I have multiple versions of cuda toolkit and driver on my server ( 8.0, 9.2, and 10.0 ).
My g++ and gcc version is: 7.3.1
when I run python build.py install, it throws an error:

error: command '/usr/local/cuda/bin/nvcc' failed with exit status 1
This line /usr/local/cuda/bin/nvcc in the message above is strange because
I have set the environmnent variable to go into '/usr/local/cuda10.0` first.
$ echo $PATH
/home/msl/.virtualenvs/venv_wavenet/bin:/usr/local/cuda-10.0/bin:/home/msl/maum/bin:/home/msl/.virtualenvs/venv_wavenet/bin:/opt/rh/devtoolset-7/root/usr/bin:/usr/local/cuda-10.0/bin
and when I run nvcc --version, I get this:
$ nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver

Cuda compilation tools, release 10.0, V10.0.130
which is what I would expect, since I have cuda 10.0 in my PATH first. So why is cpp_extension going to /usr/local/cuda/bin/nvcc?
