 ## Notes
 
-This repo makes use of PyTorch (`torch` and `torchvision` packages) CPU-only version. In order to support installing PyTorch via poetry for various environments, we specify the exact wheels for each environment in the pyproject.toml file. Some background reading on why this is required can be found here: https://santiagovelez.substack.com/p/how-to-install-torch-cpu-in-poetry?utm_campaign=post&utm_medium=web&triedRedirect=true

 ## Troubleshooting
 
-### Poetry Installation Issues
+### Dependency Installation Issues
 
-**Problem**: `poetry install` fails with dependency conflicts
-**Solution**: Try updating Poetry first with `pip install --upgrade poetry`, then run `poetry update` followed by `poetry install`
+**Problem**: `uv sync` fails with dependency conflicts
+**Solution**: Try updating uv first with `uv self update`, then re-resolve with `uv lock --upgrade` followed by `uv sync`
 
 **Problem**: Package installation errors
-**Solution**: Check your Python version matches the one specified in `pyproject.toml`. You can use `poetry env use python3.x` to set the correct version.
+**Solution**: Check your Python version matches the one specified in `pyproject.toml`. `uv python install` will fetch the right interpreter, and `uv sync` builds the environment against it.
