Resolves #2700

This effectively calls pyro.enable_validation(__debug__) so that validation is enabled by default unless Python is run in optimized mode (via python -O). This matches the behavior of the assert statement.

I have removed all uses of pyro.enable_validation() from examples and tutorials, since the default behavior is now preferred.

This caught a number of errors in examples and docs; this PR fixes those errors.

  • type error in poutine.scale docs
  • type error in mixed hmm example (as of recent PyTorch version)
  • shape error in eight_schoos/svi.py

@neerajprad this line changes the default behavior of torch.distributions. It may lead to weird behavior since simply importing Pyro will turn on PyTorch validation. However this still seems like the best option to me.

The change looks good to me. My only minor concern would be that some users may find their earlier models slow down when they update Pyro, and might not know that they need to turn off validation explicitly to get the earlier behavior. This is more of an awareness problem that we can address as we go along. This will be a net benefit for our users, specially new ones. We should definitely highlight this in our changelog/release notes.

Summary:
Fixes #47123
Follows pyro-ppl/pyro#2701

This turns on `Distribution` validation by default. The motivation is to favor beginners by providing helpful error messages. Advanced users focused on speed can disable validation by calling
```py
torch.distributions.Distribution.set_default_validate_args(False)
```
or by disabling individual distribution validation via `MyDistribution(..., validate_args=False)`.

In practice I have found many beginners forget or do not know about validation. Therefore I have [enabled it by default](pyro-ppl/pyro#2701) in Pyro. I believe PyTorch could also benefit from this change. Indeed validation caught a number of bugs in `.icdf()` methods, in tests, and in PPL benchmarks, all of which have been fixed in this PR.

## Release concerns
- This may slightly slow down some models. Concerned users may disable validation.
- This may cause new `ValueErrors` in models that rely on unsupported behavior, e.g. `Categorical.log_prob()` applied to continuous-valued tensors (only {0,1}-valued tensors are supported).

We should clearly note this change in release notes.

Added linalg.inv (#48261)

Summary:
This PR adds `torch.linalg.inv` for NumPy compatibility.

`linalg_inv_out` uses in-place operations on provided `result` tensor.

I modified `apply_inverse` to accept tensor of Int instead of std::vector, that way we can write a function similar to `linalg_inv_out` but removing the error checks and device memory synchronization.

I fixed `lda` (leading dimension parameter which is max(1, n)) in many places to handle 0x0 matrices correctly.
Zero batch dimensions are also working and tested.

This PR adds the support for {input/output}_quantized_idxs for standalone module.

if input_quantized_idxs = [] and output_quantized_idxs = [], the standalone module will be expecting float
input and produce float output, and will quantize the input and dequantize output internally

if input_quantized_idxs = [0] and otuput_qiuantized_idxs = [0], the standalone module will be expecting quantized
input and produce quantized output, the input will be quantized in the parent module, and output will be dequantized
in the parent module as well, this is similar to current quantized modules like nn.quantized.Conv2d

[numpy] `torch.digamma` : promote integer inputs to float (#48302)

Summary:
**BC-breaking Note:**

This PR updates PyTorch's digamma function to be consistent with SciPy's special.digamma function. This changes the result of the digamma function on the nonpositive integers, where the gamma function is not defined. Since the gamma function is undefined at these points, the (typical) derivative of the logarithm of the gamma function is also undefined at these points, and for negative integers this PR updates digamma to return NaN. For zero, however, it returns -inf to be consistent with SciPy.

Interestingly, SciPy made a similar change, which was noticed by at least one user: https://github.com/scipy/scipy/issues/9663#issue-396587679.

SciPy's returning of negative infinity at zero is intentional:
https://github.com/scipy/scipy/blob/59347ae8b86bcc92c339efe213128f64ab6df98c/scipy/special/cephes/psi.c#L163

This change is consistent with the C++ standard for the gamma function:

[*.py] Rename "Arguments:" to "Args:" (#49736)

Summary:
I've written custom parsers and emitters for everything from docstrings to classes and functions. However, I recently came across an issue when I was parsing/generating from the TensorFlow codebase: inconsistent use of `Args:` and `Arguments:` in its docstrings.

```sh
(pytorch#c348fae)$ for name in 'Args:' 'Arguments:'; do
    printf '%-10s %04d\n' "$name" "$(rg -IFtpy --count-matches "$name" | paste -s -d+ -- | bc)"; done
Args:      1095
Arguments: 0336
```

It is easy enough to extend my parsers to support both variants, however it looks like `Arguments:` is wrong anyway, as per:

  - https://google.github.io/styleguide/pyguide.html#doc-function-args @ [`ddccc0f`](https://github.com/google/styleguide/blob/ddccc0f/pyguide.md)

  - https://chromium.googlesource.com/chromiumos/docs/+/master/styleguide/python.md#describing-arguments-in-docstrings @ [`9fc0fc0`](https://chromium.googlesource.com/chromiumos/docs/+/9fc0fc0/styleguide/python.md)

  - https://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html @ [`c0ae8e3`](https://github.com/sphinx-contrib/napoleon/blob/c0ae8e3/docs/source/example_google.rst)

Therefore, only `Args:` is valid. This PR replaces them throughout the codebase.

# This is the commit message #39:

Implement torch.linalg.qr (#47764)

Summary:
I am opening this PR early to have a place to discuss design issues.
The biggest difference between `torch.qr` and `numpy.linalg.qr` is that the former `torch.qr` takes a boolean parameter `some=True`, while the latter takes a string parameter `mode='reduced'` which can be one of the following:

`reduced`
this is completely equivalent to `some=True`, and both are the default.

`complete`
this is completely equivalent to `some=False`.

`r`
this returns only `r` instead of a tuple `(r, q)`. We have already decided that we don't want different return types depending on the parameters, so I propose to return `(r, empty_tensor)` instead. I **think** that in this mode it will be impossible to implement the backward pass, so we should raise an appropriate error in that case.

`raw`
in this mode, it returns `(h, tau)` instead of `(q, r)`. Internally, `h` and `tau` are obtained by calling lapack's `dgeqrf` and are later used to compute the actual values of `(q, r)`. The numpy docs suggest that these might be useful to call other lapack functions, but at the moment none of them is exposed by numpy and I don't know how often it is used in the real world.
I suppose the implementing the backward pass need attention to: the most straightforward solution is to use `(h, tau)` to compute `(q, r)` and then use the normal logic for `qr_backward`, but there might be faster alternatives.

`full`, `f`
alias for `reduced`, deprecated since numpy 1.8.0

`economic`, `e`
similar to `raw but it returns only `h` instead of `(h, tau). Deprecated since numpy 1.8.0

To summarize:
  * `reduce`, `complete` and `r` are straightforward to implement.

  * `raw` needs a bit of extra care, but I don't know how much high priority it is: since it is used rarely, we might want to not support it right now and maybe implement it in the future?

  * I think we should just leave `full` and `economic` out, and possibly add a note to the docs explaining what you need to use instead

Fix a KaTeX crash and many docstring issues (#49684)

Summary:
The first commit fixes the `MultiheadAttention` docstrings, which are causing a cryptic KaTeX crash.

The second commit fixes many documentation issues in `torch/_torch_docs.py`, and closes gh-43667 (missing "Keyword arguments" headers). It also fixes a weird duplicate docstring for `torch.argmin`; there's more of these, it looks like they were written based on whether the C++ implementation has an overload. That makes little sense to a Python user though, and the content is simply duplicate.

The `Shape:` heading for https://pytorch.org/docs/master/generated/torch.nn.MultiheadAttention.html looked bad, here's what it looks like with this PR:

[quant] Quantizable LSTM (#49671)

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49671

- Introduces the `torch.nn.quantizable` namespace
- Adds the `torch.nn.quantizable.LSTM` module

The point of the `quantizable` namespace is to segregate the purely quantized modules with the modules that could be quantized through a normal quantization flow, but are not using the quantized kernels explicitly.
That means the quantizable modules are functionally and numerically equivalent to the FP ones and can be used instead of the FP ones without any loss.

The main difference between the `torch.nn.LSTM` and the `torch.nn.quantizable.LSTM` is that the former one does not support observation for the linear layers, because all the computation is internal to the `aten` namespace.
The `torch.nn.quantizable.LSTM`, however, uses explicit linear layers that can be observed for further quantization.

Making ops c10-full: list of optional tensors (#49138)

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49138

See for details: https://fb.quip.com/QRtJAin66lPN

We need to model optional types explicitly, mostly for schema inference. So we cannot pass a `Tensor?[]` as `ArrayRef<Tensor>`, instead we need to pass it as an optional type. This PR changes it to `torch::List<c10::optional<Tensor>>`. It also makes the ops c10-full that were blocked by this.

## Backwards Compatibility

- This should not break the Python API because the representation in Python is the same and python_arg_parser just transforms the python list into a `List<optional<Tensor>>` instead of into a `List<Tensor>`.
- This should not break serialized models because there's some logic that allows loading a serialized `List<Tensor>` as `List<optional<Tensor>>`, see https://github.com/pytorch/pytorch/pull/49138/files#diff-9315f5dd045f47114c677174dcaa2f982721233eee1aa19068a42ff3ef775315R57
- This will break backwards compatibility for the C++ API. There is no implicit conversion from `ArrayRef<Tensor>` (which was the old argument type) to `List<optional<Tensor>>`. One common call pattern is `tensor.index({indices_tensor})`, where indices_tensor is another `Tensor`, and that will continue working because the `{}` initializer_list constructor for `List<optional<Tensor>>` can take `Tensor` elements that are implicitly converted to `optional<Tensor>`, but another common call pattern was `tensor.index(indices_tensor)`, where previously, the `Tensor` got implicitly converted to an `ArrayRef<Tensor>`, and to implicitly convert `Tensor -> optional<Tensor> -> List<optional<Tensor>>` would be two implicit conversions. C++ doesn't allow chaining. two implicit conversions. So those call sites have to be rewritten to `tensor.index({indices_tensor})`.

Summary:
We recently (https://github.com/pytorch/pytorch/issues/7582) dropped magma v1 support, but we were still including the legacy compatibility headers and using functions only provided by them.
This changes the includes to the new magma_v2 header and fixes the triangular solve functions to use the v2-style magma_queue-using API.

Tighten up error checking on manual_kernel_registration (#49341)

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49341

I noticed that #49097 was using manual_kernel_registration incorrectly,
so this diff tightens up the testing so that:

1. We don't generate useless wrapper functions when manual_kernel_registration
is on (it's not going to be registered, so it does nothing).

2. manual_kernel_registration shouldn't affect generation of functions in
Functions.h; if you need to stop bindings, use manual_cpp_binding

3. Structured and manual_kernel_registration are a hard error

4. We raise an error if you set dispatch and manual_kernel_registration at the
same time.

I also fixed one case of confusion where defn() was used to define a decl().
If you want to define a declaration with no defaults, say no_default().decl()
which is more direct and will give us code reviewers a clue if you should
have pushed this logic in.

torch.xlogy: Use wrapped_scalar_tensor / gpu_with_scalars to speed up GPU kernel. (#49926)

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49926

While investigating https://github.com/pytorch/pytorch/issues/49758, I changed the xlogy kernel to use the recommended wrapped_scaler_tensor pattern instead of moving the scalar to the GPU as a tensor.
While this doesn't avoid a synchronization (there is no synchronization in the move, as its done via fill), this does significantly speed up the GPU kernel (almost ~50%, benchmark in PR comments).

From looking at the nvprof output, it looks like this code path avoids broadcasting.  Aside: this seems unnecessary, as there is nothing special from the point-of-view of broadcasting whether the Tensor
is ()-sized or marked as a wrapped_scalar.  Still, this is a useful change to make as we avoid extra kernel launches and dispatches to create and fill the tensor.

Suppress "statement is unreachable" warning (#49495)

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49495

Compiling PyTorch currently generates a large number of warnings like this:
```
caffe2/aten/src/ATen/core/builtin_function.h(105): warning: statement is unreachable
```
The offending code
```
  std::string pretty_print_schema() const override {
    TORCH_INTERNAL_ASSERT(false);
    return "";
  }
```
has an unreachable return which prevents a "no return" warning.

We resolve the situation by using NVCC's pragma system to suppress this warning within this function.

Test Plan:
The warning appears when running:
```
buck build mode/dev-nosan //caffe2/torch/fb/sparsenn:test
```
As well as a number of other build commands.

Ensures that having a Tensor with 0 elements does not crash observers.
Note: it's illegal to pass Tensors with 0 elements to reductions such

quant: throw a nice error message for allclose with quantized inputs (#49802)

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49802

Currently `torch.allclose` is not supported with quantized inputs.
Throw a nice error message instead of a cryptic one.

Test Plan:
```
torch.allclose(x_fp32, y_fp32)

torch.allclose(x_int8, y_int8)
```

Unfortunately I cannot repro this inside the PyTorch module, but the issue
author has a good point and and we should not mutate the dict inside
of the iteration.

[JIT] Remove buffer metadata serialization forward-compat gate (#49990)

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49990

**Summary**
This commit removes the forward-compatibility gate for buffer metadata
serialization. It was introduced to allow versions of fbcode
binaries statically linked against older versions of PyTorch (without
buffer metadata in JIT) to deserialize archives produced by new versions
of PyTorch. Enough time has probably passed that these old binaries
don't exist anymore, so it should be safe to remove the gate.

**Test Plan**
Internal tests.

Fix store based barrier to only use 'add'. (#49930)

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49930

Certain store implementations don't work well when we use get() and
add() on the same key. To avoid this issue, we only use add() in the store
based barrier. The buggy store implementations can't be properly fixed due to
legacy reasons.

Test Plan:
1) unit tests.
2) waitforbuildbot

[caffe2][a10] Move down pragma pop to properly suppress warning 4522 (#49233)

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49233

As the comments on line 160, say we should suppress this overly aggressive warning with MSVC:
```
caffe2\tensorbody.h_ovrsource#header-mode-symlink-tree-only,headers\aten\core\tensorbody.h(1223): warning C4522: 'at::Tensor': multiple assignment operators specified
```

However, in order to remove the warning, the closing brace of the class must be between the`#pragma warning` push and its corresponding pop. Move the pop down to ensure that.

Test Plan: Built locally using clang for Windows without buck cache, confirmed the warning resolved

Enable distribution validation if __debug__ (#48743)

Summary:
Fixes https://github.com/pytorch/pytorch/issues/47123
Follows https://github.com/pyro-ppl/pyro/pull/2701

This turns on `Distribution` validation by default. The motivation is to favor beginners by providing helpful error messages. Advanced users focused on speed can disable validation by calling
```py
torch.distributions.Distribution.set_default_validate_args(False)
```
or by disabling individual distribution validation via `MyDistribution(..., validate_args=False)`.

In practice I have found many beginners forget or do not know about validation. Therefore I have [enabled it by default](https://github.com/pyro-ppl/pyro/pull/2701) in Pyro. I believe PyTorch could also benefit from this change. Indeed validation caught a number of bugs in `.icdf()` methods, in tests, and in PPL benchmarks, all of which have been fixed in this PR.

## Release concerns
- This may slightly slow down some models. Concerned users may disable validation.
- This may cause new `ValueErrors` in models that rely on unsupported behavior, e.g. `Categorical.log_prob()` applied to continuous-valued tensors (only {0,1}-valued tenso…
