41e7e1bc40 Rename potrs to cholesky_solve (#15334)
Summary:
Changelog:
- Renames `potrs` to `cholesky_solve` to remain consistent with Tensorflow and Scipy (not really, they call their function chol_solve)
- Default argument for upper in cholesky_solve is False. This will allow a seamless interface between `cholesky` and `cholesky_solve`, since the `upper` argument in both function are the same.
- Rename all tests
- Create a tentative alias for `cholesky_solve` under the name `potrs`, and add deprecated warning to not promote usage.

5837320b70 Add script standard library documentation + cleanup (#14912)
Summary:
Documents what is supported in the script standard library.

* Adds `my_script_module._get_method('forward').schema()` method to get function schema from a `ScriptModule`
* Removes `torch.nn.functional` from the list of builtins. The only functions not supported are `nn.functional.fold` and `nn.functional.unfold`, but those currently just dispatch to their corresponding aten ops, so from a user's perspective it looks like they work.
* Allow printing of `IValue::Device` by getting its string representation

5d3a347685 Stashing checkpointing RNG states based on devices of arg tensors (#14518)
Summary:
This PR intends to address apaszke's concerns in https://github.com/pytorch/pytorch/pull/14253#issuecomment-441740016.  Preserving the rng state is now controlled by a kwarg rather than a global state, hopefully in a python 2.7-compatible way.

Additionally, the checkpointing function stashes and restores the RNG states of
1. devices associated with all input tensor args to run_fn as well as
2. the current device.

I could easily change this to only save and restore the RNG states associated 1. alone.  This would simplify the logic to create a [deduplicated, ordered](https://github.com/pytorch/pytorch/compare/master...mcarilli:checkpointing_rng_touchup?expand=1#diff-58da227fc9b1d56752b7dfad90428fe0R37) list of devices considered active.

I'm wondering if the [get_device_states](https://github.com/pytorch/pytorch/compare/master...mcarilli:checkpointing_rng_touchup?expand=1#diff-58da227fc9b1d56752b7dfad90428fe0R32) and [set_device_states](https://github.com/pytorch/pytorch/compare/master...mcarilli:checkpointing_rng_touchup?expand=1#diff-58da227fc9b1d56752b7dfad90428fe0R47) functions are general enough to reside elsewhere (presumably torch/random.py).  I'm also wondering if the check on [torch.cuda._initialized](https://github.com/pytorch/pytorch/compare/master...mcarilli:checkpointing_rng_touchup?expand=1#diff-58da227fc9b1d56752b7dfad90428fe0R47) would be better placed within `get_device_states`.

2d3cf98b49 Making dist.get_default_group private for PT1 release (#14767)
Summary:
When I wrote the frontend API, it is designed on not letting users use the default_group directly on any functions.  It should really be private.

All collectives are supposed to either use group.WORLD, or anything that comes out of new_group. That was the initial design.

We need to make a TODO on removing group.WORLD one day. It exists for backward compatibility reasons and adds lots of complexity.

f80d34a1c8 Update Tensor doc (#14339)
Summary:
Add to the Tensor doc info about `.device`, `.is_cuda`, `.requires_grad`, `.is_leaf` and `.grad`.
Update the `register_backward_hook` doc with a warning stating that it does not work in all cases.
Add support in the `_add_docstr` function to add docstring to attributes.

There is an explicit cast here but I am not sure how to handle it properly. The thing is that the doc field for getsetdescr is written as being a const char * (as all other doc fields in descriptors objects) in cpython online documentation. But in the code, it is the only one that is not const.
I assumed here that it is a bug in the code because it does not follow the doc and the convention of the others descriptors and so I cast out the const.
EDIT: the online doc I was looking at is for 3.7 and in that version both the code and the doc are const. For older versions, both are non const.
Please let me know if this should not be done. And if it should be done if there is a cleaner way to do it !

be7c618fd7 torch.sparse.sum() (#12430)
Summary:
- to fix #12241
- add `_sparse_sum()` to ATen, and expose as `torch.sparse.sum()`, not support `SparseTensor.sum()` currently
- this PR depends on #11253, and will need to be updated upon it lands
- [x] implement forward
- [x] implement backward
- performance [benchmark script](https://gist.github.com/weiyangfb/f4c55c88b6092ef8f7e348f6b9ad8946#file-sparse_sum_benchmark-py):
  - sum all dims is fastest for sparse tensor
  - when input is sparse enough nnz = 0.1%, sum of sparse tensor is faster than dense in CPU, but not necessary in CUDA
  - CUDA backward is comparable (<2x) between `sum several dims` vs `sum all dims` in sparse
  - CPU backward uses binary search is still slow in sparse, takes `5x` time in `sum [0, 2, 3] dims` vs `sum all dims`
    - optimize CUDA backward for now
      - using thrust for sort and binary search, but runtime not improved
  - both of CPU and CUDA forward are slow in sparse (`sum several dims` vs `sum all dims`), at most `20x` slower in CPU, and `10x` in CUDA
    - improve CPU and CUDA forward kernels

- after improving CPU and CUDA forward kernels
  - in `(1000,   [1000, 1000, 2, 2], [0, 2, 3], False, sumD)` forward, CPU takes ~~`171 µs`~~, in which `130 µs` is spent on `coalesce()`, for CUDA, total time is ~~`331 µs`~~, in which `141 µs` is spent on `coalesce()`, we need to reduce time at other places outside `coalesce()`.
  - after a few simple tweaks, now in the forward, it is at most `10x` slower in CPU, and `7x` in CUDA. And time takes in `sum dense dims only [2, 3]` is `~2x` of `sum all dims`. Speed of `sum all sparse dims [0, 1]` is on bar with `sum all dims`

- time takes in CUDA backward of sparse is super long with large variance (in case of nnz=10000, it normally takes 6-7ms). To improve backward of sparse ops, we will need to debug at places other than CUDA kernels. here is a benchmark of `torch.copy_()`:
```
>>> d = [1000, 1000, 2, 2]
>>> nnz = 10000
>>> I = torch.cat([torch.randint(0, d[0], size=(nnz,)),
               torch.randint(0, d[1], size=(nnz,))], 0).reshape(2, nnz)
>>> V = torch.randn(nnz, d[2], d[3])
>>> size = torch.Size(d)
>>> S = torch.sparse_coo_tensor(I, V, size).coalesce().cuda()
>>> S2 = torch.sparse_coo_tensor(I, V, size).coalesce().cuda().requires_grad_()
>>> data = S2.clone()
>>> S.copy_(S2)
>>> y = S * 2
>>> torch.cuda.synchronize()
>>> %timeit y.backward(data, retain_graph=True); torch.cuda.synchronize()
7.07 ms ± 3.06 ms per loop (mean ± std. dev. of 7 runs, 1000 loops each)

c36156eded Option to preserve bitwise accuracy of gradient checkpointed vs non-checkpointed dropout (#14253)
Summary:
This issue was noticed, and fix proposed, by raulpuric.

Checkpointing is implemented by rerunning a forward-pass segment for each checkpointed segment during backward.  This can result in the RNG state advancing more than it would without checkpointing, which can cause checkpoints that include dropout invocations to lose end-to-end bitwise accuracy as compared to non-checkpointed passes.

The present PR contains optional logic to juggle the RNG states such that checkpointed passes containing dropout achieve bitwise accuracy with non-checkpointed equivalents.**  The user requests this behavior by supplying `preserve_rng_state=True` to `torch.utils.checkpoint` or `torch.utils.checkpoint_sequential`.

Currently, `preserve_rng_state=True` may incur a moderate performance hit because restoring MTGP states can be expensive.  However, restoring Philox states is dirt cheap, so syed-ahmed's [RNG refactor](https://github.com/pytorch/pytorch/pull/13070#discussion_r235179882), once merged, will make this option more or less free.

I'm a little wary of the [def checkpoint(function, *args, preserve_rng_state=False):](https://github.com/pytorch/pytorch/pull/14253/files#diff-58da227fc9b1d56752b7dfad90428fe0R75) argument-passing method (specifically, putting a kwarg after a variable argument list).  Python 3 seems happy with it.
Edit:  It appears Python 2.7 is NOT happy with a [kwarg after *args](https://travis-ci.org/pytorch/pytorch/builds/457706518?utm_source=github_status&utm_medium=notification).  `preserve_rng_state` also needs to be communicated in a way that doesn't break any existing usage.  I'm open to suggestions (a global flag perhaps)?

**Batchnorm may still be an issue, but that's a battle for another day.

5dd153b1c2 speed up torch.sparse_mask() cpu kernel (#13290)
Summary:
- `sparse_mask(D, S)` is useful to implement backward for `sparse_addmm()`
- previous `sparse_mask(D, S)` cpu kernel is not parallelized
- this PR speed up the cpu kernel for two separated cases:
  - `D.dim == S.sparse_dim`: simply parallelize the kernel
  - `D.dim > S.sparse_dim`: simply use CUDA kernel implementation
- performance:

`D.dim == S.sparse_dim`
```
>>> nnz = 100000
>>> dims = [1000, 1000]
>>> I = torch.cat([torch.randint(0, dims[0], size=(nnz,)),

>>> V = torch.randn(nnz)
>>> size = torch.Size(dims)

>>> S = torch.sparse_coo_tensor(I, V, size).coalesce()
>>> D = torch.randn(dims)

4a3baec961 Hub Implementation (#12228)
Summary:
[Edit: after applied colesbury 's suggestions]
* Hub module enable users to share code + pretrained weights through github repos.
Example usage:
```
hub_model = hub.load(
     'ailzhang/vision:hub', # repo_owner/repo_name:branch
     'wrapper1', # entrypoint
      1234, # args for callable [not applicable to resnet18]
      pretrained=True) # kwargs for callable
```
* Protocol on repo owner side: example https://github.com/ailzhang/vision/tree/hub
     * The "published" models should be at least in a branch/tag. It can't be a random commit.
     * Repo owner should have the following field defined in `hubconf.py`
        * function/entrypoint with function signature `def wrapper1(pretrained=False, *args, **kwargs):`
        * `pretrained` allows users to load pretrained weights from repo owner.
        * `args` and `kwargs` are passed to the callable `resnet18`, repo owner should clearly specify their help message in the docstring

```
def wrapper1(pretrained=False, *args, **kwargs):
    """
    pretrained (bool): a recommended kwargs for all entrypoints
    args & kwargs are arguments for the function
    """
    from torchvision.models.resnet import resnet18
    model = resnet18(*args, **kwargs)
    checkpoint = 'https://download.pytorch.org/models/resnet18-5c106cde.pth'
    if pretrained:
        model.load_state_dict(model_zoo.load_url(checkpoint, progress=False))
    return model
```
* Hub_dir
    * `hub_dir` specifies where the intermediate files/folders will be saved. By default this is `~/.torch/hub`.
    * Users can change it by either setting the environment variable `TORCH_HUB_DIR` or calling `hub.set_dir(PATH_TO_HUB_DIR)`.
    * By default, we don't cleanup files after loading so that users can use cache next time.

* Cache logic :
    * We used the cache by default if it exists in `hub_dir`.
    * Users can force a fresh reload by calling `hub.load(..., force_reload=True)`.

c2f8f5076c add narrow() support for sparse tensors re: #8853 (#11342)
Summary:
Couple questions:

1) I used the log1p implementation in #8969 as a guide especially for testing.  I'm not sure what the ```skipIfROCM``` annotation is for, so unsure if i need it for my test.

2) I implemented the branching logic in the narrow function itself; is this the right place to do so?  I noticed that there a number of places where sparse-specific logic is handled with just an if statement in this file.  Or should I implement a separate dispatch in native_functions.yml as in the log1p?

And of course, happy to make any any other updates/changes that I may have missed as well.  This is my first PR to the project.
