how to solve this problem?

[Steven-Xiong]

While training python train.py --config configs/config.py , I meet this problem:

Traceback (most recent call last):
File "train.py", line 150, in
main()
File "train.py", line 55, in main
train(config, device, args.save_checkpoint)
File "train.py", line 101, in train
train_dataset, val_dataset, test_dataset = make_dataset(config, train_transform, val_transform)

datasets = get_datasets(config)

raise AttributeError(
AttributeError: 'AttrDict' instance has no attribute 'train_params'
I have changed the root dir of the three datasets.

error is easy. I have fixed. you can ignore 'external_train': partial(external_reader, **config.external.train_params)
