Are you sure you installed it into the virtual environment? You need to activate that first. This is not an AutoGPTQ issue.

Oh thanks for the speedy response. Let me fix that and close this thread.

I am facing the same error. I am wondering if you had solved this?

Activate virtual environment and follow quick installation in the readme.

No need to build from git. Just
pip install auto-gptq

Or 11.8 cuda equivalent if you are still using that.

Thank you! Not sure why, but installing the latest version will not have this problem. This happens for 0.5.1

There have been some fixes but also you skip the build step if you install a released version from PyPi. This error occured, I think, because one of the build steps was trying to call python but it's sometimes python3 and python should be 2.7 but is not installed nor would it work. If you are in the proper virtual environment however, it will work and be the correct python version.
