RuntimeError: Error building extension 'wkv_cuda_v1' about chatrwkv HOT 2 CLOSED

So I realize I did not include enough of the trace to allow the community to easily see what is going on. The first exception in my trace is:

/usr/include/c++/11/bits/std_function.h:435:145: error: parameter packs not expanded with ‘...’

which makes me think I have an issue with nvcc and gcc not playing nice together. I've got nvcc 11.5 and gcc 11.4 installed, and I'm reading on the web that this issue is being thrown with certain gcc versions after 10. I will explore and update here.

from chatrwkv.

Ok, solution found. My nvcc and gcc were in conflict because my implementation was pulling from gcc-11 and ignoring my installation of gcc-10. I fixed this by removing gcc-11, installing gcc-10 and setting up alternatives appropriately:

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 10
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-10 10
sudo update-alternatives --config gcc
sudo update-alternatives --config g++
sudo update-alternatives --install /usr/bin/c++ c++ /usr/bin/g++-10 10
