cudnn 8 support: panic: Expected symbol in library: DlSym { desc: "/lib/x86_64-linux-gnu/libcudnn.so.8: undefined symbol: cudnnAdvVersionCheck" } #433

Description

@nemosupremo

When cudarc (with cudnn) is a built for cuda 11.8 and dynamic-loading, the library will panic on undefined symbol.

Even though version_check is only tested on CUDA 12, the dynamic loading on CUDA 11 still tries to load cudnnAdvVersionCheck where it doesn't exist.
