mindspore.numpy.randn(*shape, dtype=mstype.float32)[source]

Returns a new Tensor with given shape and dtype, filled with a sample (or samples) from the standard normal distribution.

Parameters

  • *shape (Union[int, tuple(int), list(int)]) – Shape of the new tensor, e.g., \((2, 3)\) or \(2\).

  • dtype (Union[mindspore.dtype, str], optional) – Designated tensor dtype, it must be float type. Default is mindspore.float32.

Returns

Tensor, with the designated shape and dtype, filled with a sample (or samples) from the “standard normal” distribution.

Raises

  • TypeError – If input arguments have types not specified above.

  • ValueError – If dtype is not float type.

Supported Platforms:

Ascend GPU CPU
