Error: No module named 'datasets'

[Ishihara-Masabumi]

When I run the followint command line, the following error occurred.

$ python3 datasets/preprocess.py
Traceback (most recent call last):
  File "datasets/preprocess.py", line 4, in <module>
    from datasets.bvh_parser import BVH_file
ModuleNotFoundError: No module named 'datasets'

Please let me know how to fix it.

Maybe a little bit late, but add this at the beginning of datasets/preprocess.py

import sys
import os
project_root = os.path.abspath(os.path.join(os.path.dirname(file), '..'))
if project_root not in sys.path:
sys.path.insert(0, project_root)
