Hey, there seems to be an issue with the Circle CI. Will ping @sgugger for this. 
Can you add the error you are getting on your issue? 
I think we should also add a test to make sure that this model is ran, the fix LGTM 😉 thanks

It seems there is an issue with your CircleCI permissions, the tests won't run.
Could you try refreshing your permissions as shown [here](https://support.circleci.com/hc/en-us/articles/360048210711-How-to-Refresh-User-Permissions-)?

Thanks! Can you now run `make style` to fix the test failure you see on the CI?

@NielsRogge Please help adding the test. I am having limited capacity here.
