Welcome to the forums! It might be worth checking out this post to improve your chance of getting a useful answer.
In this case, I think you’ll need to provide a lot more context for your question. What problem are you trying to solve? What package in Julia are you using? Do you have some code you can share?
You don’t mention what package the function you’re interested in comes from in python for example, nor what it does. There may not be (I would say probably isn’t) an exact replicate, but if you describe what you’re trying to do you may be pointed to analogues that accomplish the same thing or something similar.
