 Next, you'll need to clone the [Tensorflow Repo](https://github.com/tensorflow/tensorflow) at the desired checkout (using TF head isn't advised). If you are planning to use libcoral or pycoral libraries, this should match the ones in those repos' WORKSPACE files. For example, if you are using TF2.15, we can check that [tag in the TF Repo](https://github.com/tensorflow/tensorflow/tree/r2.15) get the latest commit for that stable release and then checkout that address:
 ```
 git clone https://github.com/tensorflow/tensorflow
-git checkout r2.15
+git checkout v2.16.1
