Hello, I wonder if you can help with this error message?

My environment is : tf 0.12.1 python 3.5

I've tried searching on the www but can't find anything to fix it?

Thanks a lot :)

You'll need to either:

Use the tf-0.12 branch
https://github.com/deepmind/learning-to-learn/tree/tf-0.12

use tf 1.0rc1 instead of 0.12.1
https://www.tensorflow.org/versions/r1.0/

[sergomezcol]

Exactly, there were a lot of API breaking changes in TensorFlow 1.0 so the master branch is only compatible with that version. As @normanheckscher suggested, you can either upgrade to the latest version of TensorFlow or use the code in the tf-0.12 branch in this repo.
