Why don't use dataparallel on i3d?

Here you disable dataparallel on i3d and I wonder the reason. Because of it using multi GPUs to train i3d becomes impossible.

I also tried to modify the code and implement multi GPUs, but I encountered "Runtime Error: Expected tensor for argument 1 'input' to have the same device as tensor for argument 2 'weight'; but device 1 does not equal 0"
