[BUG] test_add.py 跑graph 测试报错

[grybd]

背景信息

将test_add.py中的test_0dim_inplace_add(test_case) 打开check_graph=True ,再跑test_add.py报错，报错信息如下：

======================================================================
FAIL: test_0dim_inplace_add (__main__.TestAddModule)
----------------------------------------------------------------------
assert (
AssertionError: Check graph failed: graph result [[1.392592  1.2263045 1.4627435]
 [1.3013713 1.7706606 1.7302301]] not equals to eager result [[0.788282  0.6219945 0.8584335]
 [0.6970614 1.1663506 1.12592  ]].

合并lixiang 的#7276 分支(解决inplace op 跑graph 测试参数deepcopy的分支Fix_autotest_inplace_bug)再跑测试还是会报错，报错信息：

在oneflow下做了测试eager 和graph的结果是不对齐的

import oneflow as flow
import numpy as np 

a=flow.randn(2,3)
b=flow.randn(1,10)

x = flow.Tensor(a).to("cpu")
print("x :",x)
y = flow.Tensor(b).to("cpu")
print("y: ",y)

x_1 = x
x_2 = x
y_1 = y
y_2 = y

x_1 = flow.add(x_1,y_1.mean())
print("eager, 非inplace")
print("-------------------------------------")
print(x_1)

x_2 = flow.add(x_2,y_2.mean(),inplace=True)
print("eager, inplace")
print("-------------------------------------")
print(x_2)

def model(x,y):
    return flow.add(x,y.mean(),inplace=True)

class Graph(flow.nn.Graph):
    def __init__(self):
        super().__init__()
        self.m=model

    def build(self,x,y):
        out = self.m(x,y)
        return out

graph=Graph()
out_=graph(x,y.mean())

print("graph, inplace")
print("-------------------------------------")
print(out_)

输出结果：

        [-2.1822,  0.5900, -0.3539]], dtype=oneflow.float32)
