Using Tensorflow gives 502 Bad gateway error

I have code in the backend of django project which is hosted on PythonAnywhere that uses tensorflow. However, I am getting this error in server log and a 502 Bad Gateway server error

Please let me know how to use tensorflow on pythonAnywhere or any configurations i have to add.

Thanks

Hmm, does follow these instructions for a notebook work for you?
