download_datasets

[fighting-j]

Hello, when I follow the installation steps to download the dataset, the following error appears. How can I solve it?

(omnigibson) ubuntu@hjj:~/OmniGibson$ python scripts/download_datasets.py
Requested average specs of the object categories in the OmniGibson Dataset of objects, but the file cannot be found. Did you download the dataset? Returning an empty dictionary

This is interesting, seems like a pymeshlab installation issue. This looks relevant: cnr-isti-vclab/PyMeshLab#341
Do you mind sending your ubuntu version?

[fighting-j]

My ubuntu version is 22.04.

Can you try to just do

import pymeshlab

in your conda environment?

Maybe try to reinstall pymeshlab again?

[hang-yin]

From @cgokmen: This could be a Qt version issue. It seems like pymeshlab expects one version, but you have another one installed.

Closing the issue for now since there is no follow-up. Feel free to re-open if the problem persists.
