Cuda/ nvcc not found

If you used the Nano SD card image, then yes, it already has the CUDA Toolkit installed. Check under /usr/local/cuda to verify that it’s there.

Check that your ~/.bashrc file has these lines at the end, and if not, add them and restart your terminal:

$ export PATH=/usr/local/cuda/bin${PATH:+:${PATH}}
$ export LD_LIBRARY_PATH=/usr/local/cuda/lib64\
