AutoNlp model training Error

Hello Everyone
I am using AutoNlp to train a model for token classification, but when ever i reach the training step after the training start, it stops suddenly and I get a status Done with Error.
Does anybody know why its is happening?
I tried training a model with a dataset that i had earlier, and had trained a model using AutoNlp. But now it is giving an error even for that.

Is there a stacktrace?

No. Unfortunately, AutoNLP does not give any stack trace.
