#### 问题现象描述

报错文本：

```
[ERROR] GE(24836,python3.7):2021-01-27-18:27:51.562.111 [../../../../../../graphengine/ge/engine_manager/dnnengine_manager.cc:266]25155 GetDNNEngineName: ErrorNo: 1343242282(assign engine failed) GetDNNEngineName:Op type SigmoidCrossEntropyWithLogitsV2 of ops kernel AIcoreEngine is unsupported, reason:Op SigmoidCrossEntropyWithLogitsV2 not supported reason: The type of this op is not found in op store, check whether the op store has this type of op. Op store name is tbe-custom.
The dtype, format or shape of input in op desc is not supported in op store, check the dtype, format or shape of input between the op store and the graph. Op store name is tbe-builtin.
```

#### 原因分析

SigmoidCrossEntropyWithLogitsV2算子输入了不支持的数据类型，可能是输入int64类型导致的错误。

#### 解决措施

检查对应Python代码中输入的数据类型并修改。
