We are getting an error when serializing a TensorRT engine using RTX 4070:
caskUtils.cpp::trtSmToCask: Error Code 1: Internal Error (Unsupported SM: 0x809)
The documentation for 8.0.1 say the card supports >SM5.0, and the card is SM8.9. But this post implies cards also have minimum supported TensorRT/CUDA versions.
What are the supported versions for the RTX 4070, and where can I find this information in the future?
TensorRT Version: 8.0.1
GPU Type: RTX 4070
Nvidia Driver Version: 525
CUDA Version: 11.4.2
CUDNN Version: 8
Operating System + Version: ubuntu20.04
We recommend that you try TensorRT version 8.5 or above. Before version 8.5, SM 8.9 was not supported.
Please refer to the release notes for details.
Thanks for your quick response!
I’ve read the release notes, but I cannot see anywhere that explains forward compatibility of TRT with the latest GPUs.
For example, will TRT8.5 be supported on the next gen 50-series cards? Does a new SM version always require a new release of TRT?
This is important to us as this affects the compatibility of our product releases.
