there is something wrong happened, this is the wrong code:

Usage: pip [options]

Invalid requirement: --allow-external keras
pip: error: no such option: --allow-external

If you want to use the Interactive_NMT branch, you should download my fork of Multimodal_keras_wrapper, from https://github.com/lvapeab/multimodal_keras_wrapper.git. Indeed, there's a wrong link in that README, I'll fix it.

It seems the --allow-external was deprecated in pip. I've just updated the file.

Try to run again:
git clone https://github.com/lvapeab/multimodal_keras_wrapper.git
and
pip install -r requirements.txt
