(At the time of writing, there seems to be a bug in how the cuda builds are resolved by mamba, defaulting to cudatoolkit==10.2; thus, it is prudent to be as explicit as possible like above.)

 For context, installing TensorFlow 2.7.0 with ``CONDA_CUDA_OVERRIDE="11.2" mamba install tensorflow==2.7.0=cuda* -c conda-forge`` results in approximately 2 GB of packages to download while ``CONDA_CUDA_OVERRIDE="11.2" mamba install tensorflow=2.7.0=cpu* -c conda-forge`` results in approximately 200 MB to download. That is a significant bandwidth and storage wasted if one only needs the ``-cpu`` variant!
