Please correct me if I am wrong.įirst, let me recap the situation with a conda-installed CuPy: My conclusion is that the present issue is not solvable. I thought about it very carefully, and also inspected how Numba picks up the CUDA libs.
I have installed cuda 10.2 on my system and it seems that there isn't uninstall_cuda_x.x.pl file, but nvidia replaced this file by cuda-uninstaller file in the same directory.NVM, Ignore my $CONDA_PREFIX question above. Note that the above method works if you set $PATH variable correctly, So if your nvcc command not works then please use the below command in terminal to find cuda version ls /usr/local/ | grep cuda The result will look like this: nvcc: NVIDIA (R) Cuda compiler driverĬopyright (c) 2005-2017 NVIDIA CorporationĬuda compilation tools, release 9.0, V9.0.176 NOTE: How do you figure out which cuda has been installed on your Ubuntu system?īy using the command nvcc, you can see that my cuda version is 9.0 in the last line of the nvcc result. There is a file named uninstall_cuda_9.0.pl in this directory (please note that the cuda version is 9.0, so run the uninstall_cuda_9.0.pl to remove cuda completely from your system! chmod +x uninstall_cuda_9.0.plĪs soon as you enter your password, the cuda files will be erased. You need to change your directory to the cuda's path, which is by default /usr/local/cuda-x.y/bin where x.y is your cuda version, you can do this by using the below command: (I have cuda 9.0= x.y) cd /usr/local/cuda-9.0/bin Which packages should I remove and which should not be removed to get this done?įor removing cuda, Nvidia has prepared a file (I presume this is a standard method). Packages, like bumblebee, I want to remain as they are.
