training process becomes unresponsive halfway through

[JennyVanessa]

Has anyone encountered a similar issue where the training process becomes unresponsive halfway through, with no additional log entries being recorded, yet no error is thrown?

This is a bit strange. Does this problem occurs randomly or at a specific epoch (like E:33 as you show) ?

It is random, when I interrupt the program, it reached this point:

(E:34, S:1 / 200) [Loss = 0.1484] (4.4 samples/sec; 0.916 sec/batch)
(E:34, S:2 / 200) [Loss = 0.1454] (4.6 samples/sec; 0.870 sec/batch)

It appears that the data loading thread is not receiving data and is stuck waiting.
