Installing and Using Python Modules in a Docker Container

问题

I am new to using docker containers. I have successfully created a new docker container but am now having trouble installing and then using python modules in it.

I entered into the already running container with the following command:

$docker exec -it lizzie /bin/bash

This worked. I also managed to install the module of interest to me with the following command:

$pip install pysnmp

I cloned my git repository, entered the local repo, and attempted to run a script that utilized the module pysnmp. The following error was returned:

ImportError: No module named pysnmp

I reinstalled the module to ensure that it had installed correctly; all requirements were already satisfied. The two folders currently in the docker are a folder called "anaconda-ks.cfg" which I can't enter and the repo. I feel like this has something to do with the path the module was installed in but I'm not sure where I should be installing it or how to do so. Thanks in advance for the help!
