OmegaConf Structured Configuration Error in SHAPY

[patelkunjanp]

I'm trying to run the SHAPY demo script with:

bash
python regressor/demo.py --model-folder $SMPL_MODEL_PATH --gender="neutral"
But I'm getting an assertion error in OmegaConf:

text
AssertionError: assert self.element_type is Any or isinstance(self.element_type, type)
The error occurs in network_defaults.py line 269 with conf = OmegaConf.structured(Network).

Environment details:

Python 3.8

OmegaConf (current version)

SHAPY repository cloned from GitHub

Running in WSL2 Ubuntu environment

I've already successfully run a simplified SMPL-X demo script, but the original SHAPY demo fails with this configuration error.

Has anyone encountered this issue with OmegaConf's structured configs in SHAPY? Are there known compatibility issues between certain versions of OmegaConf and

shapy_Error_Omegaconf.txt

Python 3.8?

Any solutions or workarounds would be greatly appreciated!
