Error during installation

[Possums]

I'm encountering the following error both when installing with pip and compiling from source.

Any ideas on how to resolve this?

It looks like the linker is failing to find the torch libraries. Could you also share:

• PyTorch Version (e.g., 1.0):
• OS (e.g., Linux):
• How you installed PyTorch (conda, pip, source):
• Build command you used (if compiling from source):
• Python version:

• Pytorch Version: 1.10.1+cpu
• OS: Clear Linux Server
• Pytorch Installation: pip
• Build command: python3 setup.py install
• Python version: 3.9.6

Thanks for the help!

Any chance you've figured this out? I haven't been able to reproduce on my end.
