CodePudding user response：

your python binary resides in /usr/local/bin and with your mount you override it with whatever is in /tmp path on your host

>docker run -it python:3.9.7-slim-bullseye /bin/bash
root@8c92c001fdaf:/# which python
/usr/local/bin/python

CodePudding user response：

It looks like the bind mount was the issue. I was mounting to /bin/usr, which was somehow causing the error.
