Answer 1

Solved the problem

• List lib files on /usr/local/cuda-11.2/extras/CUPTI/lib64/lib*

  $ ls /usr/local/cuda-11.2/extras/CUPTI/lib64/lib*
  

• I could not find libcupti.so.11.0. Other files should be there such that libcupti.so, libcupti.so.11.2, ...

• Manage a link between libcupti.so.11.2 and libcupti.so.11.0 using a comand 'sudo ln -s'

  $ sudo ln -s /usr/local/cuda-11.2/extras/CUPTI/lib64/libcupti.so.11.2 /usr/local/cuda-11.2/extras/CUPTI/lib64/libcupti.so.11.0
  

• List lib files on /usr/lib/x86_64-linux-gnu/libcup*

  ls /usr/lib/x86_64-linux-gnu/libcup*
  

• I could not find libcupti.so.11.0. Other files should be there such that libcupti.so, libcupti.so,2, libcupti.so.10.1, ...

• Manage a link between libcupti.so.11.2 and libcupti.so.11.0 using a comand sudo ln -s

  $ sudo ln -s /usr/local/cuda-11.2/extras/CUPTI/lib64/libcupti.so.11.2 /usr/lib/x86_64-linux-gnu/libcupti.so.11.0
  

This fixed the problem for me
