AttributeError: 'LambdaLR' object has no attribute 'get_last_lr'

See original GitHub issue

I am trying to run the summarization example using BART and getting the following error.

tqdm_dict = {"loss": "{:.3f}".format(avg_loss), "lr": self.lr_scheduler.get_last_lr()[-1]}
AttributeError: 'LambdaLR' object has no attribute 'get_last_lr'

The error occurred at this line. I am using PyTorch 1.3.

Upgrading to PyTorch 1.4 would solve that issue 😃

Current master branch recommends that:

I upgraded pytorch to v1.5.0, but run_glue.py with Bert model failed. So, you may have to set it to 1.4.0
