What I did:

Upgraded from tensorflow 2.2.0 to tensorflow 2.3.0

Implementation:

from tf_agents.agents.dqn import dqn_agent

You probably need a newer version of tf-agents, e.g., the nightly or most recent release. Each stable version of tf-agents is associated with a stable version of tensorflow; likely updating tensorflow broke the guarantees. Please reopen if that doesn't help.
