Networking in PyCharm
PyCharm requires Internet connection for a wide variety of tasks. For example:
Checking for PyCharm updates
Code inspections that can verify external resources
Communication with the version control servers, task servers
Anonymous usage statistics
Working with remote interpreters
- Installing and upgrading Python packages
Besides that, PyCharm provides IPC for commands (for example, open files), and the built-in Web server.
Some of the communication requirements are configurable:
To turn off checking for updates, open the Settings | Updates page, and clear the Check for updates in channel checkbox.
To disable code inspection that highlights dead links, open the Settings | Inspections page, and clear the checkbox to the left of the HTML inspection Non-existent web resources.
You can control the frequency of sending usage statistics, or even completely disable this function in the page Settings | Usage statistics.
