Hi, I'm just wondering why when stream is not None, memory_usage return None ?
https://github.com/pythonprofilers/memory_profiler/blob/a99a3c3b3c2eb01c90f6e14ddfcb85b3e97f9885/memory_profiler.py#L478C6-L478C6

I'm using stream + retval so my script is crashing since i'm getting a None object when doing
mem_usage,res=memory_usage((func,args,kwargs),stream=True, retval=True

My current fix is just removing the if stream : return None, but I would like to know if it will bite me later or if it's fine ?
I'm really not familiar with memory usage so maybe there is a specific reason.
Thanks
