DR-GAN extractor not available ?

Hey @amohammadi @tiago.pereira

Just installed the package (conda install bob.ip.tensorflow) to prepare an environment for the FARGO project. For some reason, the class DrGanMSUExtractor is not available, and I don't know why, since it is here:

https://gitlab.idiap.ch/bob/bob.ip.tensorflow_extractor/blob/master/bob/ip/tensorflow_extractor/__init__.py#L69

Here's the error I get:

from bob.ip.tensorflow_extractor import DrGanMSUExtractor
ImportError: cannot import name 'DrGanMSUExtractor'

Do you have any idea about this ?

Thanks !
