CreateML is pretty slow on Nvidia 750m

Hello.


Im training a model with 70,000 images on my macbook pro (mid 2014) with 750m GPU and its pretty slow, (aprox 6 hours). I could test the training model with the 2014 model from my friend with Iris Pro graphics, and mine is 2x slower.


Do you know i can do something for accelerating this? I couldnt believe Iris pro is 2x more powerfull computing a training model than 750m. Its possible to force CreateML to use Iris Pro instead discrete graphics?


Thanks.
