allennlp.common.checks.ConfigurationError: key "dataset" is required at location "data_loader." #2
Description
Hello, I'm trying to run the training procedure allennlp build-vocab ... and allennlp train ..., but got an error:
Traceback (most recent call last):
File "/home/ubuntu/miniconda3/envs/thor/lib/python3.8/site-packages/allennlp/common/params.py", line 238, in pop
value = self.params.pop(key)
KeyError: 'dataset'
During handling of the above exception, another exception occurred:

allennlp.common.checks.ConfigurationError: key "dataset" is required at location "data_loader."
This error occurs at both build-vocab and train phase. I'm not familiar with allennlp. If I add "dataset": "alfred" into the "data_loader" field, a more confusing error occurs:

Is there any solution for this error?
