Hi @HarryDC, eagle eyes! Can you post an issue on our github? Thanks for contributing!
Thanks. Now it’s fixed. See comments in https://github.com/d2l-ai/d2l-en/issues/1448
the second traning (use_random_iter=True) uses the model trained by the first time:
(1)the ppl is from about 2.0
(2)the curve is bumpy
I argee with “uses the model trained by the first time”. Thank you for reminding us.
use_random_iter=True maybe is a way to converge better when it is hard to converge our model.
