GT 750M, trying to install Tensorflow

My laptop already has GeForce GT 750M GPU in it.

And my CUDA version is 8.0.

I am trying to use TensorFlow in my Ubuntu 16.04.

Is CUDA that is already in my laptop different from CUDA toolkit?

Do I still need to install CUDA toolkit ?

The CUDA you are referring to IS the CUDA Toolkit

I have Tensorflow (master - first days of May 2016) running on my ARCH Linux laptop with 2xSLI nVidia 750M with Cuda Toolkit 8 and CuDNN 4, and it works perfectly, compiled with gcc 5.3 (modified cuda headers to make it compile…)
