Tensorrt: What is the meaning of Tactic when using trtexec
Hi, I'm trying to profile my model using trtexec.
I got this error but I can't understand the meaning of Tactic and message.
What is the meaning of Tactic?
Also, How can I calculate the time taken per layer?

Tactic is an opaque UID that TensorRT uses to identify its algorithm choice for a particular layer (or, if it fused some layers, a combination of layers.) Often these values are hashes of something-or-other, so don't expect to make anything useful of them.
For time per layer, your best option is to use either TensorRT's profiling interface, or NVIDIA's CUDA profiling tools.
