1. OSError: [Errno 8] Exec format error: ‘/app/app.py’

Please try the following solution mentiones in this github thread:

https://github.com/pallets/werkzeug/issues/1482

Did the same tutorial and found the same issue. This fixed it for me.

I added the following shebang to the top of my app.py script

#!/usr/local/bin/python3

Which then caused permission issues. I then added the following to my Dockerfile before the CMD

RUN chmod 644 app.py

2. AttributeError: ‘LeastSquaresError’ object has no attribute ‘get_init_raw_predictions’

Please try downgrading the version of sklearn to 0.20.2 gets rid of this error.
