Make it so that it is valid to set metadata after detach calls, like `x.detach().resize_(...)`.
This technically lifts some restrictions around `.data`. This PR means that you can now technically call `x.data.resize_(...)`, which can now directly resize `x` instead of erroring.
My understanding: Before the tensor-variable merge, when `x` and `x.data` were really different tensors, you could resize `x.data` independently of `x`, and during the merge, this error was added to avoid silent confusing behavior changes.
It was agreed that this error has been around long enough (several years) that it's acceptable to drop. cc @albanD @ezyang.

Add support for sparse fake tensors.
- The testing strategy is to run a fake tensor cross ref test on `test_sparse.py`. This is necessary because OpInfo sparse coverage is completely nonexistent. We could have tried to turn on cross ref testing globally for all files, but that would be very time consuming and the tests I'm interested in are mostly in this file. There are some exclusions in testing for things that don't work.
- I make fake tensor converter raise a UnsupportedFakeTensorException if the meta converter fails to do a conversion (which can happen in a relatively large number of situations).
- I relax fake tensor invariants so that you can make a fake tensor from a meta tensor. This is useful because in the cross ref test sometimes we operate on meta tensors.
- Fake tensor wrapping is improved to handle the case when a function doesn't return any tensors
- Meta converter is taught how to convert sparse tensors to meta
There's still a little more cleanup that needs to be done, but this is good for review.

Part of #70926
In other functions (ie (torch.diagonal)[https://pytorch.org/docs/stable/generated/torch.diagonal.html#torch.diagonal]) diagonals of a tensor are referenced using the offset and the two dimensions that the diagonal is taken with respect to.
Here the reference implementation from scipy is only considering matrix output, so even if we only support 2-d output at first. It may be useful to consider how the dimensions corresponding to each diagonal would be specified for higher dimensional output.
The proposed torch signature implies that all offsets refer to the diagonals with respect to the only two dimensions of the output:
```
torch.sparse.spdiags(Tensor diagonals, IntTensor offsets, int[] shape, Layout? layout=None) -> SparseTensor
```
Above it is required that: `diagonals.ndimension() == 2`, `offsets.ndimensions() == 1`, `offsets.shape[0] == diagonals.shape[0]` and `len(shape) == 2`.
This would need to be altered for the case where `len(shape)` > 2. One options is:
```
torch.sparse.spdiags(Tensor[] diagonals, IntTensor[] offsets, IntTensor dims, int[] shape, Layout? layout=None) -> SparseTensor
```
Here `offsets` and `diagonals` becomes lists of tensors, and the `IntTensor dims` argument is introduced. This would require that `len(diagonals) == len(offsets) == dims.shape[0]`, `dims.ndimension() == 2` and `dims.shape[1] == 2` also the same restrictions as the 2d case above apply to the elements of `diagonals` and `offsets` pairwise (that is `diagonals[i].ndimension() == 2`, `offsets[i].ndimension() == 1` and `offsets[i].shape[0] == diagonals[i].shape[0]` for all i). This form of the signature would construct the sparse result by placing the values from `diagonals[i][j]` into the diagonal with offset `offset[i][j]` taken with respect to dimensions `dims[i]`. The specialization back to the original signature for the 2d case could be seen as allowing the single row of dims to default to `[0, 1]` when there is only one `diagonals`, `offsets` provided, and shape is `2-d`. This option allows the rows of an input element `diagonals[i]` to have a different length which may be appropriate as the max length of a diagonal along different dimension pairs will be different.
Another option is to specify the dimensions the diagonal is taken with respect to for each offset. This signature would look like:
```
torch.sparse.spdiags(Tensor diagonals, IntTensor offsets, IntTensor dims, int[] shape, Layout? layout=None) -> SparseTensor
```
Here, `diagonals` is still 2-D with dimension 0 matching the length of 1-D `offsets` and the tensor input `dims` is also 2-D with dimension 0 matching the length of 1-D `offsets` and the second dimension being fixed at `2` in this case the sparse result is constructed by placing the elements from `diagonals[i]` into the output diagonal `output.diagonal(offset[i], dim0=dims[i][0], dim1=dims[i][1])` (with some additional consideration that makes it more complicated than simply asigning to that view). The specialization from this back to the 2-D form could be seen as assuming `dims = [[0, 1], [0, 1]... len(offsets) times ]` when `len shape==2`.
In both proposed signatures for the N-D case the specialization back to the 2-D signature is a bit of a stretch for your typical default arguments logic, however I think the first is better choice as it offers more flexibility.
I think some discussion is required about:
- [x] Should the N-D output case be implemented from the outset
- [x] If not, should the future addition of the N-D output case be considered when designing the interface.
- [x] Other thoughts on the signature which includes the `dims` information for the N-D output case.
**Resolution**: Since no one has offered a request for N-D output support, I think is fine to restrict this to sparse matrix generation. Should a request for N-D support come later, an overload accepting the additional `dims` could be added.

This is a re-land of D35192346 (9872a06d77) and D35192317 (a9216cde6c), which together are a diff that changes the internal representation of `DispatchKeySet` in pytorch core to free up the number of dispatch keys that we have available. See a more detailed description of the design in the original PR: https://github.com/pytorch/pytorch/pull/69633.
The original PR broke Milan workflows, which use a pytorch mobile build, and manifested as a memory corruption bug inside of `liboacrmerged.so`.
**Background: Existing Mobile Optimization**
Pytorch mobile builds have an existing optimization (here cc23725e89/c10/core/DispatchKey.h (L382) and here cc23725e89/aten/src/ATen/core/dispatch/OperatorEntry.h (L214)), which works as follows:
Every operator in pytorch has a "dispatch table" of function pointers, corresponding to all of the (up to 64) different kernels that we might dispatch to when we run an operator in pytorch (autograd, cpu, cuda, complex number support, etc).
In mobile builds, the size of that table is shrunk from 64 to 8 to save a bunch of space, because mobile doesn't end up using the functionality associated with most dispatch keys.
The dispatcher also has a notion of "fallback kernels", which are kernels that you can register to a particular dispatch key, but should be able to work for "any operator". The array of fallback kernels is defined here: cc23725e89/aten/src/ATen/core/dispatch/Dispatcher.h (L294).
The mobile-optimization currently does **not** extend to this array (it wouldn't be that useful anyway because there is only one array of fallback kernels globally - vs. there is a separate dispatch table of function pointers per operator). So the per-operator tables on mobile are size 8, while the fallback table is size 64.
**The Bug**
This PR actually makes it difficult to enable that optimization separately for the per-operator arrays vs. the fallback array, and incidentally shrunk the size of the fallback array from 64 to 8 for mobile (that happened on this line: https://github.com/pytorch/pytorch/pull/69633/files#diff-f735cd7aa68f15b624100cbc4bb3b5ea76ffc7c9d3bec3b0ccabaa09609e5319R294).
That isn't a problem by itself (since mobile doesn't actually use any of the fallbacks that can no longer be stored). However, pytorch core will still register all of those fallback kernels on startup in mobile builds, even if they aren't used. When we tried to register one of those fallbacks on startup, it would try to dump the kernel somewhere in memory past the bounds of the (now smaller) array inside of the `Dispatcher` object, `backendFallbackKernels_`.
**Why didn't this problem show up in OSS CI? Why didn't it break other internal mobile workflows aside from Milan?**
Ideally, this failure would show up as part of the OSS signal on GitHub, since we already have mobile OSS builds. Given that it was another memory corruption issue that only affected Milan (subset of mobile), I'm not sure what's specific about Milan's builds that caused it only to manifest there. dreiss I wonder if there's another flavor of mobile builds we could run in OSS CI that could potentially help catch this?
**The debugging experience was pretty difficult**
Debugging the Milan-specific failure was made difficult by the following:
(1) lack of CI
- the original Milan failure didn't surface on my original diff, because the Milan job(s) that failed weren't triggered to run on pytorch changes. There's probably a balance to strike here, since those jobs will only be useful if they aren't flaky, and if they can produce reliable failure logs for debugging.
(2) It's difficult to get a repro.
- my work laptop doesn't have the right specs to run the Milan development workflow (not enough disk space)
- There is an existing OnDemand workflow for Milan, but it appears to be relatively new, and after a bunch of help from MarcioPorto, we ran into issues forwarding the log output from Milan tests on the emulator back to the terminal (see the original discussion here: https://fb.workplace.com/groups/OnDemandFRL/permalink/1424937774645433/)
(3) Lack of stack-traces.
- Most Milan failures didn't include actionable stack traces. phding generously helped me debug by running my suggested patches locally, and reporting back if there were any failures. The failing test didn't include a stack trace though (just the line where the crash appeared), so I ended up making some educated guesses about what the issue was based on the area of the crash.

The masked sum on a full input tensor (of any layout) with an all-true mask is the same as the sum on the strided input tensor (after applying `to_dense` to sparse inputs).
Since masked sum uses `torch.sparse.sum` then, for the simplicity of masked reductions implementations, its reduction behavior ought to be defined by the behavior of the `torch.sum`. This PR implements the behavioral connection with respect to the directional summation of empty sparse tensors that correspond to all-zero strided tensors.

Following https://github.com/pytorch/pytorch/pull/61840#issuecomment-884087809, this deprecates all the dtype getters publicly exposed in the `torch.testing` namespace. The reason for this twofold:
1. If someone is not familiar with the C++ dispatch macros PyTorch uses, the names are misleading. For example `torch.testing.floating_types()` will only give you `float32` and `float64` skipping `float16` and `bfloat16`.
2. The dtype getters provide very minimal functionality that can be easily emulated by downstream libraries.
We thought about [providing an replacement](https://gist.github.com/pmeier/3dfd2e105842ad0de4505068a1a0270a), but ultimately decided against it. The major problem is BC: by keeping it, either the namespace is getting messy again after a new dtype is added or we need to somehow version the return values of the getters.

Before this change, a deprecation warning was triggered within the C++ implementation of floor_divide:
```
UserWarning: floor_divide is deprecated, and will be removed in a future version of pytorch. It currently rounds toward 0 (like the 'trunc' function NOT 'floor'). This results in incorrect rounding for negative values.

Summary:
The `ops` decorator provides a way to parameterize a test across a given list of ops. This would be useful for modules as well (e.g. a `modules` decorator), but the mechanism by which this is accomplished is specific to ops. In the details, the `ops` decorator tags a test function with the metadata needed (list of ops, `dtypes`) and the actual tests are generated according to this metadata during the call to `instantiate_device_type_tests()`.
This PR makes this mechanism more generic, allowing for test parameterization across arbitrary dimensions. This makes a `modules` decorator (or any similar type of decorator) straightforward to implement without changes to the device-specific test instantiation logic.
One caveat is that, since this is implemented where the old `ops` decorator was (within `instantiate_device_type_tests()`), this only works for tests instantiated using the device-specific instantiation logic. Longer term, even device-specific test instantiation could be treated as an optional parameterization across device types, but this PR takes a low-risk approach for now. In practice, this just means that a `device` kwarg is required for all test signatures used with the mechanism.
The `ops` decorator has been refactored to use the generic mechanism and works the same as before, with one difference: when `OpDTypes.none` is specified, the test signature no longer needs an unused `dtype` kwarg. This is a nice bonus that demonstrates the added flexibility of a generic parameterization mechanism. The refactored form also has the bonus that all op-specific test generation logic is contained within the `ops` decorator class, improving readability.
Behind the scenes, the generic mechanism is a base decorator class (`_TestParameterizer`) from which `ops` derives. The core functionality is in the `_parameterize_test()` method, which takes in a test function and returns a generator that produces parameterized tests, including names and parameter kwargs to pass to them. Using the `ops` decorator results in a set of op-specific tests from a given generic test.

Resubmit of https://github.com/pytorch/pytorch/issues/58811, Closes gh-24745
The existing PR (gh-50655) has been stalled because `TensorIterator` doesn't guarantee iteration order in the same way that `TH_TENSOR_APPLY` does. For contiguous test cases this isn't an issue; but it breaks down for example with channels last format. I resolve this by adding a new `TensorIteratorConfig` parameter, `enforce_linear_iteration`, which disables dimension reordering. I've also added a test case for non-contiguous tensors to verify this works.
This PR also significantly improves performance by adding multithreading support to the algorithm. As part of this, I wrote a custom `count_nonzero` that gives per-thread counts which is necessary to write the outputs in the right location.

- [x] add complex support to coalesce function
- [x] add complex support to to_dense function
- [x] add complex support to to_sparse function
- [x] add complex support to sparse_add function
- [x] add unit tests
Note: This PR contains only complex support for torch.sparse_coo_tensor fordward function and the related ops used with this function (coalesce, to_dense, to_sparse, and sparse_add). The following PRs in ghstack should cover other sparse operations to have a more complex sparse support, specifically related with the use of specific APIs for accelerated linear algebra.

Summary:
Fixes https://github.com/pytorch/pytorch/issues/52253
In the issue reproducer we can replace `torch.sparse.sum(S)` with `S.coalesce()` and get the same memory leak. The reason is that calling `coalesce()` on an already coalesced tensor returns `self`. With autograd, the result gets it's `grad_fn` set to a node that contains a reference to the input tensor, creating a reference cycle. Cloning the tensor fixes this, so `coalesce` always returns a new tensor.
As an aside, `torch.sparse.sum(S)` doesn't need to coalesce. The result should be the same either way.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/54034Fixes#53544
I had to touch a bunch of lines but the refactoring was fairly
mechanical. Here's how it works.
The basic concept behind this PR is that tensor_new.cpp was previously
abusing DispatchKey when it actually meant TensorOptions. The provided
DispatchKey argument to most of the constructor functions typically
comes from torch::tensors::get_default_dispatch_key(); it doesn't
really make sense for people to set the default dispatch key, but
this got grandfathered in due to the old API set_default_tensor_type
(where the "Type" concept got refactored into "DispatchKey" concept
over time). See also #53124. But the upshot is that, semantically,
what we refer to as the default dispatch key really is more like
torch.set_default_tensor_type(torch.Tensor) versus
torch.set_default_tensor_type(torch.cuda.Tensor): clearly the user
wants to do something about *construction* of the tensor, and
TensorOptions captures that exactly.
So, how exactly to translate from one to the other?
- Sources (things that used to PRODUCE DispatchKey)
- Most top level functions take a DispatchKey as their argument. I
use the new function dispatchKeyToTensorOptions to convert it into
a TensorOptions
- typeIdWithDefault now produces a TensorOptions (probably could do
with a rename, though I didn't)
- Sinks (things that used to CONSUME DispatchKey)
- Previously, the function options() was typically used to convert the
DispatchKey into a TensorOptions. Now its replacement build_options
just takes a TensorOptions and sets some extra fields on it.
Irritatingly, I can't just replace
`build_options(options, scalar_type, device)` with
`options.dtype(scalar_type).device(device)` because the semantics
are slightly different: if device is nullopt, we should preserve
the usage of the device specified in options (what options.device()
does is overwrite the device unconditionally; e.g., if device is
nullopt, unset device from options)
- The other major sink for DispatchKey was `internal_new_from_data`,
but it turns out it only really extracts the device type from
the dispatch key. Now it just pulls out the device from
TensorOptions.
- To actually do the translation of DispatchKey to TensorOptions, I
introduce new functions dispatchKeyToLayout (replicating
layout_from_backend--there are still a few uses of this function
so I couldn't delete it) and dispatchKeyToDeviceType (replacing
computeDeviceType)
- In all internal functions, whenever DispatchKey is taken as an argument,
I instead take TensorOptions as an argument, and pass it along.
- Anywhere `legacyExtractDispatchKey(other.key_set())` equality was
previously used, I now do `other.options().type_equal()`, which
is the intended BC for doing "backend to backend" comparisons
- There are a few places in the sparse constructors where we allocated
a tensor for values, and then read out the dispatch key from the
result to allocate the keys. As best as I can tell, this is totally
equivalent to just passing in the options to both values and indices
(the only difference is dtype, which is captured via a separate
argument)
This refactor doesn't really go far enough: for example, there are now
functions that take both TensorOptions and ScalarType, when really
the TensorOptions can capture this all. I kept it solely just
s/DispatchKey/TensorOptions/ to reduce the number of possible bugs;
also, a lot of this will be mooted by a proper fix to #53124.
Even with this limited refactor, the payoff is sweet. I can delete:
- backendToCPU
- backendToXPU
- backendToCUDA
- backendToHIP
- backendToBackendOfDeviceType
The reason I can do this is because I can simply overwrite layout in TensorOptions
to do the conversion, rather than having to type out each backend case
explicitly.

Summary:
**BC-Breaking Note:**
BC breaking changes in the case where keepdim=True. Before this change, when calling `torch.norm` with keepdim=True and p='fro' or p=number, leaving all other optional arguments as their default values, the keepdim argument would be ignored. Also, any time `torch.norm` was called with p='nuc', the result would have one fewer dimension than the input, and the dimensions could be out of order depending on which dimensions were being reduced. After the change, for each of these cases, the result has the same number and order of dimensions as the input.
**PR Summary:**
* Fix keepdim behavior
* Throw descriptive errors for unsupported sparse norm args
* Increase unit test coverage for these cases and for complex inputs
These changes were taken from part of PR https://github.com/pytorch/pytorch/issues/40924. That PR is not going to be merged because it overrides `torch.norm`'s interface, which we want to avoid. But these improvements are still useful.

Summary:
**BC-Breaking Note**
This PR changes the behavior of the torch.tensor, torch.as_tensor, and sparse constructors. When given a tensor as input and a device is not explicitly specified, these constructors now always infer their device from the tensor. Historically, if the optional dtype kwarg was provided then these constructors would not infer their device from tensor inputs. Additionally, for the sparse ctor a runtime error is now thrown if the indices and values tensors are on different devices and the device kwarg is not specified.
**PR Summary**
This PR's functional change is a single line:
```
auto device = device_opt.has_value() ? *device_opt : (type_inference ? var.device() : at::Device(computeDeviceType(dispatch_key)));
```
=>
```
auto device = device_opt.has_value() ? *device_opt : var.device();
```
in `internal_new_from_data`. This line entangled whether the function was performing type inference with whether it inferred its device from an input tensor, and in practice meant that
```
t = torch.tensor((1, 2, 3), device='cuda')
torch.tensor(t, dtype=torch.float64)
```
would return a tensor on the CPU, not the default CUDA device, while
```
t = torch.tensor((1, 2, 3), device='cuda')
torch.tensor(t)
```
would return a tensor on the device of `t`!
This behavior is niche and odd, but came up while aocsa was fixing https://github.com/pytorch/pytorch/issues/40648.
An additional side affect of this change is that the indices and values tensors given to a sparse constructor must be on the same device, or the sparse ctor must specify the dtype kwarg. The tests in test_sparse.py have been updated to reflect this behavior.

Summary:
This pull request disables the unit tests that were observed to be failing once `test2` was enabled. These tests will be one by one looked at and fixed at the earliest, but until then disabling them to unblock `test2`
The pull request also disables fftPlanDestroy for rocFFT to avoid double-freeing FFT handles

Pull Request resolved: https://github.com/pytorch/pytorch/pull/35615
Python 2 has reached end-of-life and is no longer supported by PyTorch.
Now we can clean up a lot of cruft that we put in place to support it.
These changes were all done manually, and I skipped anything that seemed
like it would take more than a few seconds, so I think it makes sense to
review it manually as well (though using side-by-side view and ignoring
whitespace change might be helpful).

Summary:
Per title. See related https://github.com/pytorch/pytorch/pull/34570.
In PyTorch 1.7 the plan is for torch.div and Python's division operator to perform "true" division, like Python 3, JAX, and NumPy. To facilitate this change, this PR expands true_divide to be a method so it can cover all of torch.div's use cases.
New true_divide tests are added to test_torch.py, test_type_promotion.py, and test_sparse.py.

Summary:
(Updated per review feedback)
`torch.floor_divide` is currently a function that can operate on two tensors or a tensor and a scalar (scalar x scalar floor division is handled natively by Python and the JIT has a builtin function for it). This PR updates it to:
- have an out variant: `floor_divide(x, y, out=z)`
- be a method on a tensor: `x.floor_divide(y)`
- have an in-place variant: `x.floor_divide_(y)`
- work with sparse tensors
Tests are added to test_sparse.py and test_torch.py for these new behaviors.
In addition, this PR:
- cleans up the existing sparse division and true_division code and improves their error message
- adds testing of sparse true_division to test_sparse.py
- extends existing floor_divide testing in test_torch to run on CUDA, too, not just the CPU
Unfortunately, making floor_divide a method requires breaking backwards compatibility, and floor_divide has been added to the BC whitelist since this is international. The BC issue is that the first parameter name to torch.floor_divide is changing from input to self. If you previously called torch.floor_divide with keyword arguments, e.g. torch.floor_divide(input=x, other=y), you will need to update to torch.floor_divide(self=x, other=y), or the more common torch.floor_divide(x, y).
The intent of this PR is to allow floor_divide to be substituted for division (torch.div, /) wherever division was previously used. In 1.6 we expect torch.div to perform true_division, and floor_divide is how users can continue to perform integer division with tensors.
There are two potential follow-up issues suggested by this PR:
- the test framework might benefit from additional tensor construction classes, like one to create dividends and divisors for multiple dtypes
- the test framework might benefit from a universal function test class. while methods have reasonable coverage as part of test_torch.py's TestTensorOp tests, function coverage is spotty. Universal functions are similar enough it should be possible to generate tests for them.

Summary:
Addresses https://github.com/pytorch/pytorch/issues/33300.
Calling .numpy() on a CUDA or non-strided (e.g. sparse) tensor segfaults in current PyTorch. This fixes the segfaults and throws the appropriate TypeError, as was intended.
Two tests, one in test_cuda.py and the other in test_sparse.py, are added to verify the behavior.
