@alexiswl Thanks again, cwl-utils version 0.38 has been released, and it contains this PR https://pypi.org/project/cwl-utils/0.38/

I think we should run a try-exception to better inform the user to install with cwl-utils[pretty] if they do try to run cwl-graph-split with the pretty parameter.

Sure, can you send a PR? Then I'll review, merge, and make a new release
