Future Miniforge releases will NOT build Mambaforge installers. We advise you switch to Miniforge at your earliest convenience. More details at https://conda-forge.org/news/2024/07/29/sunsetting-mambaforge/.

/Users/runner/miniconda3/lib/python3.12/site-packages/conda/base/context.py:200: FutureWarning: Adding 'defaults' to channel list implicitly is deprecated and will be removed in 25.3. To remove this warning, please choose a default channel explicitly with conda's regular configuration system, e.g. by adding 'defaults' to the list of channels: conda config --add channels defaults For more information see https://docs.conda.io/projects/conda/en/stable/user-guide/configuration/use-condarc.html deprecated.topic(

Mamba support is still experimental and can result in differently solved environments!
