when running the tutorial03_rllib, I faced some errors.
At step 4.2 (initializing Flow) the errors are:
2020-05-07 21:43:00,585 INFO node.py:498 -- Process STDOUT and STDERR is being redirected to /tmp/ray/session_2020-05-07_21-43-00_584118_78776/logs.

2020-05-07 21:43:00,827 WARNING services.py:1330 -- WARNING: The default object store size of 5.15 GB will use more than 50% of the available memory on this node (5.98 GB). Consider setting the object store memory manually to a smaller size to avoid memory contention with other applications.
2020-05-07 21:43:00,828 INFO services.py:1475 -- Starting the Plasma object store with 5.15 GB memory using /tmp.
At step 4.4 (Running experiments) a lot of errors processing events (as you can see in the attached screenshots), but the algorithm execution terminates.
How can I face these problems/errors/warnings?
