I’m getting the following warnings when building an engine:
WARNING: Skipping tactic 0 due to kernel generation error.
As well as:
WARNING: Convolution + generic activation fusion is disable due to incompatible driver or nvrtc
I’m running on:
CUDA driver: 495.29.05
What is the problem? They look serious enough so I don’t think I should simply ignore them.
I do not have such a problem on CUDA 11.4 + TensorRT 8.2.2. However I cannot use TRT 8.2.2 due to a performance regression, so I’m stuck in TRT 8.0.3, which according to the documentation only supports up to CUDA 11.3, not CUDA 11.4.
Thanks for the reply. The model is proprietary so I cannot share it here, I will try to prepare a smaller sample.
Until then, can you give a hint as to what is happening? In general, error messages should be self-contained, descriptive and actionable for the users. The error messages above don’t tell me what the problem is.
We are unable to reproduce this issue on latest TRT version.
Above error says same thing issue due to NVRTC or CUDA related error.
As mentioned in the release notes of 8.0.3 version, we fixed a known CUDA 11.4 NVRTC issue during kernel generation.
We recommend you to please upgrade CUDA version and try. Also we suggest to use latest TensorRT if possible.
