You may need to modify `chumpy` package to avoid errors. 
   
  * Comment line 11 in `${Your_Conda_Environment}/lib/python3.11/site-packages/chumpy/__init__.py`:
  ```
  from .ch import *
  from .logic import *

  from .optimization import minimize
  from . import extras
  from . import testing
  from .version import version as __version__

  from .version import version as __version__

  # from numpy import bool, int, float, complex, object, unicode, str, nan, inf
  ```
  * Add *"inspect.getargspec = inspect.getfullargspec"* in `${Your_Conda_Environment}/lib/python3.11/site-packages/chumpy/ch.py` (line 25). Now it should look like:
  ```
  #!/usr/bin/env python
  # encoding: utf-8
