when I install pycuda by this instruction:

pip install pycuda

but there is an error:

src/cpp/cuda.hpp:14:10: fatal error: cuda.h: No such file or directory

but I have installed the cuda toolkit.this is the result of nvcc -V

[root@localhost include]# nvcc -V

In my case I met both issues:

-lcurand not found

and 

src/cpp/cuda.hpp:14:10: fatal error: cuda.h: No such file or directory

And exporting C_INCLUDE_PATH didn't helped me. Instead I needed to export general version of C_INCLUDE_PATH -- CPATH:

export CPATH=$CPATH:/usr/local/cuda/include
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/cuda/lib64

This is how I solved the problem on Jetson NANO:

sudo pip3 install --global-option=build_ext --global-option="-I/usr/local/cuda-10.0/targets/aarch64-linux/include/" --global-option="-L/usr/local/cuda-10.0/targets/aarch64-linux/lib/" pycuda

You probably need to specify path to CUDA:

export C_INCLUDE_PATH=${CUDA_HOME}/include:${C_INCLUDE_PATH}
export LIBRARY_PATH=${CUDA_HOME}/lib64:$LIBRARY_PATH

Please make sure that echo ${CUDA_HOME} does provide some sensible output.

Find out where Cuda is installed on the system using find / - type d - name cuda 2>/dev/null

Use or which every location cuda is found on

export PATH=/usr/local/cuda-VERSION/bin:$PATH

Then

pip install pycuda

Here is another solution that worked for me. This solution was taken from here.

$ export PATH=/usr/local/cuda/bin:$PATH
$ sudo apt-get install python-dev
$ pip install numpy
$ export CUDA_ROOT=/usr/local/cuda
$ pip install pycuda
