OK actually just solved this. Follow this guide to setup jemalloc: https://zapier.com/engineering/celery-python-jemalloc/ [zapier.com]
Then if you run external python as suggested importing Hou module won't error about jemalloc. As of writing this latest jemalloc is 5.2.1 so worth getting latest and changing bash commands appropriately:

However DLFCN was deprecated in py 3.6, so just change:

I'm seeing this as well on Houdini 19 / Ubuntu 20.04.
In my case I have to user an external interpreter (Py 3.7.12 from deadsnake)since gRPC won't import into Hython with ctype errors.

Anyone using gRPC with hython/ hou python on linux? Feb. 8, 2022, 1:02 p.m.
Hi all, experimenting with the Dapr library which uses gRPC. Unfortunately there's some weirdness with different gRPC versions and py 3.7.x
Anyone manage to get gRPC working?
Thanks!
