mindspore.ops.Dropout

class mindspore.ops.Dropout(keep_prob=0.5, Seed0=0, Seed1=0)[source]

During training, randomly zeroes some of the elements of the input tensor with probability 1-keep_prob from a Bernoulli distribution.

Parameters

  • keep_prob (float) – The keep rate, between 0 and 1, e.g. keep_prob = 0.9, means dropping out 10% of input units. Default: 0.5.

  • Seed0 (int) – Seed0 value for random generating. Default: 0.

  • Seed1 (int) – Seed1 value for random generating. Default: 0.

Inputs:

  • x (Tensor) - The input of Dropout, a Tensor of any shape with data type of float16 or float32.

Outputs:

  • output (Tensor) - With the same shape and data type as x.

  • mask (Tensor) - With the same shape as x.

Raises

  • TypeError – If keep_prob is not a float.

  • TypeError – If Seed0 or Seed1 is not an int.

  • TypeError – If dtype of x is neither float16 nor float32.

  • TypeError – If x is not a Tensor.

Supported Platforms:

Ascend GPU CPU

Examples

>>> dropout = ops.Dropout(keep_prob=0.5)
>>> x = Tensor(((20, 16), (50, 50)), mindspore.float32)
>>> output, mask = dropout(x)
>>> print(output.shape)
