I always thought i have:

Cuda compilation tools, release 10.0, V10.0.130 as determined by:

nvcc --version

However

conda info list

prints:

   virtual packages : __cuda=10.2
                      __glibc=2.27

Next, i checked:

nvidia-smi

NVIDIA-SMI 440.100      
Driver Version: 440.100      
CUDA Version: 10.2

In case i have indeed: release 10.0, V10.0.130

How can i change the virtual environment for conda? Or do i have two versions installed (by mistake)?

(all on Ubuntu 18.04)

  • It is possible to have more than one CUDA version installed, and in factyou evidently have more than one version installed. anaconda installs a subset of the usual CUDA toolkit, in separate locations of its choosing. So you appear to have a conda-subset of 10.2. You also appear to have an ordinary CUDA install of 10.0. The version reported by `nvidia-smi` is not actually the installed CUDA toolkit version but the installed CUDA driver version (the GPU driver version is 440.100, the CUDA driver version is 10.2). – Robert Crovella Jul 21 '20 at 13:58
  • Thanks! How can i tell conda to use the ordinary CUDA 10.0 install. The 10.2 install was likely triggered as unwanted security update (and removing it might cause other trouble). – Tobias R Jul 22 '20 at 10:40
