`torch.norm` is very odd. Some notable issues are:
- The default value of `"fro"` in `torch.norm` has an odd behaviour when `dim=None`. This is handled in the new dispatch
- The treatment of the `dtype` argument in `torch.norm` was completely wrong. This should fix it
- Some `out=` variants in the previous implementation were also wrong. This should fix those.
- This new dispatch should make some paths much faster. For example, `torch.norm(x)` where `x` is complex.
I'll try to make the changes in these PRs as incremental as possible as this is a tricky one.

This is a new version of #15648 based on the latest master branch.
Unlike the previous PR where I fixed a lot of the doctests in addition to integrating xdoctest, I'm going to reduce the scope here. I'm simply going to integrate xdoctest, and then I'm going to mark all of the failing tests as "SKIP". This will let xdoctest run on the dashboards, provide some value, and still let the dashboards pass. I'll leave fixing the doctests themselves to another PR.
In my initial commit, I do the bare minimum to get something running with failing dashboards. The few tests that I marked as skip are causing segfaults. Running xdoctest results in 293 failed, 201 passed tests. The next commits will be to disable those tests. (unfortunately I don't have a tool that will insert the `#xdoctest: +SKIP` directive over every failing test, so I'm going to do this mostly manually.)

This reverts commit a58876ace78df1cfeb136cad592487f34d7e02f1.
Reverted https://github.com/pytorch/pytorch/pull/74727 on behalf of https://github.com/seemethere due to Fails internal use cases, might extend out to external use cases as well. Need to assess overall impact of this change more widely
**BC-breaking note**:
This PR deprecates `torch.lu` in favor of `torch.linalg.lu_factor`.
A upgrade guide is added to the documentation for `torch.lu`.
Note this PR DOES NOT remove `torch.lu`.

I figured these out by unconditionally turning on a no-op torch function
mode on the test suite and then fixing errors as they showed up. Here's
what I found:
- _parse_to failed internal assert when __torch_function__'ed because it
claims its name is "to" to the argument parser; added a name override
so we know how to find the correct name
- Infix operator magic methods on Tensor did not uniformly handle
__torch_function__ and TypeError to NotImplemented. Now, we always
do the __torch_function__ handling in
_wrap_type_error_to_not_implemented and your implementation of
__torch_function__ gets its TypeErrors converted to NotImplemented
(for better or for worse; see
https://github.com/pytorch/pytorch/issues/75462 )
- A few cases where code was incorrectly testing if a Tensor was
Tensor-like in the wrong way, now use is_tensor_like (in grad
and in distributions). Also update docs for has_torch_function to
push people to use is_tensor_like.
- is_grads_batched was dropped from grad in handle_torch_function, now
fixed
- Report that you have a torch function even if torch function is
disabled if a mode is enabled. This makes it possible for a mode
to return NotImplemented, pass to a subclass which does some
processing and then pass back to the mode even after the subclass
disables __torch_function__ (so the tensors are treated "as if"
they are regular Tensors). This brings the C++ handling behavior
in line with the Python behavior.
- Make the Python implementation of overloaded types computation match
the C++ version: when torch function is disabled, there are no
overloaded types (because they all report they are not overloaded).

This creates a `histogramdd` operator with overloads matching the `Union`
behaviour used in the functional variant. Moving into C++ is preferred because
it can handle torch function automatically instead of needing to differentiate
between the overloads manually.
This also adds a new return type: `std::tuple<Tensor, std::vector<Tensor>>`. For
which I've updated `wrap` to be completely generic for tuples and removed the
old manual definitions.

I've kept the symbol `torch.functional.istft` because it looks like public API,
but it could just as easily be moved to `_torch_docs.py`.
Moving this into its own PR until TorchScript starts recognizing `input`
as a keyword argument.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/72833Closes#72550
The latest version of librosa breaks backward compatibility in two
ways:
- Everything except the input tensor is now keyword-only
- `pad_mode` now defaults to `'constant'` for zero-padding
https://librosa.org/doc/latest/generated/librosa.stft.html
This changes the test to match the old behaior even when using the new
library and updates the documentation to explicitly say that
`torch.stft` doesn't exactly follow the librosa API. This was always
true (`torch.stft` it has new arguments, a different default window
and supports complex input), but it can't hurt to be explicit.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/66933
This PR exposes `torch.lu` as `torch.linalg.lu_factor` and
`torch.linalg.lu_factor_ex`.
This PR also adds support for matrices with zero elements both in
the size of the matrix and the batch. Note that this function simply
returns empty tensors of the correct size in this case.
We add a test and an OpInfo for the new function.
This PR also adds documentation for this new function in line of
the documentation in the rest of `torch.linalg`.

Summary:
This is step 3/7 of https://github.com/pytorch/pytorch/issues/50276. It only adds support for the argument but doesn't implement new indexing modes yet.
Pull Request resolved: https://github.com/pytorch/pytorch/pull/62722
Test Plan:
Verified this is not FC breaking by adding logging to both meshgrid
overloads and then called meshgrid twice:
`meshgrid(*tensors)`
and
`meshgrid(*tensors, indexing='ij')`
This confirmed that the former signature triggered the original native
function and the latter signature triggered the new native function.

Fixes https://github.com/pytorch/pytorch/issues/62793
This is mostly a quick fix. I think the more correct fix could be updating `unique_dim` to `_unique_dim` which could be BC-breaking for C++ users (� maybe). Maybe something else I am missing.
~~Not sure how to add a test for it.~~ Have tested it locally.
We can add a test like following. Tested this locally, it fails currently but passes with the fix.
```python
def test_wildcard_import(self):
exec('from torch import *')

Summary:
The PR fixes two issues:
- See https://github.com/pytorch/pytorch/issues/62747 and https://github.com/pytorch/audio/issues/1409. The length mismatch when the given ``length`` parameter is longer than expected. Add padding logic in consistent with librosa.
- See https://github.com/pytorch/pytorch/issues/62323. The current implementations checks if the min value of window_envelop.abs() is greater than zero. In librosa they normalize the signal on non-zero values by indexing. Like
```
approx_nonzero_indices = ifft_window_sum > util.tiny(ifft_window_sum)
y[approx_nonzero_indices] /= ifft_window_sum[approx_nonzero_indices]

Summary:
torch.norm has a couple documentation issues, like https://github.com/pytorch/pytorch/issues/44552 and https://github.com/pytorch/pytorch/issues/38595, but since it's deprecated this PR simply clarifies that the documentation (and implementation) of torch.norm maybe be incorrect. This should be additional encouragement for users to migrate to torch.linalg.vector_norm and torch.linalg.matrix_norm.
