 > [!NOTE]
 > If running on an Intel mac, you may get errors related to torch/torchvision versions. Conda maintains updated versions of these packages. You will need to create a conda environment and run `conda install 'torchvision>=0.22.0'` (this should also install pytorch and torchvision-extra). Then, you should be able to run `uv pip install mellea`. To run the examples, you will need to use `python <filename>` inside the conda environment instead of `uv run --with mellea <filename>`.
