// TODO(you): code here to reproduce the problem
I have been trying to get this lib to work for three days. I have tried python 3.5, 3.6, 3.7, and 3.10.
I have tried installing pytext using conda, pip, and build from source.

googling ends up in dead trails where people continue to see the same problem, but previously raised tickets are closed.

Please give indication how to get past this step?

I get the same error following the README in this repo by running

pytext export < demo/configs/docnn.json
