3eeb4347 - Make permission errors more human readable (#66492)

Make permission errors more human readable (#66492) Summary: `_mkdir_p` feels like a remnant of Python-2 era, add `exist_ok` argument and re-raise OSError to make it more human readable. After the change attempt to build PyTorch in a folder that does not have write permissions will result in: ``` % python3.6 setup.py develop Building wheel torch-1.10.0a0+git9509e8a -- Building version 1.10.0a0+git9509e8a Traceback (most recent call last): File "/Users/nshulga/git/pytorch-worktree/tools/setup_helpers/cmake.py", line 21, in _mkdir_p os.makedirs(d, exist_ok=True) File "/opt/homebrew/Cellar/python36/3.6.2+_254.20170915/Frameworks/Python.framework/Versions/3.6/lib/python3.6/os.py", line 220, in makedirs mkdir(name, mode) PermissionError: [Errno 13] Permission denied: 'build' The above exception was the direct cause of the following exception: Traceback (most recent call last): File "setup.py", line 895, in <module> build_deps() File "setup.py", line 370, in build_deps cmake=cmake) File "/Users/nshulga/git/pytorch-worktree/tools/build_pytorch_libs.py", line 63, in build_caffe2 rerun_cmake) File "/Users/nshulga/git/pytorch-worktree/tools/setup_helpers/cmake.py", line 225, in generate _mkdir_p(self.build_dir) File "/Users/nshulga/git/pytorch-worktree/tools/setup_helpers/cmake.py", line 23, in _mkdir_p raise RuntimeError(f"Failed to create folder {os.path.abspath(d)}: {e.strerror}") from e RuntimeError: Failed to create folder /Users/nshulga/git/pytorch-worktree/build: Permission denied ``` Fixes https://github.com/pytorch/pytorch/issues/65920 Pull Request resolved: https://github.com/pytorch/pytorch/pull/66492 Reviewed By: seemethere Differential Revision: D31578820 Pulled By: malfet fbshipit-source-id: afe8240983100ac0a26cc540376b9dd71b1b53af
