@spiermar , can you explain this issue a bit? Or could you redirect me to sources reading which would make me understand?

I want to contribute.

@avisrivastava254084 already solved in the feat_differential_flame_graphs branch. Just need to run a few tests before merging into master. In a nutshell, the new feature adds support for comparing flame graphs through differential flame graphs. If are looking to start contributing, two issues we are actively looking right now are #69 and #39. Happy to share more details about it.

@spiermar I hit the following error from the feat_differential_flame_graphs branch when running python run.py. Any idea why? Thanks

No need to use the branch anymore. It was already merged into master. And the issue was caused by the python version you are using.
