Training on Django

[jayavardhanr]

I am just running the command given in the readme file to train the model on django dataset.

. train.sh django

I get the below error. I haven't able to able to fix this. Is the something you faced?
The code runs perfectly for the "hs" dataset.

Hi, the django training script can only be used in the Python2 environment, since the target code to generate in this dataset is written in Python 2.
