Question on Modal-mask training

[yyunyu]

Hi, @junjie18
in ModalMask3D function I change the

CMT/projects/mmdet3d_plugin/datasets/pipelines/transform_3d.py

Line 850 in d3b1d78

elif seed > 0.5:

seed so that the camera + LIDAR training is done without LIDAR input and it shows that it doesn't work, can you explain why we have to have LIDAR data when we train the fusion model? (i.e. why it works when we test the model without lidar point, but in training it doesn't work) Thx.

Hi, have you try to compare camera+LiDAR training and only LiDAR training. I found that image branch does not work at all.
