If I remember correctly, libraries imported before the call of `grass.parser()` are imported also during the installation through `g.extension` because of checks or something and you really don't want to import quite heavy TensorFlow (which is moreover printing some warnings during the import on most of computers) making your installation slow. The same applied to the double import when running the script.
