Issue with CySimpleEllipseDispatcher During Test Case Execution

[Btushir]

I am currently testing the RidePy project and have encountered an issue with the CySimpleEllipseDispatcher during the execution of the test case test_same_location_with_detour. The installation was verified following the instructions provided, but the test case fails with an assertion error. I would really appreciate if you could please help me resolve this: Below are the details:

Environment
OS: macOS
Python Version: 3.9.19
RidePy Version: Latest from the repository
Below is the output of the test case:

Thanks for posting this, looks strange indeed. I will look into this.

@fxjung Thanks. Looking forward to it. Let me know if you need more information.

I have just tried to reproduce the problem, and unfortunately failed. Under Linux, using the exact same Python version, the test passes. Have you created a fresh virtual environment? If not, you could try to do so. Also, if you have a Linux or Windows installation at hand, you could try to see whether the error persists there.

Could you please post the output of pip freeze in the environment you were using? Maybe this caused by some change in a third-party package...
