I've just spent the morning uninstalling and reinstalling different versions of Nvidia driver (Linux) to get nvcc back for llama.cpp after Linux Mint did an update - I had CUDA 12.3 and 12.4 (5GB each), in conflict, with no guidance. 550 was the charm, not 535 that was fine in January. This is the third time I'm going this since December. It is painful. I'm not in a hurry to return to my cuDF experiments as I'm pretty sure that'll be broken too (as it has been in the past). I'm the co author of O'Reilly's High Performance Python book and this experience mirrors what I was having with pyCUDA a decade back.
