caffe跑densenet的错误:Message type "caffe.PoolingParameter" has no field named "ceil_mode".【转自CSDN】

最近看了densenet这篇论文,论文做者给了基于caffe的源码,本身在电脑上跑了下,可是出现了Message type “caffe.PoolingParameter” has no field named “ceil_mode”.的错误,现将解决办法记载以下。主要是参考
https://github.com/BVLC/caffe/pull/3057/files)。错误缘由:因为caffe的版本的缘由,现用的caffe的源码中的pooling层没有ceil_mode
这个函数,所以解决办法也是在如今的源码中网pooling层中添加这个参数以及相关的代码,并从新编译caffe便可。git

一、修改pooling_layer.hpp文件PoolingLayer类

在pooling_layer.hpp中往PoolingLayer类中添加ceil_mode_这个参数,修改以下:github

int height_, width_; int pooled_height_, pooled_width_; bool global_pooling_; bool ceil_mode_; //添加的类成员变量 Blob<Dtype> rand_idx_; Blob<int> max_idx_;

二、修改pooling_layer.cpp文件中相关参数

主要涉及到LayerSetUp函数和Reshape函数。LayerSetUp函数修改以下:markdown

|| (!pool_param.has_stride_h() && !pool_param.has_stride_w())) << "Stride is stride OR stride_h and stride_w are required."; global_pooling_ = pool_param.global_pooling(); ceil_mode_ = pool_param.ceil_mode(); //添加的代码,主要做用是从参数文件中获取ceil_mode_的参数数值。 if (global_pooling_) { kernel_h_ = bottom[0]->height(); kernel_w_ = bottom[0]->width(); if (pad_h_ != 0 || pad_w_ != 0) { CHECK(this->layer_param_.pooling_param().pool() == PoolingParameter_PoolMethod_AVE || this->layer_param_.pooling_param().pool() == PoolingParameter_PoolMethod_MAX) << "Padding implemented only for average and max pooling."; CHECK_LT(pad_h_, kernel_h_); CHECK_LT(pad_w_, kernel_w_); .......

Reshape函数修改以下:ide

void PoolingLayer<Dtype>::Reshape(const vector<Blob<Dtype>*>& bottom, const vector<Blob<Dtype>*>& top) { CHECK_EQ(4, bottom[0]->num_axes()) << "Input must have 4 axes, " << "corresponding to (num, channels, height, width)"; channels_ = bottom[0]->channels(); height_ = bottom[0]->height(); width_ = bottom[0]->width(); if (global_pooling_) { kernel_h_ = bottom[0]->height(); kernel_w_ = bottom[0]->width(); } - pooled_height_ = static_cast<int>(ceil(static_cast<float>( - height_ + 2 * pad_h_ - kernel_h_) / stride_h_)) + 1; - pooled_width_ = static_cast<int>(ceil(static_cast<float>( - width_ + 2 * pad_w_ - kernel_w_) / stride_w_)) + 1; + // Specify the structure by ceil or floor mode + + // 添加的代码----------------------------------- + if (ceil_mode_) { + pooled_height_ = static_cast<int>(ceil(static_cast<float>( + height_ + 2 * pad_h_ - kernel_h_) / stride_h_)) + 1; + pooled_width_ = static_cast<int>(ceil(static_cast<float>( + width_ + 2 * pad_w_ - kernel_w_) / stride_w_)) + 1; + } else { + pooled_height_ = static_cast<int>(floor(static_cast<float>( + height_ + 2 * pad_h_ - kernel_h_) / stride_h_)) + 1; + pooled_width_ = static_cast<int>(floor(static_cast<float>( + width_ + 2 * pad_w_ - kernel_w_) / stride_w_)) + 1; + } + // ------------------------------------------------------ + if (pad_h_ || pad_w_) { // If we have padding, ensure that the last pooling starts strictly // inside the image (instead of at the padding); otherwise clip the last.

三、修改caffe.proto文件中PoolingParameter的定义

由于添加了pooling层的参数,所以须要修改caffe.proto文件中PoolingParameter中的定义,须要增长参数的声明。函数

// If global_pooling then it will pool over the size of the bottom by doing // kernel_h = bottom->height and kernel_w = bottom->width optional bool global_pooling = 12 [default = false]; + // Specify floor/ceil mode + optional bool ceil_mode = 13 [default = true];// 为pooling层添加参数,这样能够在net.prototxt文件中为pooling层设置该参数,注意后面须要给其设置一个ID,同时设置一个默认值。 }
四、从新编译caffe

返回到caffe的根目录,使用make指令,便可。ui

make -j32 // 这里j后面的数字与电脑配置有关系,能够加速编译 

注意:这个流程也是通常修改caffe的层的通常流程:一、主要修改相应层的hpp文件和cpp文件;二、若是有参数的添加或者减小,还须要修改caffe.proto文件对应层的参数便可(注意设置正确的ID以及默认值default);三、从新编译caffe
