How to delete corrupted trace?

Hi Jesse, thanks for your suggestions. I tried both of them, but still to no avail. Here I attached the pycache directory that I removed. This directory is inside my working directory. I also try to run my script in other directory (under the same conda environment) but the problem still persists. When I change environment (or create a new one containing pymc) the problem was solved when I run my script using that (new) environment. Any ideas?
