I have two Tensors,a and b,a is a top-k tensor, b is the mask tensor. a's shape is [batch_size, k],b's shape is [batch_size * seq_len], dtype is bool ,initialized all by False. each row of a has k integers, each integer' value i means that , the i'th item of the corresponding raw of b should be set to True.
For example:
b is [[False,False,False,False,False],[False,False,False,False,False]].
a is[[0,4],[1,2]] , set the corresponding index of a in b to be True.
then the result is [[True,False,False,False,True],[False,True,True,False,False]].

Welcome to StackOverflow! In order for people to help you, you'll need to be a bit more clear in what your question is (from what you have here, it sounds like you're asking someone to write code -- possibly homework -- for you, which is not what SO is for). If you can post some code demonstrating what you've tried and describe where you're having issues, you'll be more likely to find someone that can help you.
