I'm having a similar issue on M1 chip of missing import but pip install requirements already satisfied

Similar issue, except I just get [1] 79802 illegal hardware instruction python upon running from pyllamacpp.model import Model

I was having the same issue because I had multiple versions of python. It might be worth a shot to just try changing your python version around some.

Any Lucky? days passed, and it seems the developer did not run a fix on this issue.

Sorry @laihenyi, I don't have a Mac so I couldn't debug the issue.
Could you please try to build from source in that case ? it is a straightforward process!

I encountered 2 problems:

1. My conda install was for the x86 platform, and I should have instead installed another binary for arm64
2. Installing from whl (pypi?) was pulling the x86 version, not the arm64 version of pyllamacpp

This ultimately was causing the binary to not be able to link with BLAS, as provided on macs via the accelerate framework (namely, could not find _clbas_sgemm, which is a function for single precision matrix multiplication). In simple terms, a dependency issue because of incompatible platforms.

I found that I had to fix both of the above issues - just fixing one did not work. Now, after a separate conda for arm64, and installing pyllamacpp from source, I am able to run the sample code.

Thanks so much @shivam-singhal for the solution. I really appreciate it.

Sorry,
I am not a code developer, however, I am an M1 MacBook user.
What could I do to help you to fix this bug?
remote-connect to my laptop to compile M1 binary?

This doesn't make sense, I'm not running this in conda, its native python3. What did you modify to correct the original issue, and why is everyone linking this to the pygpt4all import GPT4All when it seems to be a separate issue?
