Problems using GPU on Macbook Pro ... any ideas?

I have a 2015 macbookpro (OS X Yosemite) with a NVIDIA GeForce GT 750M card.

Installed the latest version of CUDA (8.0) and followed the directions from here:

Getting this error when attempting to use the GPU:

WARNING (theano.sandbox.cuda): CUDA is installed, but device gpu is not available (error: Unable to get the number of gpus available: CUDA driver version is insufficient for CUDA runtime version)


Problem: Installed the latest version of CUDA (8.0) when my driver required 7.5

Solution: Uninstalled 8.0 and then installed 7.5 (see #3 and #4 below), downloaded the proper version of cuDNN and copied the relevant files into the appropriate directories (under /usr/local/cuda), made sure my paths were set correctly in ~/.bash_profile … and voila.

Links to help others looking to develop locally on their OS X machines that aided me:


@wgpubs how does the macbook gpu perform?

@stickperson Not very well at all.

In fact, it was so poor that I pretty much switched to running everything on my Windows laptop.

Outside of some of the smaller notebooks in the course, I’d advise using the EC2 server or considering Windows.

Here’s my setup

I have checked your post. Did you install it on virtual machine? since the bash file is for Linux I think.

Sorry, just saw this. This writeup was for setting up on my MBP. No VMs just bare metal.

Just a heads up - I recently got a new Macbook Pro Retina with the i7 (Gen 8).

I migrated my old profile from my 2017 Retina and has the same issues.

To fix, I removed these CUDA files manually:
