Freezing terminal

Hi, I'm running into an issue trying to train a model using the instructions in the repository. Once the weights and biases (wandb) choice comes up, the process seems to not do anything, not even responding to SIGINT. It also does not seem to be training the model, since the system resources are barely used.

See the attached log freeze.log.

I had hoped to use this model as reference point to measure the performance of specific models for Duckietown. If there is a pre-trained model available that would also be great.

Hi, as a quick and dirty fix, I suggest that you comment/delete the WeightsAndBiasesLogger from the list of loggers in experiments/train-rllib.py:

--- a/experiments/train-rllib.py
+++ b/experiments/train-rllib.py
@@ -99,6 +99,6 @@ tune.run(PPOTrainer,
          checkpoint_score_attr="episode_reward_mean",
          checkpoint_freq=1,
          restore=checkpoint_path,
-         loggers=[CSVLogger, TBXLogger, TensorboardImageLogger, WeightsAndBiasesLogger]
+         loggers=[CSVLogger, TBXLogger, TensorboardImageLogger]
          )

I'm not sure why can't the process continue if you don't use wandb, I'll have a look at it later.
