Error in importing the package

[Mojzaar]

when I use: import pyclesperanto_prototype as cle I get this error:

---

If I interpret the information here correctly, this means the version of pyopencl you have installed is only compatible with Python 3.9. Can you follow the installation instructions here and try again?

I presume this was solved. If not, please create another issue.
