Describe the workflow you want to enable

I have a lot of data and need to calculate metrics such as accuracy_score, jaccard_score, f1_score, recall, precision etc.

Describe your proposed solution

When I try to calculate these it can literally take days, so i created a small solution which can batch and avg in the end, or for the weighted metrics it can do a weighted avg of each, this accelerated the calculation to just a couple of minutes, because I have a 32 core CPU. I'm willing to contribute with the proper guidance as I'm unfamiliar with the codebase, but I think many people can benefit from this. I'm unsure if there is already a work around of this present in the codebase, but if there is one do let me know, thanks a lot.

Describe alternatives you've considered, if relevant
