Both tf1.14 and tf2.0 version hang during training

Hi @610265158, I tried to train FaceBoxes detectors using your implementation. However, both tf1.14 and tf2.0 version hang after training started several hundred iterations. No error messages but losses stopped updating. Do you have any idea what might be the cause? Thank you so much!

It should be the data provider problem, some err may happened there , i guess.
Which dataset do you use?

I am using Wider Face despite that I am training 1-channel grayscale models.

Do you have problem with raw 3-channel data?
You could catch some exception in the data provider， and to find out the problem.
