CUDA error at /home/tom/NVIDIA_CUDA-10.1_Samples/common/inc/helper_cuda.h:744 code=35(cudaErrorInsufficientDriver) “cudaGetDeviceCount(&device_count)”
This error showed up spontaneously in my code which was running nicely yesterday. Even backed up versions of the code throw this same error now. I am not very skilled at this type of debugging.
I reinstalled the nvidia drivers to my Ubuntu system, but nothing changed.
