Hello,

Creating documentation and if this helps others when playing with ray:

On Macbook the firewall needs to be turned off so that the distributed components like Redis and ray processes can talk to each other, To turn off the firewall go to, System Preferences -> security & privacy -> Firewall.

Adding the screenshot of manual accept messages that I was getting repeatedly:

I created a container based on the python:3.9-buster image to run the notebooks.

After cloning the repo into the container and moving to the repo's root folder, I ran the following commands:

python -m venv venv
source venv/bin/activate
python3 -m pip install -U pip
python3 -m pip install -r requirements.txt

The last command threw the following error:

ERROR: Could not find a version that satisfies the requirement ray>=1.2
ERROR: No matching distribution found for ray>=1.2

Using the python:3.7-buster and python:3.8-buster image which comes with python 3.7.10 and python 3.8.9 respectively works fine.

I followed the installation instructions using pip on Python 3.7.

This part of the pi.ipynb notebook:

roots = objgraph.get_leaking_objects()
objgraph.show_refs(roots[:3], refcounts=True)

threw the following exception:

ExecutableNotFound: failed to execute ['dot', '-Kdot', '-Tsvg'], make sure the Graphviz executables are on your systems' PATH

I think we should add getting the graphviz executable as part of the installation process. On ubuntu, it's:

sudo apt install graphviz

the steps to get the executable on other platforms is here.

Hi, was walking thru the tutorial and came across this:
