Rademacher Integration failed

Hi,

I use the Rademacher integration for a long time now without any issued.
But now I can´t use it any more. In the Integration section Iget the message “not loaded”.
Here the logs:

Unable to install package pyrademacher==0.6.6: ERROR: Cannot install pyrademacher==0.6.6 because these package versions have conflicting dependencies. ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/topics/dependency-resolution/#dealing-with-dependency-conflicts [notice] A new release of pip is available: 23.0 -> 23.0.1 [notice] To update, run: pip install --upgrade pip

How can I upgrade pip? It dosn´t work in the Terminal.
