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

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.
