My accuracy scores are above the threshold but I am receiving an error

When I upload the .plk file after receiving above the threshold in validation and training accuracies I receive an error:
“Failed test case: could not parse values for training accuracy from history.”
Could somebody please help me fix what might be going wrong here?

Hi @Aidan_O_Sullivan, that looks weird, can you DM me with the .pkl file that you uploaded?

Great thank you, messaged

If anyone else is facing this error make sure you use accuracy instead of acc when defining the metrics during the compiling of the model. The grader currently is only able to handle accuracy. We will patch this in the coming days but until further notice please use accuracy.

Sorry for the inconvenience and thanks to @Aidan_O_Sullivan for reporting!
