Upgrading from Ray 1.11 to Ray 2.0.0

How severe does this issue affect your experience of using Ray?

  • Medium: It contributes to significant difficulty to complete my task, but I can work around it.


is there a way to upgrade from Ray 1.11 to Ray 2.0.0. It seems many things have changed, and it’s not entirely clear the exact modification of each component of code that may be causing a certain issue. Is there a way to do this systematically? Some place where I can compare the exact changes that need to take place? For example, (hypothetically) tune.run() has to now be replaced with tune.run_experiment() and the parameters that have been renamed: …, removed: …, etc.?

There is the Ray 2.0 migration guide: Ray 2.0 Migration Guide - Google Docs
Which can be found on the release notes: Release Ray-2.0.0 · ray-project/ray · GitHub
This helped a lot for me.
