I got errors when training the code

[jinzhuwei]

When loading the dataset, the code runs until train_set = ConformationDataset(config.dataset.train, transform=transforms) an error occurs

Traceback (most recent call last):
File "/storage/weijinzhu/GeoDiff-main/train.py", line 60, in
train_set = ConformationDataset(config.dataset.train, transform=transforms)
File "/storage/weijinzhu/.conda/envs/geodiff/lib/python3.7/typing.py", line 819, in new
obj = super().new(cls)
TypeError: Can't instantiate abstract class ConformationDataset with abstract methods get, len
