Optimization of self.cI

[NoraAl]

Thank you for sharing the reimplementation and for the clean and organized code. There is an issue with the state of the meta learner self.cI. It is created as a parameter of the metalarner, and thusly getting optimized by Adam here. It should be passed as a state to avoid such behavior.

Thanks

A quick fix is to freeze those parameters to avoid potential updates. A pull request has been created.
