Broken install on alpine docker

Created by: danlkv

Using this Dockerfile, deeppavlov installes, but the installation seems to be broken

from python:3.7-alpine
run apk add g++ python3-dev git make cmake

# Use wheels, because building scipy from source is a pain. https://github.com/pypa/pip/issues/3969
run echo "manylinux1_compatible = True" >> /usr/local/lib/python3.7/_manylinux.py
run pip3 install deeppavlov
run python3 -c "from deeppavlov import train_model"

I get error on last command ImportError: cannot import name 'train_model' from 'deeppavlov' (/usr/local/lib/python3.7/site-packages/deeppavlov/__init__.py)
