Hello guys. Kudos for the launch.

How much effort is needed to resolve this issue ?
What do you guys think?

Just find the project and first great job. I've been looking for something like this. On the issue, I might be able to help. Progressbar surely does not work in python3 but there is Python3 fork EDIT fork not been updated in 4 years... maybe progressbar2 3.11.0 instead beside that let's see what happens when I run 2to3 on the project. I am not 100% if I have time this but here is a fork https://github.com/HintikkaKimmo/rasa_nlu , I make pull once I get it to work, right now its pile of type errors...

Ok it's now running on Python 3.5.2 but bit of a hack

Could someone give a little direction here, Admittedly I only spend about an hour to migrate a rather sizable project and got it running (2 tests are still failing due to type issues). However, my quick fork wouldn't work with Python 2.7, because I did not write backward compatible way and one of the dependencies progressbar was changed to progressbar2. Is there a plan to make the whole project run on both python versions?

If that is the case I can start to contribute small commits file by file, but I have no idea what to do with progressbar and how to make it handle byte data allowing Python2 to still understood what is happening.

Hi Kimmo, thanks very much for looking into this. We can replace progressbar with tqdm . I will try to find someone who can help make the code cross-compatible as well.

Is there any branch, issues, or something to help with?
