Hi @R Zo,
So having two environments can be supported in Orion (Prefect 2.0). If you wanted to do this in current Prefect, your best bet is doing 2 Docker images so that you can do two containerized environments, and then splitting those into two subflows. I don’t think you can change environment mid run.
I’d need a traceback to guess about the segmentation fault, but I think it might be Dask+Tensorflow specifically that causes that.
For post two, this seems like the Dask workers may be dying. I would suggest looking at the Dask dashboard to see if you can figure out anything
