Prototype

C Prototype

        
             aclError aclopCast(const aclTensorDesc *srcDesc, const aclDataBuffer *srcBuffer, const aclTensorDesc *dstDesc, aclDataBuffer *dstBuffer, uint8_t truncate, aclrtStream stream)

Python Function

        
             ret = acl.op.cast(src_desc, src_buffer, dst_desc, dst_buffer, truncate, stream)

Parameter Description

Parameter	Description
src_desc	Int, pointer address of the input tensor description.
src_buffer	Int, input tensor, the aclDataBuffer pointer address created by calling acl.create_data_buffer.
dst_desc	Int, pointer address of the output tensor description.
dst_buffer	Int, output tensor, the aclDataBuffer pointer address created by calling acl.create_data_buffer.
truncate	Int, reserved.
stream	Int, stream where the operator is executed, stream address object.

Return Value Description

Return Value	Description
ret	Int, error code: 0 on success; else, failure.
