R(2+1)D unit #322

Conversation

Summary:

  • Implement R(2+1)D unit (https://arxiv.org/abs/1711.11248).
  • Compared with vanilla R3D model, in R(2+1)D we replace a 3D conv with a 2D spatial conv and a 1D temporal conv, while the total No. of model parameters are kept the same.
  • We use R(2+1)D unit in ResNeXt3DStem and BasicTransformation.

@vreis For the cpu_tests, how does the resnext3d.py fail the isort test?
