@tahamr83 That’s not the issue, the templates are fine, it helps to be more declarative, and my chatbot has used that template since day one without issue.

@mirzahash The issue you’re having is due to using Python 2.7, I’d recommend you reinstall with python3 (3.6 works best) and try that make command again. If you look at the error logs, your Python 2.7 installation is being used instead of your 3.6 since the make commands invoke that version.

What I’ve done to help just prevent that issue from happening in the first place is either alias all python2 commands as python 3 commands in your .bashrc, or just start running the training inside Docker containers, as described here.

Here’s what my .bashrc looks like (this is not ideal and I’d strongly recommend using Docker containers):

alias python=python3.6
alias pip=pip3
