I have an issue when trying to visualize the dataset I generated synthetically with the synthetic data generation tool provided by this repo. I run the notebook inspect_dataset and get following error in the second cell:

I think there is a problem with the structure of the YAML file. When I delete !!python/object:argparse.Namespace in the first line and !!python/object/apply:pathlib.PosixPath in the third line inside the YAML file of the dataset, I get following error:
When I try to validate the content of the YAML file with https://codebeautify.org/yaml-validator, I get errors in both versions. I think there is something with the !! expressions. While python seems to not have a problem with these expressions when I remove the two lines mentioned above, but rather has a problem with the content of file, it cant find the scene_kwargs attribute.
Any help is appreciated. Thanks in advance

Hi @tensarflow,
I had the same error. To fix it, change self.cfg = yaml.load((ds_dir / 'config.yaml').read_text(), Loader=yaml.FullLoader)
to self.cfg = yaml.load((ds_dir / 'config.yaml').read_text(), Loader=yaml.UnsafeLoader)
in datasets/synthetic_dataset.py.
It works with the provided YAML file and you don't have to delete any lines in the files.
Hey everyone!
