[object Object]

[object Object][object Object]undefined[object Object]

• Description: Draws binary random numbers ([object Object] or [object Object]) from a Bernoulli distribution. [object Object] indicates the probability of generating [object Object]. The input tensor is used to specify the shape.

• Formula:

  $$out∼Bernoulli(prob)$$

  When [object Object] is used, [object Object] and [object Object] in the formula correspond to those in the prototype of the first-phase API. When [object Object] is used, [object Object] and [object Object] in the formula correspond to [object Object] and [object Object] respectively in the prototype of the first-phase API.

[object Object]

• [object Object] and [object Object] implement the same function in different ways. Select a proper operator based on your requirements.

  • [object Object]: An output tensor object needs to be created to store the computation result.
  • [object Object]: No output tensor object needs to be created, and the computation result is written in place to the input tensor's memory.

• Each operator has calls. First,·[object Object] or [object Object] is called to obtain the workspace size required for computation and the executor covering the operator computation process. Then, [object Object] or [object Object] is called to perform computation.

• Parameters:

  • [object Object] (void*, input): address of the workspace to be allocated on the device.
  • [object Object] (uint64_t, input): size of the workspace to be allocated on the device, which is obtained by calling [object Object].

• Deterministic computation:

  • [object Object] and [object Object] each default to a deterministic implementation.

• The values of elements in the input [object Object] must be within the range [0, 1].

• When the shapes of [object Object] and [object Object](or [object Object]) do not match, only the corresponding elements are computed, and the behavior for the remaining data is undefined. For example, when the shape of [object Object] is [4, 2] and that of [object Object] is [4, 4], only the first 8 elements are computed and the output shape is [4, 4]. When the shape of [object Object] is [4, 4, 2] and that of [object Object] is [4, 4], only the first 16 elements are computed and the output shape is [4, 4].
