Fine tuning KnowBert for downstream tasks

Hi, I am trying to run the below code for fine-tuning KnowBert for Tcred dataset:

allennlp train --file-friendly-logging --include-package kb.include_all \
training_config/downstream/tacred.jsonnet -s OUTPUT_DIRECTORY

I met several errors, I was able to resolve some of them. But not sure how to deal with the below error:

Traceback (most recent call last):

My current environment has passed the tests and I am able to run the example to embed the sentences.
