# Troubleshooting

#### Bad dependencies resolutions

Make sure to run Python 3.12 and latest version of PIP to prevent dependencies conflicts.

#### No matching distribution found for 'xxx'

Make sure to run the latest version of your operating system.

#### No module named 'xxx'

A `ModuleNotFoundError` indicates that dependencies have not been correctly installed.

#### Module 'xxx' has no attribute 'xxx'

A `AttributeError` indicates that dependencies have not been correctly installed.

#### Protobuf parsing failed

Delete the broken model from the `.assets/models` directory to enforce its re-download.

#### Cannot allocate memory

Memory exceptions during processing are usually cause when the GPU runs out of VRAM.
