Thanks for this PR @terjekv !

We discussed this at a support meeting and suggest the following:

  • print the unaltered error message (e.g., just cat $nvidia_smi_out)
  • print a hint how this could be fixed (you mentioned that you fixed this)

Does this sound ok?

rm -f $nvidia_smi_out
exit 4
fi

nvidia_smi_info=$(head -1 $nvidia_smi_out)
cuda_cc=$(echo $nvidia_smi_info | sed 's/, /,/g' | cut -f4 -d, | sed 's/\.//g')
log "DEBUG" "accelpath: CUDA compute capability '${cuda_cc}' derived from nvidia-smi output '${nvidia_smi_info}'"
