Hello! I have set the num_inter_threads and num_intra_threads，but I haven't seen a big improvement in training time.A node has 24 CPUs, but only one CPU is used.I hope you can help me.

Which parameter do you set? num_inter_threads*num_intra_threads=num_total_threads

TensorFlow has explained it in the comment:

I have tried many kinds of inter and intra parameters,sush as 0 and 0 or 1 and 2 or 2 and 1......but it still used one CPU.My management system is PBS,can you provide a script for submitting task?Thank you very much!

I have solved this problem.Thanks a lot,and I want to know if the test datas also can be parallel calculated?

Do you mind if I ask how did you solve the problem? Is there any specific set up for those parameters?
