The Python developer community has produced thousands of useful packages that you can incorporate into your own projects. Visual Studio provides a UI to manage packages in your Python environments.

1. Select the **View** > **Other Windows** > **Python Environments** menu command. The **Python Environments** window opens as a peer to **Solution Explorer** and shows the different environments available to you. The list includes both environments that you installed using the Visual Studio installer and those you installed separately. The environment in bold is the default environment that's used for new projects.

For example, select **Open interactive window** and an **Interactive** window for that specific environment appears in Visual Studio.

> You can also open the Python Environments window by clicking on the Solution Explorer window and using the Ctrl+K, Ctrl+` keyboard shortcut. If the shortcut doesn't work and you can't find the Python Environments window in the menu, it's possible you haven't installed the Python workload. See [How to install Python support in Visual Studio](installing-python-support-in-visual-studio.md) for guidance about how to install Python.

A small progress bar may appear underneath the environment to indicate that Visual Studio is building its IntelliSense database for the newly-installed package. The **IntelliSense** tab also shows more detailed information. Note that until that database is complete, IntelliSense features like auto-completion and syntax checking won't be active in the editor for that package.

Note that Visual Studio 2017 version 15.6 and later uses a different and faster method for working with IntelliSense, and displays a message to that effect on the **IntelliSense** tab.

4. With a Python project open, you can also open the Python Environments window from Solution Explorer by right clicking on Python Environments and selecting **View All Python Environments**
5. Looking at the editor window, you'll notice that if you hover over the `numpy` and `matplotlib` import statements that they are not resolved. That's because the packages have not been installed to the default global environment.
## Install packages using the Python Environments window

1. From the Python Environments window, click on the default environment for new Python projects and select the **Packages** tab. You will then see a list of packages that are currently installed in the environment.
