When running my module directly with as a flask app through Docker with Python 3, which installs pandas based on the requirements.txt file, it runs fine. When I import this module from another app, it doesn't find pandas. The following is my setup.py file.
from setuptools import setup, find_packages
with open('requirements.txt') as f:
required = f.read().splitlines()
setup(
name='g_plotter',
packages=find_packages(),
#packages=['g_plotter', 'pandas'],
include_package_data=True,
""" install_requires=[
'flask',
], """
install_requires=required,
)
Failure at:
import pandas as pd
Traceback
server_1 | File "./g_server.py", line 21, in <module>

In Docker I don't see pandas being installed:

The problem was that I had two setup.py files. One at the root and one in the subdirectory with the rest of the code. I was updating the inner one. Once I move that up and replaced the old one, all the dependencies got installed.
