gen2-connector 1.0.0b54

Ray gen2 node provider

Gen2-connector enables Ray cluster to be deployed over IBM Gen2 infrastructure

Use of python virtual environment, e.g. virtualenv is greatly encouraged, to avoid installing Python packages globally which could break system tools or other projects

1. Install Ray release 1.8.0 using pip install ray[default]==1.8.0

2. Install gen2-connector on your machine

pip install gen2-connector

3. Configure ibm vpc

   • Generate API KEY

   • Create/Update security group to have SSH, Redis and Ray Dashboard ports open: 22, 8265 and 6379

4. Create cluster config file

   • Use interactive lithopscloud config tool to generate cluster.yaml configuration file

   pip install lithopscloud
   lithopscloud -o cluster.yaml
   

5. Use generated file to bring ray cluster up, e.g

ray up cluster.yaml

• After finished, find cluster head node and worker nodes ips:

ray get-head-ip cluster.yaml
ray get-worker-ips cluster.yaml

• To get status of the cluster

ray status --address PUBLIC_HEAD_IP:6379

• Use browser to open ray dashboard on PUBLIC_HEAD_IP:8265. Alternatively use ray dashboard to forward ray cluster dashboard to your localhost.

• Submit example task ray submit cluster.yaml templates/example.py
