takuya-takeuchi opened a new issue #9417: [cpp-package] inception_bn.cpp is wrong
URL: https://github.com/apache/incubator-mxnet/issues/9417
 
 
   ## Description
   Sample code is wrong. In InceptionFactoryB function, pooling variable is created by passing wrong arguments.
   
   ## Environment info (Required)
   Windows 7/10
   
   ## Build info (Required if built from source)
   
   Compiler (gcc/clang/mingw/visual studio): Visual Studio 2015
   
   MXNet commit hash: #c3d6cf09007dc11e1a5e2227075422911aa2eb3e
   
   ## Error Message:
   ```

   ```
   
   ## What have you tried to solve it?
   
   1. Change code
   ```
     Symbol pooling = Pooling("max_pool_" + name + "_pool", data,
                              Shape(3, 3), PoolingPoolType::kMax,
                              false, false, PoolingPoolingConvention::kValid, Shape(2, 2));
   ```
   to
   ```
     Symbol pooling = Pooling("max_pool_" + name + "_pool", data,
                              Shape(3, 3), PoolingPoolType::kMax,
                              false, false, PoolingPoolingConvention::kValid, Shape(2, 2), Shape(1, 1));
   ```
   
   2. Op.h provides default value for pad param as Shape(1, 1)
