Pull Request resolved: https://github.com/pytorch/pytorch/pull/27782
Warnings show up when running `make html` to build documentation. All of
the warnings are very reasonable and point to bugs in our docs. This PR
attempts to fix most of those warnings.
In the future we will add something to the CI that asserts that there
are no warnings in our docs.
Test Plan: - build and view changes locally

Summary:
Currently when an integral tensor is divided by zero, it emits a
"floating point exception" (which can be different from system to
system). Clarify in the document that nothing would be guaranteed under
this circumstance.

Summary:
Added Complex support with AVX to unary ops and binary ops.
I need to add nan propagation to minimum() and maximum() in the future.
In-tree changes to pytorch to support complex numbers are being submitted here.
Out-of-tree support for complex numbers is here: pytorch-cpu-strided-complex extension
Preliminary Benchmarks are here.
I tried rrii and riri and found that riri is better in most situations.
Divide is very slow because you can't reduce 1/(x+y)
Sqrt is also very slow.
Reciprocal could be sped up after I add conj()
Everything else is typically within 20% of the real number performance.
Questions:
Why does macOS not support mil? #if AT_MKL_ENABLED() && !defined(__APPLE__) in vml.h. MKL does support some complex operations like Abs, so I was curious about trying it.
Is MKL just calling AVX?

Summary:
Changelog:
- Enable broadcasting of RHS and LHS tensors for lu_solve. This means that you can now have RHS with size `3 x 2` and LHS with size `4 x 3 x 3` for instance
- Remove deprecated behavior of having 2D tensors for RHS. Now all tensors have to have a last dimension which equals the number of right hand sides
- Modified docs
Pull Request resolved: https://github.com/pytorch/pytorch/pull/24333
Test Plan: - Add tests for new behavior in test_torch.py with a port to test_cuda.py

Summary:
As in https://github.com/pytorch/pytorch/issues/23439, some descriptions of arguments in `_torch_docs.py` have been replaced by `common_args`, it would be helpful to check if any descriptions can be replaced for new docs in the future.

Summary:
Changelog:
- Add batching for det / logdet / slogdet operations
- Update derivative computation to support batched inputs (and consequently batched outputs)
- Update docs
Pull Request resolved: https://github.com/pytorch/pytorch/pull/22909
Test Plan:
- Add a `test_det_logdet_slogdet_batched` method in `test_torch.py` to test `torch.det`, `torch.logdet` and `torch.slogdet` on batched inputs. This relies on the correctness of `torch.det` on single matrices (tested by `test_det_logdet_slogdet`). A port of this test is added to `test_cuda.py`
- Add autograd tests for batched inputs

Summary:
I manually went through all functions in `torch.*` and corrected any mismatch between the arguments mentioned in doc and the ones actually taken by the function. This fixes https://github.com/pytorch/pytorch/issues/8698.

Summary:
This has been requested in https://github.com/pytorch/pytorch/issues/20323
(It is still not exactly the same as NumPy, which allows you to pass tensors at mean/std and broadcast them with size, but the present PR is extremely simple and does the main thing people are asking for)
