cuda nvidia problem. modprobe: FATAL: Module nvidia not found.

I am trying to install caffe with gpu supported nvidia driver. I have nvidia GTX860M graphic card (msi GE702Pe Apache Pro computer with ubuntu Linux version 4.4.0-38-generic (kernel), (gcc version 4.8.4). When i try ‘make runtest’, i got the following error (I did Compilation with Make, yet i also got error with cmake one). On my software&Updates, it is written as: NVIDIA Corporation:Unknown (This device is using the recommended driver. It uses NVIDIA binary driver-version 352.63 from nvidia-352(proprietary, supported). I installed cuda as follows:

wget http://developer.download.nvidia.com/compute/cuda/7.5/Prod/local_installers/cuda-repo-ubuntu1404-7-5-local_7.5-18_amd64.deb

    sudo dpkg -i cuda-repo-ubuntu1404-7-5-local_7.5-18_amd64.deb

    sudo apt-get update

    sudo apt-get install cuda

For opencv installation, I used the command: conda install opencv.

I would appreciate your help regarding to the solution of the following error. Thank you in advance.
