Fallback MMTF loader support broken #225

Closed speleo3 closed 2 years ago

speleo3 commented 2 years ago

If PyMOL is compiled with --use-msgpackc=no then it would fall back to chempy.mmtf to load MMTF files. This fallback is broken with msgpack-python 1.0 which changed the default of raw=True to raw=False.

Steps to reproduce:

  1. Compile PyMOL with --use-msgpackc=no
  2. fetch 1ubq, type=mmtf

Result: Nothing gets loaded (and no error message)
