Function Description

• Operator function: returns random numbers drawn from the discrete uniform distribution over the range [from, to - 1].
• Computation formula:

  $$output[i]=X\%(to-from)+from$$

  Here, X is a uint32 random number generated by the Philox random number generator.

Parameter Description

Parameter Name	Input/Output/Attribute	Description	Data Type	Data Format
shape	Input	Shape dimensions of the output tensor.	INT64	ND
seed	Input	Random number seed.	INT64	ND
offset	Input	Random number offset, which must be a multiple of 4.	INT64	ND
from	Input	Optional parameter, which is the lower bound of the random number range.	INT64	ND
to	Input	Optional parameter, which is the upper bound of the random number range.	INT64	ND
y	Output	Output tensor, which contains random values within the specified range.	FLOAT, FLOAT16, BFLOAT16, INT64, INT32, INT16, INT8, UINT8, BOOL	ND
dtype	Attribute	Data type of the output tensor.	DataType	-

Constraint Description

• offset is a multiple of 4.
• The output tensor supports 0 to 8 dimensions.
• from must be less than to. The range specified by from/to-1 cannot exceed the range of the self data type.

Invocation Description

Invocation Method	Sample Code	Description
aclnn invocation	test_aclnn_inplace_random	Invokes the StatelessRandom operator through the aclnnInplaceRandom or aclnnInplaceRandomTensor API.
Graph-mode invocation	test_geir_stateless_random	Invokes the StatelessRandom operator by building a graph through the operator IR.
