given
tensor was transposed, i.e. in column-major order.
This commit fixes this by calling contiguous() before pinning.
* test: add contiguous test for pin_memory (#3266)
* with the size=1 case, impossible to do single point check, replace with isContiguousRange
* fix stride in desc; fix undef scope
* add test for this case for cudnn
* assertTrue
test_FloatTensor_qr_big test is still a bit flaky on K80. Increasing tolerance to improve reliability as tests are moved around and results change for this test.
Here's the command I used to invoke autopep8 (in parallel!):
git ls-files | grep '\.py$' | xargs -n1 -P`nproc` autopep8 -i
Several rules are ignored in setup.cfg. The goal is to let autopep8
handle everything which it can handle safely, and to disable any rules
which are tricky or controversial to address. We may want to come back
and re-enable some of these rules later, but I'm trying to make this
patch as safe as possible.
Also configures flake8 to match pep8's behavior.
Also configures TravisCI to check the whole project for lint.
* Fix error in ELU backward
* Add --seed flag for testst st
* Add test for BatchNorm eval
* Fix autograd.backward docs
* Support cc flags in cuDNN search
* Fix IndexSelect backward formula
See issue #20
The torch.Size class is a tuple subclass which distinguishes sizes from
other tuples so that torch.Tensor(size) is interpreted as size instead
of data.
