You actually don't even need the iGPU for simple MNIST training. The CPU is enough. Check out the sample MNIST training example with Tensorflow. If you are asking about using the iGPU for a bit more power, most frameworks don't support them. The only frameworks with which you can use with iGPUs are which have OpenCL support, like caffe[1] (even for those you need to have a recent enough CPU) Tensorflow either uses CPU or CUDA (Not even AMD, but the support is coming for openCL) [1]:https://github.com/BVLC/caffe/tree/opencl https://github.com/BVLC/caffe/tree/opencl
