when I type on anaconda prompt:

nvidia-smi

it states that I have cuda version 11

but when I type 

conda list cudatoolkit

I get 10.1.243

  1. what is the difference between the commands?
  2. what is the difference between cuda and cudatoolkit?
  3. is the difference in versions a problem? if so, how to fix it?

    `nvidia-smi` tells you what version of CUDA the installed *driver* package supports, it doesn't tell you anything about what version of CUDA is installed. – njuffa Apr 15 '20 at 08:59
  • it answers 1/3 of my question. I still don't know what is the difference between cuda and cudatoolkit, and how to fix this mismatch of version. will downloading and installing cuda toolkit 10.1 fix the problem? – Moran Reznik Apr 15 '20 at 09:12
  • You don't need the versions to match. It is all explained [here](https://docs.nvidia.com/deploy/cuda-compatibility/index.html) (it's for Linux, but applies to Windows too). – Hristo Iliev Apr 15 '20 at 09:26
  • cudatoolkit is a misnamed conda package -- it contains the bare bones cuda runtime libraries required to support the CUDA accelerated python packages and nothing else. You need to separately install a supported driver and if you want anything else, like nvcc or other components from the NVIDIA cuda toolkit, you need to install that yourself. The "mismatch" is irrelevant -- as long as the version nvidia-smi shows is as large or greater than the runtime you are trying to use, everything will just work – talonmies Apr 15 '20 at 10:18
