Good morning,

I am currently trying to create a python script that hides atoms and shows ribbons in a .pdb file.

However, I am getting an error while trying to initialize a session. I've been trying to debug the problem to the best of my ability, but I am unable to figure out the issue.

My code:
```
import chimerax.core.session as cxsession
session = cxsession.Session('name')
```

My error:
```
 File "./test.py", line 15, in <module>
    session = cxsession.Session('name')
  File "/opt/UCSF/ChimeraX/lib/python3.7/site-packages/chimerax/core/session.py", line 437, in __init__
    self.app_name = app_name
  File "/opt/UCSF/ChimeraX/lib/python3.7/site-packages/chimerax/core/session.py", line 508, in __setattr__
    if not name.startswith('_') and self.snapshot_methods(value, base_type=StateManager) is not None:
  File "/opt/UCSF/ChimeraX/lib/python3.7/site-packages/chimerax/core/session.py", line 535, in snapshot_methods
    from .serialize import PRIMITIVE_TYPES
  File "/opt/UCSF/ChimeraX/lib/python3.7/site-packages/chimerax/core/serialize.py", line 42, in <module>
    from ._serialize import msgpack_serialize_stream, msgpack_deserialize_stream, PRIMITIVE_TYPES
ImportError: libpython3.7m.so.1.0: cannot open shared object file: No such file or directory
```

I look forward to your assistance.

Best,
Alexander
