Making a submission with a macOSx?

Participants should be able to make a valid submission with macOS (in fact simply from their browser, if they fork the repository, change the code using the web IDE and release a tag). For evaluating an already trained model, we use disentanglement_lib which depends on tensorflow. Thus to evaluate the submissions locally on macOS using, one needs to install the CPU version of tensorflow as tensorflow doesn’t provide GPU support for macOS. To do this, simply replace tensorflow-gpu with tensorflow in the requirements.txt.
