2 报错信息

2.1脚本信息

import mindspore as ms
import mindspore.ops as ops
import numpy as np

x1 = ms.Tensor(np.random.rand(2,3))
x2 = ms.Tensor(np.random.rand(3,4))
out = ops.mm(x1,x2)
print(out.shape)复制

2.2报错信息

3 根因分析

查看api 版本1.10.0

记得查询的时候一定要带版本号

从结果上看1.10版本是没有ops.mm的

再查询最新的API 2.2版本,是能查询到的

4 解决方案

既然没有mm就用ops.matmul来代替

import mindspore as ms  
import mindspore.ops as ops  
import numpy as np  
  
x1 = ms.Tensor(np.random.rand(2,3))  
x2 = ms.Tensor(np.random.rand(3,4))  
out = ops.matmul(x1,x2)  
print(out.shape)
