In R2021a, GPU Coder supports cuDNN 8.1.0. For more information, see Installing Prerequisite Products (GPU Coder). It is recommended to use this version of cuDNN as other versions have significant performance and accuracy issues with INT8 workflows.
When using GPU Coder with cuDNN 8.0.x to generate CUDA code for a quantized deep learning network in INT8 precision, you may experience different issues depending on the version of cuDNN 8.0 used. The table below summarizes the issues you may experience.
