del cos_scores

Hi,
This seems like a trivial question but why is the cos_scores variable being explicitly deleted? If I'm not wrong, the garbage collector will clear that memory since it's a local variable in a loop that goes out of scope?

Not sure if it is needed. But sometimes there are be issues with out-of-memory

Hello!

#2381 has removed this del, which should indeed not be necessary.
