Description
The default `ray[rllib]` version is 0.8.5. How can I change it to 0.8.6? I've associated my own code to the notebook instance and specified `ray[rllib]==0.8.6` in `requirements.txt` as [this instruction](https://www.aicrowd.com/challenges/neurips-2020-procgen-competition) suggests. But it does not work. I also tried to call `pip install ray[rllib]==0.8.6` inside the python script. It gives me the following error message

Research direction
No source files or tests are named. Start by reproducing the notebook setup and compare the Ray version installed through requirements.txt or pip with the version used to start the cluster. Done means the cluster and the process on the node run the same Ray version without the mismatch error.
