torch.randn()是一个用来生成随机数字的函数,这些随机数字满足标准正态分布(0~1)。\[3\]它可以接受一个整数或一个元组作为参数,用来指定生成的随机数字的维度。例如,torch.randn(3)会生成一个包含3个随机数字的一维张量,而torch.randn(3,4)会生成一个包含3行4列的二维张量。\[3\]这个函数的返回值是一个张量,可以通过print函数来打印出来。例如,对于torch.randn(3)生成的张量a,可以使用print("a:",a)来打印出a的值。同样地,对于torch.randn(3,4)生成的张量b,可以使用print("b:",b)来打印出b的值。\[3\]
