Error in train.py

[zqs010908]

Thank you for providing the code. I am trying to use train.by to train my model，but I encountered the following issue while using train.py

Traceback (most recent call last): File "/home/iiau-vln/ws_zqs/nomad/visualnav-transformer/train/train.py", line 402, in main(config) File "/home/iiau-vln/ws_zqs/nomad/visualnav-transformer/train/train.py", line 326, in main train_eval_loop_nomad( File "/home/iiau-vln/ws_zqs/nomad/visualnav-transformer/train/vint_train/training/train_eval_loop.py", line 196, in train_eval_loop_nomad ema_model = EMAModel(model=model,power=0.75) TypeError: init() missing 1 required positional argument: 'parameters'
