• pytorch的linspace, rand, randn, normal


    torch.linspace

    torch.linspace(start, end, steps) returns a one-dimensional tensor of equally spaced points between [start, end]。steps默认值是100。

    torch.rand

     torch.rand(size) returns a tensor filled with random numbers from a uniform distribution on the interval [0, 1).

    torch.randn

    torch.randn(size) returns a tensor filled with random numbers from a normal distribution with mean `0` and variance `1` (also called the standard normal distribution).

    torch.normal

    torch.normal returns a tensor of random numbers drawn from separate normal distributions whose mean and standard deviation are given.

    The arguments `mean` is a tensor with the mean of each output element's normal distribution.

    The arguments `std` is a tensor with the standard deviation of each output element's normal distribution.

    torch.normal的参数给定方法有很多种:

    第一种:给定mean (Tensor)和std (Tensor)

     第二种:给定mean(float)和std (Tensor)

    第三种:给定mean (Tensor)和std (float),std也可不给,若不给定,则默认为1.0

     第四种:给定mean (float)、std (float)和size(int...)
