3. Exported .bvh from blender
4. Tried to run this: (script.py)

import json import os from os import listdir from os.path import isfile, join from bvhtomimic import BvhConverter

converter = BvhConverter("./Settings/settings.json") converter.convertBvhFile("/home/rkj/Work/BvhToDeepMimic/input/OG_Rig.bvh", loop=False)

5. Produced Error:
