This code raises error at iteration 69, fixed each time.
Actually, I have run a similar code for several times, and haven’t met this error until recently when I used a new “.rec” file, which is larger than the original ones.
At the beginning, I thought the problem lies in data --raw data or generated rec file. But as I tried some different parameters, I find something really strange.
When I change batch size, the program will break down at a different iteration. (not on the same image)
When I change the "data_shape" parameter to (3, 501, 501), it will also raise an error at another different iteration.
If I let it sleep for one second each iteration, it will break down at another iteration.
Now I believe the problem must lie in the mx.io.ImageRecordIter itself. Does anyone have idea about this strange thing?
