Description
when i try to train using 6 channel i get this error : RuntimeError: Given groups=1, weight of size 32 6 3 3, expected input[8, 3, 336, 336] to have 6 channels, but got 3 channels instead
code is exactly same as this : https://github.com/lyft/nuscenes-devkit/blob/master/notebooks/Reference%20Model.ipynb

Research direction
Start with the Reference Model notebook linked in the issue and reproduce the training run that reports the channel mismatch. Trace the input preparation and model entry point to determine why the batch has three channels instead of six; done means six-channel training reaches the next stage without this RuntimeError.
