OSError: File must be a valid c3d file: iostream error

[rmndrs89]

Loading the .c3d file is still problematic for me. I am not sure why. Checking the data path with either os.path.isfile(...) or via Path(..).exists() returns True. Is this a known issue?

>>> from pyomeca import Markers
>>> data_path = "datasets/pyomeca/tests/data/markers_analogs.c3d"
>>> import os
>>> os.path.isfile(data_path)
True
>>> from pathlib import Path
>>> Path(data_path).exists()
True
>>> markers = Markers.from_c3d(data_path, prefix_delimiter=":")
