Support correct TRT/anything inference

[Sem4ik228]

HI! Thanks for this repo.
It seems like needs to add conversation between pytorch and onnx to make inference. I mean, now this repo does not have the functionality for inference, which is strange for the creators of the network that posits itself like best real-time action detection NN. Pls add support for onnx and minimal C++ example on TRT and OpenVINO. Now i don't understand, what I need to do with 5D input tensor in TRT.
Thanks!
