Das System (in diesem Fall **FastAPI**) kümmert sich dann darum, Ihren Code mit den erforderlichen Abhängigkeiten zu versorgen („die Abhängigkeiten einfügen“ – „inject the dependencies“).

Das ist sehr nützlich, wenn Sie:

* Eine gemeinsame Logik haben (die gleiche Code-Logik immer und immer wieder).

### Specifying Python dependencies

During bazel build all TensorFlow's Python dependencies are pinned to their
specific versions. This is necessary to ensure reproducibility of the build.
The pinned versions of the full transitive closure of TensorFlow's dependencies
together with their corresponding hashes are specified in
