Demo fails
I tried to run demo, but it failed with this error;
from .pykdtree.kdtree import KDTree
File "__init__.pxd", line 885, in init pykdtree.kdtree
ValueError: numpy.ufunc has the wrong size, try recompiling. Expected 192, got 216
Probably this is caused by numpy version (https://github.com/automl/auto-sklearn/issues/621). I will try to fix this.
Finally I solve the problem using docker environment. See https://github.com/autonomousvision/occupancy_flow/pull/9
Actually it worked on GTX1060, but it failed on GTX3070. But finally I fixed it and confirmed to finish demo even native (witout docker environment). I updated the pull request. So please check the above #9 pull request.
Thanks @MasahiroOgawa for creating the respective docker environment - I merged your pull request now!
