No module named 'yaml'

We have been running a lot of issues trying to develop binders using RFdiffusion

we are currently running this on a cloud machine using Nvidia Brev and a Crusoe machine:

OS: Ubuntu 22.04.4 LTS x86_64
Host: cloud-hypervisor
Kernel: 5.15.0-116-generic
CPU: AMD EPYC 9254 (8) @ 2.900GHz
GPU: NVIDIA 0002:00:01.0 NVIDIA Corporation Device 26b9 is currently an L40s
Memory: 927MiB / 147864MiB

Traceback (most recent call last):

    import yaml
ModuleNotFoundError: No module named 'yaml'

It began with hydra issues that dolved after updating cuda, then moved to this error after performing a conda update -all

Start at scripts/run_inference.py and reproduce the import failure in the reported Python 3.9 conda environment. Then inspect the repository's environment or dependency setup for how OmegaConf and its yaml import are provided; the work is done when the entry point starts without this missing-module error.
