Hi! Greenlet 3.0.3 was released just a couple weeks ago. Can you try installing greenlet 3.0.2? Or install using --no-binary gevent

Or perhaps this is an anaconda-specific problem.

Hi, I have tried install greenlet 3.0.2 or reinstall gevent with --no-binary, this problem still exists.

And if I change a device, locust -V works well.

So maybe it's indeed a anaconda-specific problem.

Thank you!
