Out of Memory CUDA Error with Increased Data Size in BERT4Rec

[tina9309]

I initially tested the functionality with one day’s worth of my custom data, and successfully trained and evaluated BERT4Rec without any issues.
However, when I tried to input a week’s worth of data for additional training, I encountered an out of memory CUDA error.

By reducing the 'bert_max_len' and 'batch size' in the 'templates.py' file, I managed to get it to work, but I do not understand why the increase in data size would cause an out of memory error.

Is there a part of the code where the increased data size might be impacting memory usage?
If so, could you point out where this might be occurring?

Thank you for your assistance.
