Convert type comments to annotations in torch/nn (#72662)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/72662
This commit was produced by running
```
python -m libcst.tool codemod --no-format --jobs=1 convert_type_comments.ConvertTypeComments caffe2/torch/nn/ --no-quote-annotations
```
and then manually fixing unreadable lines by breaking up very
long function defintiion (unfortuantely
it's very difficult to fully automate tranforms of code that
isn't autoformatted).
Test Plan:
Wait for CI. This should be safe, the types all appear to be valid - but it's
always good to let the jit tests run, in some cases we find typing errors that
crash tests.
