### Updating the playbook for 32-bit Raspberry Pi OS
-Besides `tensorflow` all other dependencies will pretty much work regardless of architecture and python3 version. So to make this playbook work on 32-bit a decision must be made depending on the architecture. On 32-bit a different prebuilt `tensorflow` wheel must be used, as well as another `numpy` version.

So to make this playbook work on 32-bit a decision must be made depending on the architecture. On 32-bit a different prebuilt `tensorflow` wheel must be used, as well as another `numpy` version. No prebuilt wheels were found yet for 32-bit in combination with `python3.9` (debian / raspberry pi os 11), only for `python3.7` which is not compatible with the current version of raspberry pi os.
