Wrong libprotobuf Version Dependency?

[astrostu]

I'm doing a new install and was running into issues for any of the available PLIO versions (1.5.2–1.5.5). I install it, then open Python and do something simple like import plio and the following results:

  File "<stdin>", line 1, in <module>
  File "/opt/anaconda3/envs/plio/lib/python3.12/site-packages/plio/__init__.py", line 17, in <module>
    from . import io
  File "/opt/anaconda3/envs/plio/lib/python3.12/site-packages/plio/io/__init__.py", line 22, in <module>
    from . import io_controlnetwork
  File "/opt/anaconda3/envs/plio/lib/python3.12/site-packages/plio/io/io_controlnetwork.py", line 10, in <module>
    from plio.io import ControlNetFileV0002_pb2 as cnf
  File "/opt/anaconda3/envs/plio/lib/python3.12/site-packages/plio/io/ControlNetFileV0002_pb2.py", line 34, in <module>
    _descriptor.EnumValueDescriptor(
  File "/opt/anaconda3/envs/plio/lib/python3.12/site-packages/google/protobuf/descriptor.py", line 920, in __new__
    _message.Message._CheckCalledFromGeneratedFile()
TypeError: Descriptors cannot be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

I exited Python, ran conda install protobuf=3.20, and now it seems to be working -- or, at least, doesn't throw errors when I just run import plio. The version that was installed originally was 5.27.5. I haven't tested the rest of my code so I'm not sure if this relatively simple work-around solved things, but it's something to look into. Note that this is on an M1-chip Mac -- I've been migrating to arm-64 architecture for all my conda installs except ISIS to try to avoid the Rosetta 2 translation hit.
