training issues

[sepideh-srj]

Hi,
I want to can continue training on a pretrained model provided in the resources, is that possible?
I used the run_training script with all of the flags and gave my 'PYTORCH_WEIGHTS.tar' which was converted using convert_weights script.
I am getting the following error:

line 298, in load_checkpoint
 self.optimizer.load_state_dict(state['optimizer'])
AttributeError: 'NoneType' object has no attribute 'load_state_dict'

I also tried to train from scratch but I get this error:

line 198, in train
    self.optimizer.zero_grad()
AttributeError: 'NoneType' object has no attribute 'zero_grad'

Can you help me with these issues please?
Thank you so much.

Can you tell me exactly how you ran the run_training script? (with a list of all parameters).

I have the same issue and ran:
python3 scripts/run_training --config config/default.json --data-dir data/train --checkpoint-dir checkpoints --log-file log.txt --iterations 10 --iterations-till-checkpoint 2
