Streamz + hvplot seems fairly broken (any alternatives?)

Hey @dharhas!

Nice to see you’re trying out the streaming capabilities of hvPlot. I’m not surprised there’s some issue though, I think it’s not the most tested part of our system, but it’s something we could improve with some feedback. And it’s good to know people are using it, it helps up prioritize work!

On the issues that you hit, just to complement what Simon already said:

  • Support for Python 3.11: it’s coming, we’ve made some changes to Param (available in a dev release) and to HoloViews (not yet released). The ecosystem on which is not yet fully compatible with Python 3.11. Most notably when I tried to run HoloViews’ test suite on Python 3.11 Numba wasn’t yet available.
  • The latest release of ipykernel broke more projects than us. It was quickly yanked on PyPI but (yet?) removed from conda-forge.
  • The Pieces mismatches error comes from a bug in IPython. We’ve made a change in Param to work around that bug (not yet released)
