How to check if PyCharm Cython speedups are installed?

Question

PyCharm usually gives a notification when debugging saying "Python Debugger Extension Available".

I'm not sure I have them installed or not. How can I check if they are?

I'm on:

• PyCharm 2023.1
• Ubuntu 20.04

This popup suggests installing debugger extensions, meaning PyCharm doesn't find any. Hence you have none.

One way to double-check if the debugger is using them or not is to add the PYCHARM_DEBUG=True environment variable to some Python run configuration (Run -> Edit Configurations)

Then run the configuration under the debugger and check for Using Cython speedups in the Debug toolwindow output.
