Hi Michael,
The problem is that sudo doesn't preserve environment variables. The
easiest way to get around this is to pass -E to sudo:
iha...@obsidian:~
$ export CUDA_ROOT=/usr/local/cuda
iha...@obsidian:~
$ echo $CUDA_ROOT
/usr/local/cuda
iha...@obsidian:~
$ sudo sh -c 'echo $CUDA_ROOT'
iha...@obsidian:~
$ sudo -E sh -c 'echo $CUDA_ROOT'
/usr/local/cuda
Cheers,
Imran

Thanks, nvcc is actually on the path, which is why I found the message
confusing. I can type nvcc in bash and it runs and everything. I also
did "CUDA_ROOT='/usr/local/cuda'" in bash such that "echo $CUDA_ROOT"
prints "/usr/local/cuda". Also, usr/local/cuda definitely exists. So, it
would seem that I have taken care of both error conditions, and yet the
message persists.

Hi Michael,
The error message is sort of self-explanatory. You need to make 'nvcc'
(cuda compiler) available to installer. There are two ways to do it:
either add path to it (usually /usr/local/cuda/bin) to your $PATH
variable (by modifying bash profile, for example), or pass the path to
CUDA (usually /usr/local/cuda) as --cuda-path to configure.py of
PyCuda.
Best regards,
Bogdan
