Why are these changes needed?
This enables debugging into pickle backend when using Ray (with the usage in the doc). This is very helpful when facing complicated serialization errors.
We removed the last line of code that was added to the original PR (#23854) accidentally. That line of code causes CI failures in windows and macos.
