Error when tried to import generate_forecasting_h5

[zyandtom]

from argoverse.evaluation.competition_util import generate_forecasting_h5
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/yang.zeng/argoverse-api/argoverse/evaluation/competition_util.py", line 13, in <module>
    import quaternion
ModuleNotFoundError: No module named 'quaternion'

when I have installed quaternion, another error emerged, about numpy crash:

from argoverse.evaluation.competition_util import generate_forecasting_h5
RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd
Traceback (most recent call last):

    from .numpy_quaternion import (
ImportError: numpy.core.multiarray failed to import

I know it is not compatible for numpy, so I installed numpy=1.19, but still the same error, why?

Hi @zyandtom, thanks for the heads up.

Looks like we forget to remove quaternion from this file. You won't need it for the forecasting file generation, so please comment out the import quaternion for now and pip uninstall quaternion, and I'll put up a PR ASAP to refactor this file and remove that dependency.

Thanks.
