I have a very temporary solution until a real fix is available. This is for those who are very hesitant to disable inspections, but who can’t stand the warnings being listed in PyCharm.
In one of your files in PyCharm, type in torch.abs(). Right click on abs, and select Go To -> Declaration. This will drop you into PyCharm’s auto generated python stubs for PyTorch. For any of the functions that are giving you a warning, just copy an existing function stub, and give it the proper signature for the missing function (don’t worry about the example or description). Your manually added pieces will certainly be overwritten when you make a change to the interpreter that results in re-caching, but it’ll allow you to get rid of the warnings for now at least (and fix some autocomplete, etc).
