@lincolnBush What platform are you running this notebook and get this error? I didn't get this issue on Ubuntu 14.04 or 16.04.

For the third issue, the reason is "./data/caltech_train.rec" has changed to "./data/caltech.rec"

ImportError Traceback (most recent call last) in () 3 import os 4 import numpy as np ----> 5 from tensorboard import summary 6 from tensorboard import FileWriter 7 ImportError: No...

OK. Thank you!

Yes. We will first finalize keras/mxnet for 1.2.2 and then switch to 2.0.

Can you provide full codes for your experiment? Sometimes multi-cpu won't get any boost or can even slow down training since overhead of hardware communication.

@Wendison You can benchmark pure training time without data IO to see if data IO is the bottleneck.

In which notebook?

@Gyaya Usually this issue comes from training. Can you post your training code? After you do backward for a network, you want to make sure all the gradients computed by...
