Install error on Ubuntu 14.04, CUDA 6.5 with setup.py/pip

nvcc -I/usr/include/python2.7 -c cudamat/cudamat.cu -o build/temp.linux-x86_64-2.7/cudamat/cudamat.o -O --ptxas-options=-v --compiler-options '-fPIC' unable to execute nvcc: No such file or directory error: command 'nvcc' failed with exit status 1

There is little chance that this comes from my configuration, since I reverted to a346369447e9b2dbb730e4218a4c0eaa153840ef and ran make and the tests successfully.

Clearly nvcc compiler is not the path, then I tried PATH = PATH + “:/usr/local/cuda-7.5/bin”, it still doesn’t work

This doesn’t change where nvcc is searched for, that PATH is just a backup of the environment variable to avoid Anaconda sneaking in a wrong MSVC version on Windows. You’d need to modify os.environ['PATH'], or just change your PATH environment variable. Did you restart your terminal after changing the .bashrc? You can try echo $PATH to see if the path is correct.

Note that when you’re using sudo, the PATH will be overridden, no matter what you set it to. You can do sudo PATH="$PATH" ... to have the environment carry over.

@nateGeorge: What about pip install http://github.com/f0k/cudamat/archive/simplify-compile.zip, does this fail as well? It’s a little different, but not sure if this would help. Did you try installing with sudo or without?
