no mayavi in this image?

Hi, Thank you for your work! I have a question. After I pulled the image from docker hub, I mount the kitti data in the container(/tmp/OpenPCDet/data/kitti/); And I also mount the weights file in the container too. I try to run the demo.py. I got this error: No module named 'mayavi'.

Is this normal? thank you a lot!
