im just trying to cross validate prophet model with paralellizing. i’ve already installed dask and i can view the dashboard. but im getting this err.

Hi @uysal-uysal and welcome to discourse!

Are you running this on a single machine or on a cluster? If you’re running on a single machine, Prophet’s cross-validation may work better by passing parallel="processes", whereas using Dask as a parallel backend may be better suited for a cluster, as noted in this Dask example.

Feel free to provide a minimal reproducer!
