While writing this book, TensorFlow r1.13 was available. Revision 2.0.0 is also available on the alpha stage, but we will stay with a stable version. The TensorFlow Hub has a dependency on the TensorFlow library that can be installed with pip, as follows:

$ pip install tensorflow
$ pip install tensorflow-hub

When the tensorflow library is installed, we need to start collecting our image dataset before the training process starts. We need to look into a lot of things before we begin our training.
