@jeremy In your notebook output, resnet34 learn.fit_one_cycle(4) took around 2 minutes in the main video notebook (using sagemaker)
While I can see, it took for you around 1 minute in the github lesson 1 notebook.
Can you please mention what was the specs for the video lesson nb training and what was for the github nb?
This could be useful for all of us as a baseline to check whether our local setup is working well.
For me I am getting much lower speed (12 min) for gtx1080ti with an old cpu (Xeon® W3503) which is running 100%, and from time to time the gpu utilization pops up from 2% to 70-90%
The 1st thing I should do is to get rid of the gpu risers that is lowering the pcie2 x16 into pcie2 x1 which is the only way to install multiple gpu for me.
