python -m torch_ort.configure fail

[kimkeithvn]

it seems the length of filename result in this error. Here is the log.
Any idea about solving the problem? thx

running build
running build_ext
building 'aten_op_executor' extension

Not sure why the path is so long, the error reported is "ninja: error: Stat(D:/python/Anaconda/envs/dl/lib/site-packages/onnxruntime/training/ortmodule/torch_cpp_extensions/build/temp.win-amd64-cpython-310/Release/python/Anaconda/envs/dl/lib/site-packages/onnxruntime/training/ortmodule/torch_cpp_extensions/cpu/aten_op_executor/aten_op_executor.obj): Filename longer than 260 characters" Is that possible to shorten the python installation path?

You can bypass this error by enabling long path name:
Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem' -Name LongPathsEnabled -Type DWord -Value 1

However, you'll still bump into other issues since ORTModule does not support Windows for now.
