COMPILED_WITH_CUDA error requires libcuda.so

[nickums]

"CUDA Setup failed despite GPU being available. ... the main CUDA library was not detected....
Find the cuda library via: find / -name libcuda.so 2>/dev/null
2b): Once the library is found add it to the LD_LIBRARY_PATH: "

I have CUDA installed with pytorch. I do not have the file libcuda.so anywhere in my site-packages.
what can I do?
