Because the using in a header file might break existing namespace hierarchy if we include that header file (https://google.github.io/styleguide/cppguide.html#Namespaces), usually we don't do that.

You specify indices type to int16 in https://github.com/sweetsky0901/Paddle/blob/27cf7f3376e2005522dbba8c964cb2e449b46380/python/paddle/v2/fluid/tests/test_unpool_op.py#L56 so, there must be wrong using const T * indices_data = indices.data<T>(); here, also, the paddle does not support int16 currently. So, you must specify int32 when test, and use const int * indices_data = indices.data<int>(); or add a new parameter type to the template, like here

done
系统默认对输入类型做了检查，必须一样，如果不一样，需要重写
protected:
framework::OpKernelType GetKernelType(
const framework::ExecutionContext& ctx) const override {
return framework::OpKernelType(
framework::ToDataType(ctx.Inputframework::Tensor("X")->type()),
ctx.device_context());
}
之前为了逃避这个检查，用float传递的index，然后到具体计算再强转的。

不是这样的
在注册Op的时候一般注册两个(double/float)，那么在op运行的时候到底是用哪个呢（double的还是float），这时候需要调用GetKernelType函数来判断，如果X是float，那就调float的Op，如果是double，那就调double的Op

请问这些有文档吗？

这个可以写在循环外面，将indices转为EigenMatrix或者EigenVector，之后调用maximum方法返回indices中最大元素，然后判断是否越界。
CUDA实现也可以这样做，避免在cuda kernel里面做越界检测。

调用maximum实际上又多了很多次比较，不太赞成这样的写法

感觉命名有点随意。

int in_c_stride = input_height * input_width; int in_n_stride = in_c_stride * channels; int out_c_stride = output_height * output_width; int out_n_stride = out_c_stride * channels;

数据是NCHW，这里就用了n_stride, c_stride，其他更好的命名也可以。但bsize, csize等觉得有点随意。

请安装格式检查工具！！！( 上个PR就说过)，这里的格式不符合Python格式。
= 前后有空格。

另外，python里不要大小写混合，这个python文件里好几处，请一并修改。

我已经装了这个工具了！！！！！但是就是没检查出来。

这里不用自己写max-pooling的forward，可以调用python/paddle/v2/fluid/tests/test_pool_max_op.py里的函数max_pool2D_forward_naive即可。

那单测文件不是互相依赖了吗？
