title: AttributeError: module 'tensorflow.python.training.checkpointable' has no attribute 'CheckpointableBase'
body: <p>I've been working on learning artificial intelligence and how to code with Python.I was working on a project and I decided to update some packages of Python which were not new to work on then something happened and I can't compile my codes.I deleted Anaconda3 and set it up again but not worked. I've been seeing this problem which I wrote as a topic.If someone helps me,I would be appriciated to get some help.</p>
