Compares
产品支持情况
功能说明
逐元素比较一个tensor中的元素和另一个Scalar的大小,如果比较后的结果为真,则输出结果的对应比特位为1,否则为0。
支持多种比较模式:
-
LT:小于(less than)
-
GT:大于(greater than)
-
GE:大于或等于(greater than or equal to)
-
EQ:等于(equal to)
-
NE:不等于(not equal to)
-
LE:小于或等于(less than or equal to)

类型为LocalTensor,支持的TPosition为VECIN/VECCALC/VECOUT。 dst用于存储比较结果,将dst中uint8_t类型的数据按照bit位展开,由左至右依次表征对应位置的src0和src1的比较结果,如果比较后的结果为真,则对应比特位为1,否则为0。 Ascend 950PR/Ascend 950DT,支持的数据类型为:uint8_t Atlas A3 训练系列产品/Atlas A3 推理系列产品,支持的数据类型为:uint8_t |

约束说明
-
操作数地址对齐要求请参见通用地址对齐约束。
-
dst按照小端顺序排序成二进制结果,对应src中相应位置的数据比较结果。
-
使用tensor前n个数据参与计算的接口,设置count时,需要保证count个元素所占空间256字节对齐。
-
针对Ascend 950PR/Ascend 950DT,int8_t/uint8_t/uint64_t/int64_t/double数据类型仅支持tensor前n个数据计算接口,double只支持CMPMODE::EQ。
调用示例
本样例中,源操作数src0Local存储了256个float类型的数据。样例实现的功能为,对src0Local中的元素和src1Local.GetValue(0)中的数据进行比较,如果src0Local中的元素小于src1Local.GetValue(0)中的元素,dstLocal结果中对应的比特位置1;反之,则置0。dst结果使用uint8_t类型数据存储。
