/home/runner/miniconda3/lib/python3.12/site-packages/conda/base/context.py:201: 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(

The 'defaults' channel might have been added implicitly. If this is intentional, add 'defaults' to the 'channels' list. Otherwise, consider setting 'conda-remove-defaults' to 'true'.
