Generates a random samply as index tensor with a mask tensor from a given tensor. Generates a random samply as index tensor with a mask tensor from a given tensor.
The input must be a tensor of rank >= 2, the first dimension specify the number of sample. The input must be a tensor of rank >= 1. If its rank >= 2, the first dimension specify the number of sample.
The index tensor and the mask tensor have the same and fixed shape. The index tensor denotes the index The index tensor and the mask tensor have the fixed shapes. The index tensor denotes the index of the nonzero

Args: Args:
count (int): Number of items expected to get. Default: 256. count (int): Number of items expected to get and the number should be greater than 0. Default: 256.
seed (int): Random seed. seed (int): Random seed. Default: 0.
seed2 (int): Random seed2. seed2 (int): Random seed2. Default: 0.
Inputs: Inputs:
- **input_x** (Tensor) - The input tensor. - **input_x** (Tensor[bool]) - The input tensor.
Outputs: Outputs:
Tuple, two tensors, the first one is the index tensor and the other one is the mask tensor. Two tensors, the first one is the index tensor and the other one is the mask tensor.
- **index** (Tensor) - The output has shape between 2-D and 5-D.
- **mask** (Tensor) - The output has shape 1-D.
Examples: Examples:
>>> rnd_choice_mask = RandomChoiceWithMask() >>> rnd_choice_mask = RandomChoiceWithMask()
