 For context, installing the TensorFlow 2.7.0 CUDA-enabled variant, ``tensorflow==2.7.0=cuda*``, results in approximately 2 GB of packages to download while the CPU variant, ``tensorflow=2.7.0=cpu*``, results in approximately 200 MB to download. That is a significant bandwidth and storage wasted if one only needs the ``-cpu`` variant!
