Dockerfile half updated?

[GimpyWilliams]

The dockerfile seems to be installing a mix of dependencies between Open MMLabs, Nvidia, PyTorch, and TensorRT. I'm struggling to reconcile them.

I try mmcv==1.5.0 but it forces mmcv-full==1.7.0 which fails on the unit testing. And finding the right CUDA version that also connects properly with TensorRT is a struggle, as there's a lot of overlap.

Is there a way to reconcile these?
