Comment (by reneeotten):

 I suspect you've used {{{python_select}}} to have it start {{{python310}}}
 when typing {{{python}}} - correct? Also did you make sure to only install
 Python packages trough MacPorts, in other words no mixing of stuff with
 {{{pip}}} and such?

 I don't see how any of this can happen. I am pretty sure your problem is
 related to the fact that Python 3.10 imports packages that were installed
 for Python 3.9. Nothing in MacPorts will do that for you and it works fine
 for me, so I bet it is something specific to your system.... Inspect your
 environment variables for example and make sure you haven't set
 {{{PYTHONPATH}}} and such.
