title: Why does nvidia-smi show a wrong CUDA version?
body: <p>I have already read this previous issue, but it did not answer my question. <a href="https://stackoverflow.com/questions/53422407/different-cuda-versions-shown-by-nvcc-and-nvidia-smi">Different CUDA versions shown by nvcc and NVIDIA-smi</a></p>
  <p>The above issue answers the question whether there is a problem with the installation. But it does not answer my question &quot;If I install other applications in Python that require CUDA, which CUDA version should I assume that I have?&quot;.</p>
  <p>In the previous issue, the author had intentionally installed two different versions of CUDA on his system. But I have only installed CUDA 10.1 on my computer, yet Python claims that I have installed version 11.1.</p>
  <p>CUDA was installed on my computer following instructions on Nvidias homepage, by downloading installer files. I have not installed CUDA packages via pip or pip3 in python.</p>
  <p><strong>Version according to cmd.</strong>

  <p>If I install other applications in Python, which CUDA version should I assume that I have? How can I get rid of the 11.1 version, and only keep the 10.1 version?</p>
