Description

TensorFlow 2.0 was released. We should consider upgrading our TF dependency to 2.0.

However, since this is large major version up, we still don't know how much source code needs to be rewritten for the upgrade.

Fortunately, there's a script tf_upgrade_v2.py to upgrade to TF 2.0. First, we should try this script and estimate how the upgrade is difficult.

Research direction
Run the tf upgrade v2.py script on the Blueoil codebase to assess compatibility with TensorFlow 2.0. Document the number of errors and warnings, and identify which modules require significant changes. Review the script's output to estimate the effort needed for a full upgrade.
