ModuleNotFoundError: No module named 'pandas' when importing module

问题

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>
server_1  |     from g_plotter import Gparser
server_1  |   File "/usr/local/lib/python3.7/site-packages/g_plotter/Gparser.py", line 4, in <module>
server_1  |     import pandas as pd
server_1  | ModuleNotFoundError: No module named 'pandas'

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.
