Issue: KeyError: 'mc1_targets' for truthfulqa_mc
Root cause: Validation Gap

hi,

i'm trying to run the truthfulqa_mc task but evaluate() is raising a KeyError.

here is the output. thanks!

I am not getting this error when I run it. What branch are you on and what is the exat command you are using?

hi thanks for the reply! i am on the master branch. i am using this file i created to run the `evaluate` function because i am computing results in parallel on a slurm cluster.

@umarbeknasimov Try the `big-refactor` branch instead.

thanks for the response. when i checkout to the big-refactor branch, i get another issue. here's the stacktrace:

@umarbeknasimov Hmm that's strange. Try installing this branch and then rerunning it.

what do you mean by installing the branch? do you mean pip installing the requirements?

Closing as can't replicate on latest `main` branch.
