AttributeError: module 'tensorboard.lazy' has no attribute 'lazy_load'

I'm trying to execute this simple code

import gym

from genrl.agents import QLearning
from genrl.trainers import ClassicalTrainer

env = gym.make("FrozenLake-v0")

agent = QLearning(env)
trainer = ClassicalTrainer(agent, env, mode="dyna", model="tabular", n_episodes=10000)
episode_rewards = trainer.train()
trainer.plot(episode_rewards)

However, I am getting the error

AttributeError: module 'tensorboard.lazy' has no attribute 'lazy_load'

I had installed this package with

pip install genrl

And I remember there were some incompatibility issues. I am getting now the same error messages after having reinstalled tensorflow-tensorboard and tensorboard, as suggested in this answer.

genrl 0.0.2 requires certifi==2019.11.28, but you'll have certifi 2020.6.20 which is incompatible.

genrl 0.0.2 requires six==1.14.0, but you'll have six 1.15.0 which is incompatible.

Doing

pip install tensorflow-tensorboard==1.5.1

and then

pip install tensorboard==1.15.0

Actually, that solved this issue AttributeError: module 'tensorboard.lazy' has no attribute 'lazy_load', but I think you should be aware of it, and that people can encounter it, as I did, while using your package.
