Historically, TensorRT has only supported NCHW I/O data and models/engines.
However now I see here that a NHWC input is being used.
There’s no documentation about this in the TensorRT Developer Guide.
So: can you clarify:
- Is NHWC is supported?
- Is it only for I/O or also internally inside the model?
- What are the implications of using NHWC over NCHW? (e.g. will it be slower?)
- What format conversions does TRT internally?
