`torch.isclose` does not do this bool tensors, which results in a test failure since subtraction (`abs(actual - expected)`) is not supported for them (see #58981). Since the `dtype` is already checked at this point, we can safely move the upcasting before `torch.isclose` is invoked.

Before we only tested that the correct error message is returned if `msg` is passed as callable. This adds tests that make sure that
- the inputs passed to the callable are the same inputs passed to `torch.assert_close` and
- the `diagnostics` namespace has the same attributes and types as documented.

Changes to the default error message in case of mismatching values need to be reflected in the examples given in the docstring. Normally this should be enforced by a [`doctest`](https://docs.python.org/3/library/doctest.html). mruberry do you know why we don't have such a check?

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/60091Closes#58383. (1) and (2) are implemented. (3) was rejected. No consensus was reached on (4) and (5).
Improvements:
- Instead of calling everything "Tensors" we now use "Scalars" and "Tensor-likes" depending on the shape. Plus, we now internally have the option to adapt this identifier for example to report "Imaginary components of complex tensor-likes", which is even more expressive.
- The reported conditions "not close" and "not equal" are now determined based on `rtol` and `atol`.
- The number of mismatched elements and the offending indices are only reported in case the inputs are not scalar
- The allowed `rtol` and `atol` is only reported if `> 0`

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/58918
~Instead of a distinct `torch.testing.assert_close` and `torch.testing.assert_equal`, this makes `torch.testing.assert_equal` a special case of `torch.testing.assert_close` for `rtol=atol=0`. In this case the closeness definition `abs(actual - expected) <= atol + rtol * abs(expected)` boils down to `abs(actual - expected) <= 0`. Since `abs(x)` can never be `<0`, this is equivalent to `abs(a - b) == 0` and this again boils down to `a == b`.~
Following https://github.com/pytorch/pytorch/pull/58918#issuecomment-860642057 and some offline discussions, we opted to use `assert_equal` as an example how to `partial` it.
This makes maintaing the module a lot easier, because we don't need to keep two functions in sync.

Currently all values are used for the reported absolute and relative differences. This usually works fine, but breaks down for the extremals:
```python
torch.testing.assert_close(torch.tensor([1.0, 0.0]), torch.tensor([2.0, 0.0]))
```
```
[...]
Greatest absolute difference: 1.0 at 0 (up to 1e-05 allowed)
Greatest relative difference: nan at 1 (up to 1.3e-06 allowed)
```
Although the second element is matching it is listed as offender for the greatest relative difference. The `NaN` stems from the `0 / 0` division.
To overcome this, we should only use the values that were considered a mismatch for the reported stats.

Summary:
Currently we require type equality for `torch.testing.assert_(equal|close)`:
3db45bcb91/torch/testing/_asserts.py (L509-L513)
That means `assert_equal(1, 1.0)` will correctly fail. Although the type of a scalar is similiar to a dtype of a tensor, `assert_equal(1, 1.0, check_dtype=False)` will also fail while `assert_equal(torch.as_tensor(1), torch.as_tensor(1.0), check_dtype=False)` will pass.
To make the interface more consistent, this PR relaxes the type equality constraint, by disabling it in case both inputs are scalars.

Proof-of-concept for https://github.com/pytorch/pytorch/pull/55145#issuecomment-817297273
With this the user is able to pass a custom error message to `assert_(equal|close)` which will be used in case the values mismatch. Optionally, a callable can be passed which will be called with mismatch diagnostics and should return an error message:
```python
def make_msg(a, b, info):
return (
f"Argh, we found {info.total_mismatches} mismatches! "
f"That is {info.mismatch_ratio:.1%}!"
)
torch.testing.assert_equal(torch.tensor(1), torch.tensor(2), msg=make_msg)
```
If you imagine `a` and `b` as the outputs of binary ufuncs, the error message could look like this:
```python
def make_msg(input, torch_output, numpy_output, info):
return (
f"For input {input} torch.binary_op() and np.binary_op() do not match: "
f"{torch_output} != {numpy_output}"
)
torch.testing.assert_equal(
torch.binary_op(input),
numpy.binary_op(input),
msg=lambda a, b, info: make_msg(input, a, b, info),
)
```
This should make it much easier for developers to find out what is actually going wrong.

Repeating the discussion from https://github.com/pytorch/pytorch/pull/54784#issuecomment-811792089
The error messages for mismatched values are directly adapted from the old `_compare_tensors_internal`:
50cb75edce/torch/testing/__init__.py (L104-L111)
A sample error message right now looks like this
```
With rtol=1.3e-06 and atol=1e-05, found 1 different element(s) out of 12 (8.3%). The greatest difference of 4.0 (5.0 vs. 9.0) occurred at index (2, 3)
```
Using the same data with `numpy.testing.assert_equal` gives the following output:
```
Not equal to tolerance rtol=1.3e-06, atol=1e-05
Mismatched elements: 1 / 12 (8.33%)
Max absolute difference: 4.
Max relative difference: 0.44444445
x: array([[5., 5., 5., 5.],
[5., 5., 5., 5.],
[5., 5., 5., 5.]], dtype=float32)
y: array([[5., 5., 5., 5.],
[5., 5., 5., 5.],
[5., 5., 5., 9.]], dtype=float32)
```
Pros:
- The info is presented in a list instead of a sentence. IMO this makes it more readable
- The maximum relative difference is reported, which is beneficial in case a comparison fails due to the `rtol`
Cons:
- The values of the inputs are reported (this can be disabled by passing `verbose=False`, but lets face it: most users will use the default setting). In case the inputs are large, the output gets truncated with `...`. Not only is it hard to visually find the mismatching values, they could also live within the truncated part, making the output completely useless.
- Even when visually find the offending values it is hard to parse this back to the index in the inputs.
This implements a mix of both to get a short but expressive message:
```
Tensors are not close according to rtol=1.3e-6 and atol=1e-05:
Mismatched elements: 1 / 12 (8.3%)
Max. rel. diff.: 4.44e-1 at (2, 3)
Max. abs. diff.: 4.0 at (2, 3)

Summary:
This is an initial attempt in refactoring and consolidating our S3 read logic for print_test_stats.py, test_history.py, and run_test.py. This way, boto3 and botocore do not need to be imported in various places throughout the code base, and duplicated logic (such as the many type definitions) can exist in one place: `tools/stat_utils/s3_stat_parser.py`. walterddr contributed to this PR by moving print_test_stats.py to the tools folder and the corresponding tests a subfolder within tools.
**NOTE: this removes those tests from CI as the new `tools/test/test_stats.py` is not in the test/ directory as the other tests in TESTS in run_test.py.**
Pull Request resolved: https://github.com/pytorch/pytorch/pull/53755
Test Plan:
This refactoring change should not break anything, so running the files as before should work as they did previously.
To make sure that print_test_stats.py still functions: run `python tools/test/test_stats.py` and make sure all tests pass.
To make sure that test_history.py works, run the example commands from `tools/test_history.py --help` and check that their output matches that shown. Note that the script will continue printing for a while, so don't be alarmed.
Some next steps:
- Actually coming up with similarities among the three current use cases and further refactoring/consolidating of functions (e.g., combining simplify and get_cases)
- Moving more parsing logic to s3_stat_parser.py to have better abstraction between our files
- Adding tests for s3_stat_parser.py when there is more functionality in it

Summary:
We want to store the file names that triggers each test suite so that we can use this data for categorizing those test files.
~~After considering several solutions, this one is the most backwards compatible, and the current test cases in test_testing.py for print test stats don't break.~~
The previous plan did not work, as there are multiple Python test jobs that spawn the same suites. Instead, the new S3 format will store test files (e.g., `test_nn` and `distributed/test_distributed_fork`) which will contain the suites they spawn, which will contain the test cases run within the suite. (Currently, there is no top layer of test files.)
Because of this major structural change, a lot of changes have now been made (thank you samestep!) to test_history.py and print_test_stats.py to make this new format backwards compatible.
Old test plan:
Make sure that the data is as expected in S3 after https://github.com/pytorch/pytorch/pull/52873 finishes.

Summary:
This is a follow up on https://github.com/pytorch/pytorch/issues/49869.
Previously CUDA early termination only happens for generic test classes that extends from `DeviceTypeTestBase`. However, JIT test cases which extends from common_utils.TestCase cannot benefit from the early termination.
This change moves the early termination logic into common_utils.TestCase class.
- all tests extended from common_utils.TestCase now should early terminate if CUDA assert occurs.
- For TestCases that extends from common_device_type.DeviceTypeTestBase, still only do torch.cuda.synchronize() when RTE is thrown.
- For TestCases extends common_utils.TestCase, regardless of whether a test case uses GPU or not, it will always synchronize CUDA as long as `torch.cuda.is_initialize()` returns true.
- Disabling this on common_distributed.py

This is a followup to https://github.com/pytorch/pytorch/issues/49190. Vaguely speaking, the goals are to make it easy to identify test time regressions introduced by PRs. Eventually the hope is to use this information to edit Dr CI comments, but this particular PR just does the analysis and prints it to stdout, so a followup PR would be needed to edit the actual comments on GitHub.
**Important:** for uninteresting reasons, this PR moves the `print_test_stats.py` file.
- *Before:* `test/print_test_stats.py`
- *After:* `torch/testing/_internal/print_test_stats.py`
Notes on the approach:
- Just getting the mean and stdev for the total job time of the last _N_ commits isn't sufficient, because e.g. if `master` was broken 5 commits ago, then a lot of those job times will be much shorter, breaking the statistics.
- We use the commit history to make better estimates for the mean and stdev of individual test (and suite) times, but only when the test in that historical commit is present and its status matches that of the base commit.
- We list all the tests that were removed or added, or whose status changed (e.g. skipped to not skipped, or vice versa), along with time (estimate) info for that test case and its containing suite.
- We don't list tests whose time changed a lot if their status didn't change, because there's a lot of noise and it's unclear how to do that well without too many false positives.
- We show a human-readable commit graph that indicates exactly how many commits are in the pool of commits that could be causing regressions (e.g. if a PR has multiple commits in it, or if the base commit on `master` doesn't have a report in S3).
- We don't show an overall estimate of whether the PR increased or decreased the total test job time, because it's noisy and it's a bit tricky to aggregate stdevs up from individual tests to the whole job level. This might change in a followup PR.
- Instead, we simply show a summary at the bottom which says how many tests were removed/added/modified (where "modified" means that the status changed), and our best estimates of the mean times (and stdevs) of those changes.
- Importantly, the summary at the bottom is only for the test cases that were already shown in the more verbose diff report, and does not include any information about tests whose status didn't change but whose running time got much longer.
Pull Request resolved: https://github.com/pytorch/pytorch/pull/50171
Test Plan:
To run the unit tests:
```
$ python test/test_testing.py
$ python test/print_test_stats.py
```
To verify that this works, check the [CircleCI logs](https://app.circleci.com/pipelines/github/pytorch/pytorch/258628/workflows/9cfadc34-e042-485e-b3b3-dc251f160307) for a test job run on this PR; for example:
- pytorch_linux_bionic_py3_6_clang9_test
To test locally, use the following steps.
First run an arbitrary test suite (you need to have some XML reports so that `test/print_test_stats.py` runs, but we'll be ignoring them here via the `--use-json` CLI option):
```
$ DATA_DIR=/tmp
$ ARBITRARY_TEST=testing
$ python test/test_$ARBITRARY_TEST.py --save-xml=$DATA_DIR/test/test_$ARBITRARY_TEST
```
Now choose a commit and a test job (it has to be on `master` since we're going to grab the test time data from S3, and [we only upload test times to S3 on the `master`, `nightly`, and `release` branches](https://github.com/pytorch/pytorch/pull/49645)):
```
$ export CIRCLE_SHA1=c39fb9771d89632c5c3a163d3c00af3bef1bd489
$ export CIRCLE_JOB=pytorch_linux_bionic_py3_6_clang9_test
```
Download the `*.json.bz2` file(s) for that commit/job pair:
```
$ aws s3 cp s3://ossci-metrics/test_time/$CIRCLE_SHA1/$CIRCLE_JOB/ $DATA_DIR/ossci-metrics/test_time/$CIRCLE_SHA1/$CIRCLE_JOB --recursive
```
And feed everything into `test/print_test_stats.py`:
```
$ bzip2 -kdc $DATA_DIR/ossci-metrics/test_time/$CIRCLE_SHA1/$CIRCLE_JOB/*Z.json.bz2 | torch/testing/_internal/print_test_stats.py --compare-with-s3 --use-json=/dev/stdin $DATA_DIR/test/test_$ARBITRARY_TEST
```

Summary:
Closes https://github.com/pytorch/pytorch/issues/50513 by resolving all four checkboxes. If this PR is merged, I will also modify one or both of the following wiki pages to add instructions on how to use this `mypy` wrapper for VS Code editor integration:
- [Guide for adding type annotations to PyTorch](https://github.com/pytorch/pytorch/wiki/Guide-for-adding-type-annotations-to-PyTorch)
- [Lint as you type](https://github.com/pytorch/pytorch/wiki/Lint-as-you-type)
Pull Request resolved: https://github.com/pytorch/pytorch/pull/50826
Test Plan:
Unit tests for globbing function:
```
python test/test_testing.py TestMypyWrapper -v
```
Manual checks:
- Uninstall `mypy` and run `python test/test_type_hints.py` to verify that it still works when `mypy` is absent.
- Reinstall `mypy` and run `python test/test_type_hints.py` to verify that this didn't break the `TestTypeHints` suite.
- Run `python test/test_type_hints.py` again (should finish quickly) to verify that this didn't break `mypy` caching.
- Run `torch/testing/_internal/mypy_wrapper.py` on a few Python files in this repo to verify that it doesn't give any additional warnings when the `TestTypeHints` suite passes. Some examples (compare with the behavior of just running `mypy` on these files):
```sh
torch/testing/_internal/mypy_wrapper.py $PWD/README.md
torch/testing/_internal/mypy_wrapper.py $PWD/tools/fast_nvcc/fast_nvcc.py
torch/testing/_internal/mypy_wrapper.py $PWD/test/test_type_hints.py
torch/testing/_internal/mypy_wrapper.py $PWD/torch/random.py
torch/testing/_internal/mypy_wrapper.py $PWD/torch/testing/_internal/mypy_wrapper.py
```
- Remove type hints from `torch.testing._internal.mypy_wrapper` and verify that running `mypy_wrapper.py` on that file gives type errors.
- Remove the path to `mypy_wrapper.py` from the `files` setting in `mypy-strict.ini` and verify that running it again on itself no longer gives type errors.
- Add `test/test_type_hints.py` to the `files` setting in `mypy-strict.ini` and verify that running the `mypy` wrapper on it again now gives type errors.
- Change a return type in `torch/random.py` and verify that running the `mypy` wrapper on it again now gives type errors.
- Add the suggested JSON from the docstring of `torch.testing._internal.mypy_wrapper.main` to your `.vscode/settings.json` and verify that VS Code gives the same results (inline, while editing any Python file in the repo) as running the `mypy` wrapper on the command line, in all the above cases.

Summary:
This is follow up on https://github.com/pytorch/pytorch/issues/49799.
* uses `torch.cuda.synchronize()` to validate CUDA assert instead of inspecting error message.
* remove non CUDA tests.
hopefully can reproduce why slow_tests fails but not normal test. since the test still runs for >1min.
