Dockerize python flask api that uses mysql.connector gives ModuleNotFoundError when run the docker image

Question

I created an API using python3.7 flask and MySQL. I simply want to dockerize it. I was able to successfully create a docker image. But it throws ModuleNotFoundError: when I run it.

Docker File

FROM python:3.7.4-buster
COPY ./ /app
WORKDIR ./app
RUN pip install -r requirements.txt
ENTRYPOINT ["python3.7"]
CMD ["app.py"]

requriments file

pandas==0.25.1
pymongo==3.9.0
Flask==1.1.1
SQLAlchemy==1.3.8
mysql_connector_repackaged==0.3.1

Docker Image built successfully. However when I run the docker image. I get the following error.

$ docker run -p 5000:5000 api_module:latest
Traceback (most recent call last):
