Troubleshooting Jupyter Notebook Issues in VS Code: Fixing the ZMQ Library Problem

If you're using Jupyter Notebook within Visual Studio Code (VS Code), you might have encountered a frustrating issue related to the ZMQ (Zero Message Queue) library. This problem can manifest as errors that prevent Jupyter Notebook from running smoothly. In this guide, we will explore how to troubleshoot these issues and get your environment back on track.

Understanding the Problem

Many users have reported encountering DLL problems with the ZMQ library while trying to run Jupyter Notebook in VS Code. This can often lead to confusion and frustration, especially if you're unsure of how to resolve it.
