Summary: *Context:* https://github.com/pytorch/pytorch/issues/53406 added a lint for trailing whitespace at the ends of lines. However, in order to pass FB-internal lints, that PR also had to normalize the trailing newlines in four of the files it touched. This PR adds an OSS lint to normalize trailing newlines. The changes to the following files (made in 54847d0adb9be71be4979cead3d9d4c02160e4cd) are the only manually-written parts of this PR: - `.github/workflows/lint.yml` - `mypy-strict.ini` - `tools/README.md` - `tools/test/test_trailing_newlines.py` - `tools/trailing_newlines.py` I would have liked to make this just a shell one-liner like the other three similar lints, but nothing I could find quite fit the bill. Specifically, all the answers I tried from the following Stack Overflow questions were far too slow (at least a minute and a half to run on this entire repository): - [How to detect file ends in newline?](https://stackoverflow.com/q/38746) - [How do I find files that do not end with a newline/linefeed?](https://stackoverflow.com/q/4631068) - [How to list all files in the Git index without newline at end of file](https://stackoverflow.com/q/27624800) - [Linux - check if there is an empty line at the end of a file [duplicate]](https://stackoverflow.com/q/34943632) - [git ensure newline at end of each file](https://stackoverflow.com/q/57770972) To avoid giving false positives during the few days after this PR is merged, we should probably only merge it after https://github.com/pytorch/pytorch/issues/54967. Pull Request resolved: https://github.com/pytorch/pytorch/pull/54737 Test Plan: Running the shell script from the "Ensure correct trailing newlines" step in the `quick-checks` job of `.github/workflows/lint.yml` should print no output and exit in a fraction of a second with a status of 0. That was not the case prior to this PR, as shown by this failing GHA workflow run on an earlier draft of this PR: - https://github.com/pytorch/pytorch/runs/2197446987?check_suite_focus=true In contrast, this run (after correcting the trailing newlines in this PR) succeeded: - https://github.com/pytorch/pytorch/pull/54737/checks?check_run_id=2197553241 To unit-test `tools/trailing_newlines.py` itself (this is run as part of our "Test tools" GitHub Actions workflow): ``` python tools/test/test_trailing_newlines.py ``` Reviewed By: malfet Differential Revision: D27409736 Pulled By: samestep fbshipit-source-id: 46f565227046b39f68349bbd5633105b2d2e9b19

Benchmarks for TorchScript models
|
|
|
|
For most stable results, do the following:
|
|
- Set CPU Governor to performance mode (as opposed to energy save)
|
|
- Turn off turbo for all CPUs (assuming Intel CPUs)
|
|
- Shield cpus via `cset shield` when running benchmarks.
|
|
|
|
Some of these scripts accept command line args but most of them do not because
|
|
I was lazy. They will probably be added sometime in the future, but the default
|
|
sizes are pretty reasonable.
|
|
|
|
## Test fastrnns (fwd + bwd) correctness
|
|
|
|
Test the fastrnns benchmarking scripts with the following:
|
|
`python -m fastrnns.test`
|
|
or run the test independently:
|
|
`python -m fastrnns.test --rnns jit`
|
|
|
|
## Run benchmarks
|
|
|
|
`python -m fastrnns.bench`
|
|
|
|
should give a good comparison, or you can specify the type of model to run
|
|
|
|
`python -m fastrnns.bench --rnns cudnn aten jit --group rnns`
|
|
|
|
## Run model profiling, calls nvprof
|
|
|
|
`python -m fastrnns.profile`
|
|
|
|
should generate nvprof file for all models somewhere.
|
|
you can also specify the models to generate nvprof files separately:
|
|
|
|
`python -m fastrnns.profile --rnns aten jit`
|
|
|
|
### Caveats
|
|
|
|
Use Linux for the most accurate timing. A lot of these tests only run
|
|
on CUDA.
