Hi folks, which Python version should I use to create a demo Rasa bot? I´m following the steps described on the documentation and also steps from a video that I found on Vimeo (published by Justina Petraityte), but I get an error when I run the command “python nlu\_model.py”… I´m using Python 3.6.5 x64 for windows on a Windows Server 2012 R2.

The only version that worked properly for me on a MacBook was 3.5

You should download and **install** the latest version of Python. The current latest (as of Winter 2019) is Python 3.7.2. Remember that you must **install** Java, Python, and Eclipse as all 32-bit or all 64-bit.
