就是抽样
a = torch.FloatTensor([[0,0,0,0,0,0,0,100]])
b=softmax(a)
b.multinomial()
Variable containing:
7
[torch.LongTensor of size 1x1]
b.multinomial()
Variable containing:
7
[torch.LongTensor of size 1x1]
b.multinomial()
Variable containing:
7
[torch.LongTensor of size 1x1]
b.multinomial()
Variable containing:
7
[torch.LongTensor of size 1x1]
可见是按b的值也就是概率选的
