MemoryError: std::bad_alloc in pickling

Hello,
I encountered a memory error message on this mpi tutorial https://docu.ngsolve.org/latest/i-tutorials/unit-5a.1-mpi/poisson_mpi.html in block [5] when running the line gfu = c[:]["gfu"]

The error message seems to be related to parmetis partitioning as it first appeared on the netgen update commit
d926f7198e33c762936065b9e5a1dc15e2d94734 (update netgen (partitioning))

Best,
