Deeplab v2 调试全过程（Ubuntu 16.04+cuda8.0）

本人刚接触深度学习与caffe，经过几天的填坑，终于把Deeplabv2的 run_pascal.sh与run_densecrf.sh成功运行，现将调试过程整理如下：

  • 一、安装必要的依赖库
    安装 matio:
    安装方法1：
    sudo apt-get install libmatio-dev
    安装方法2：
    下载matio(https://sourceforge.net/projects/matio/files/matio/1.5.2/)
    tar zxf matio-1.5.2.tar.gz
    cd matio-1.5.2
    ./configure
    make
    make check
    make install
    sudo ldconfig
    安装 wget
    sudo pip install wget 出错
    按照下面的命令成功：
    pip install –upgrade pip –user
    pip install –upgrade setuptools –user
    sudo pip install wget

  • 二、下载Deeplabv2并编译
    1、下载代码：
    git clone https://github.com/xmojiao/deeplab_v2.git
    （试过许多Deeplab代码，这个最容易编译成功，所以我用的是这个代码编译的）。
    2、对 caffe 进行编译：
    修改deeplab_v2/deeplab-public-ver2/路径下的 Makefile.config.example文件，重命名为Makefile.config，接着修改这个文件中的内容，将第四行的 “# USE_CUDNN := 1”的 # 去掉。如果需要，因为我用的pycaffe编译，所以不需要修改python的路径，保存退出。
    下面为编译 caffe的命令：
    cd ~/Desktop/deeplab_v2/deeplab-public-ver2
    make all -j16
    这时会出现下面的错误1：
    src/caffe/net.cpp:8:18: fatal error: hdf5.h: No such file or directory
    compilation terminated.
    解决办法: 修改两个make文件（Makefile.config，Makefile）
    Makefile.config：
    将
    INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include
    LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib
    修改为：
    INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial
    LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnumake
    Makefile：
    将
    LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_hl hdf5
    修改为：
    LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_serial_hl hdf5_serial matio
    重新编译：
    make all -j16
    这时会出现下面的错误2：
    ./include/caffe/common.cuh(9): error: function “atomicAdd(double *, double)” has already been defined
    **解决方法：打开./include/caffe/common.cuh文件，在atomicAdd前添加宏判断即可。
    下面为修改后文件：**

   // Copyright 2014 George Papandreou    #ifndef CAFFE_COMMON_CUH_    #define CAFFE_COMMON_CUH_    #include <cuda.h>    // CUDA: atomicAdd is not defined for doubles    #if !defined(__CUDA_ARCH__) || __CUDA_ARCH__ >= 600     #else    static __inline__ __device__ double atomicAdd(double *address, double val) {      unsigned long long int* address_as_ull = (unsigned long long int*)address;      unsigned long long int old = *address_as_ull, assumed;      if (val==0.0)        return __longlong_as_double(old);      do {        assumed = old;        old = atomicCAS(address_as_ull, assumed, __double_as_longlong(val +__longlong_as_double(assumed)));      } while (assumed != old);      return __longlong_as_double(old);    }    #endif    #endif
继续编译： make all -j16

这时会出现下面的错误3：:.build_release/lib/libcaffe.so:undefined
reference to `cudnnConvolutionBackwardFilter_v3’
解决方法：
将BVLC(https://github.com/BVLC/caffe)中的下列文件copy 到相应的文件夹：
./include/caffe/util/cudnn.hpp
./include/caffe/layers/cudnn_conv_layer.hpp
./include/caffe/layers/cudnn_relu_layer.hpp
./include/caffe/layers/cudnn_sigmoid_layer.hpp
./include/caffe/layers/cudnn_tanh_layer.hpp
./src/caffe/layers/cudnn_conv_layer.cpp
./src/caffe/layers/cudnn_conv_layer.cu
./src/caffe/layers/cudnn_relu_layer.cpp
./src/caffe/layers/cudnn_relu_layer.cu
./src/caffe/layers/cudnn_sigmoid_layer.cpp
./src/caffe/layers/cudnn_sigmoid_layer.cu
./src/caffe/layers/cudnn_tanh_layer.cpp
./src/caffe/layers/cudnn_tanh_layer.cu

make clean
make all -j16
make pycaffe -j16
编译成功。
这里写图片描述

2、对 run_pascal.sh 进行调试：
（1）首先准备好数据
（我是按照这篇博客准备的数据： http://blog.csdn.net/Xmo_jiao/article/details/77897109）
cd ~/Desktop
mkdir -p my_dataset
# augmented PASCAL VOC
cd my_dataset/
wget http://www.eecs.berkeley.edu/Research/Projects/CS/vision/grouping/semantic_contours/benchmark.tgz # 1.3 GB
tar -zxvf benchmark.tgz
mv benchmark_RELEASE VOC_aug

# original PASCAL VOC 2012
wget http://host.robots.ox.ac.uk/pascal/VOC/voc2012/VOCtrainval_11-May-2012.tar # 2 GB
tar -xvf VOCtrainval_11-May-2012.tar
mv VOCdevkit/VOC2012 VOC2012_orig && rm -r VOCdevkit

这里写图片描述

(2)数据转换

因为pascal voc2012增强数据集的label是mat格式的文件，要把mat格式的label转为png格式的图片.
~/Desktop/my_dataset/VOC_aug/dataset
mkdir cls_png
cd ~/Desktop/deeplab_v2/voc2012/
./mat2png.py ~/Desktop/my_dataset/VOC_aug/dataset/cls /Desktop/my_dataset/VOC_aug/dataset/cls_png

因为pascal voc2012原始数据集的label为三通道RGB图像，但是caffe最后一层softmax loss
层只能识别一通道的label,所以此处我们需要对原始数据集的label进行降维
cd ~/Desktop/my_dataset/VOC2012_orig
mkdir SegmentationClass_1D
cd ~/Desktop/deeplab_v2/voc2012/
./convert_labels.py ~/Desktop/my_dataset/VOC2012_orig/SegmentationClass/ ~/Desktop/my_dataset
/VOC2012_orig/ImageSets/Segmentation/trainval.txt ~/Desktop/my_dataset/VOC2012_orig/Segmentat
ionClass_1D/

（3）数据融合

此时已经处理好好pascal voc2012 增强数据集和pascal voc2012的原始数据集，为了便于train.txt等文件的调用，将两个文件夹数据合并到同一个文件中.现有文件目录如下：

这里写图片描述
这里写图片描述

现分别pascal voc2012增强数据集里的images和labels复制到增强数据集中，若重复则覆盖，合将并数据集的操作如下：
cp ~/Desktop/my_dataset/VOC2012_orig/SegmentationClass_1D/* ~/Desktop/my_dataset/VOC_aug/dataset/cls_png
cp ~/Desktop/my_dataset/VOC2012_orig/JPEGImages/* ~/Desktop/my_dataset/VOC_aug/dataset/img/

(4)文件名修改

对应train.txt文件的数据集文件名，修改文件名。
cd ~/Desktop/my_dataset/VOC_aug/dataset
mv ./img ./JPEGImages
那么我们这个阶段使用的数据已经整理完成

这里写图片描述

（5）修改并运行 run_pascal.sh
1）准备必要的文件
需要的文件从这里下载 deeplabv2 有两种模型（vgg，Res102），我用的vgg ，http://liangchiehchen.com/projects/DeepLab_Models.html
总共需要的文件如图所示：

这里写图片描述

下载的代码中 Desktop/deeplab_v2/voc2012/list 已经有了list文件，所以不用重新下载。
这里写图片描述
这里写图片描述

/Desktop/deeplab_v2/voc2012/config/deeplab_largeFOV中也有了相应的文件，所以也无需下载。

这里写图片描述

Desktop/deeplab_v2/voc2012/model/deeplab_largeFOV 里没有model，需要把下载好的model放入文件，如图所示：

这里写图片描述

至此，所有需要的文件全部完毕。

2）运行 train 和 test
进入/Desktop/deeplab_v2/voc2012，修改 run_pascal.sh 文件，主要是修改路径，我的修改后的文件如下：

  #!/bin/sh## MODIFY PATH for YOUR SETTINGROOT_DIR=/home/mmt/Desktop/my_datasetCAFFE_DIR=/home/mmt/Desktop/deeplab_v2/deeplab-public-ver2CAFFE_BIN=${CAFFE_DIR}/build/tools/caffe.binEXP=.if [ "${EXP}" = "." ]; then    NUM_LABELS=21    DATA_ROOT=${ROOT_DIR}/VOC_aug/dataset/else    NUM_LABELS=0    echo "Wrong exp name"fi## Specify which model to train########### voc12 ################NET_ID=deeplab_largeFOV## Variables used for weakly or semi-supervisedly training#TRAIN_SET_SUFFIX=TRAIN_SET_SUFFIX=_aug#TRAIN_SET_STRONG=train#TRAIN_SET_STRONG=train200#TRAIN_SET_STRONG=train500#TRAIN_SET_STRONG=train1000#TRAIN_SET_STRONG=train750#TRAIN_SET_WEAK_LEN=5000DEV_ID=0####### Create dirsCONFIG_DIR=${EXP}/config/${NET_ID}MODEL_DIR=${EXP}/model/${NET_ID}mkdir -p ${MODEL_DIR}LOG_DIR=${EXP}/log/${NET_ID}mkdir -p ${LOG_DIR}export GLOG_log_dir=${LOG_DIR}## RunRUN_TRAIN=1   #1时trainRUN_TEST=0    #1时testRUN_TRAIN2=0RUN_TEST2=0## Training #1 (on train_aug)if [ ${RUN_TRAIN} -eq 1 ]; then    #    LIST_DIR=${EXP}/list    TRAIN_SET=train${TRAIN_SET_SUFFIX}    if [ -z ${TRAIN_SET_WEAK_LEN} ]; then                TRAIN_SET_WEAK=${TRAIN_SET}_diff_${TRAIN_SET_STRONG}                comm -3 ${LIST_DIR}/${TRAIN_SET}.txt ${LIST_DIR}/${TRAIN_SET_STRONG}.txt > ${LIST_DIR}/${TRAIN_SET_WEAK}.txt    else                TRAIN_SET_WEAK=${TRAIN_SET}_diff_${TRAIN_SET_STRONG}_head${TRAIN_SET_WEAK_LEN}                comm -3 ${LIST_DIR}/${TRAIN_SET}.txt ${LIST_DIR}/${TRAIN_SET_STRONG}.txt | head -n ${TRAIN_SET_WEAK_LEN} > ${LIST_DIR}/${TRAIN_SET_WEAK}.txt    fi    #    MODEL=${EXP}/model/${NET_ID}/init.caffemodel    #    echo Training net ${EXP}/${NET_ID}    for pname in train solver; do                sed "$(eval echo $(cat sub.sed))" \                        ${CONFIG_DIR}/${pname}.prototxt > ${CONFIG_DIR}/${pname}_${TRAIN_SET}.prototxt    done        CMD="${CAFFE_BIN} train \         --solver=${CONFIG_DIR}/solver_${TRAIN_SET}.prototxt \         --gpu=${DEV_ID}"        if [ -f ${MODEL} ]; then                CMD="${CMD} --weights=${MODEL}"        fi        echo Running ${CMD} && ${CMD}fi## Test #1 specification (on val or test)if [ ${RUN_TEST} -eq 1 ]; then    #    for TEST_SET in val; do                TEST_ITER=`cat ${EXP}/list/${TEST_SET}.txt | wc -l`                MODEL=${EXP}/model/${NET_ID}/test.caffemodel                if [ !

接下来运行代码：
Train：
~/Desktop/deeplab_v2/voc2012
sh ./run_pascal.sh
运行结果如下：

这里写图片描述

Test：
将相应变量改为1：
~/Desktop/deeplab_v2/voc2012
sh ./run_pascal.sh
运行结果如下：

这里写图片描述

因为结果保存的是mat文件，如果想转换成png的形式，运行：
cd ~/Desktop/deeplab_v2/voc2012
修改create_labels_21.py的路径，然后此目录运行：
python create_labels_21.py
因为训练一会，我就暂停了，所以test的结果不好，而且图像的分割后的尺寸变了，不知道什么原因，不过经过densecrf后会变回来。

这里写图片描述

（6）修改并运行 run_densecrf.sh
1）首先对densecrf进行编译。
cd ~/Desktop/deeplab_v2/deeplab-public-ver2/densecrf/
make
有许多warning，但是没出错，不用管。
2）数据整理
因为densecrf只识别ppm格式的图像，所以要转换格式。进入/Desktop/deeplab_v2/deeplab-public-ver2/densecrf/my_script，里面有自带的修改ppm 的MATLAB程序，修改路径，直接运行即可。
代码如下：

% save jpg images as bin file for cpp%is_server = 1;dataset = 'voc2012';  %'coco', 'voc2012'if is_server  if strcmp(dataset, 'voc2012')    img_folder  = '/home/mmt/Desktop/my_dataset/VOC_aug/dataset/JPEGImages'    save_folder = '/home/mmt/Desktop/my_dataset/VOC_aug/dataset/PPMImages';  elseif strcmp(dataset, 'coco')    img_folder  = '/rmt/data/coco/JPEGImages';    save_folder = '/rmt/data/coco/PPMImages';  endelse  img_folder = '../img';  save_folder = '../img_ppm';endif ~exist(save_folder, 'dir')    mkdir(save_folder);endimg_dir = dir(fullfile(img_folder, '*.jpg'));for i = 1 : numel(img_dir)    fprintf(1, 'processing %d (%d)...\n', i, numel(img_dir));    img = imread(fullfile(img_folder, img_dir(i).name));    img_fn = img_dir(i).name(1:end-4);    save_fn = fullfile(save_folder, [img_fn, '.ppm']);    imwrite(img, save_fn);   end

2）接下来，修改 run_densecrf.sh， 注意把 MODEL_NAME=deeplab_largeFOV修改了，原文件少了一个 p。

DATASET=voc2012  修改；SAVE_DIR=/home/mmt/Desktop/deeplab_v2/${DATASET}/res/${FEATURE_NAME}/${MODEL_NAME}/${TEST_SET} 修改；CRF_DIR=/home/mmt/Desktop/deeplab_v2/deeplab-public-ver2/densecrf  修改；if [ ${DATASET} == "voc2012" ]then    IMG_DIR_NAME=VOC_aug/dataset     修改；FEATURE_DIR=/home/mmt/Desktop/deeplab_v2/${DATASET}/${FEATURE_NAME}/${MODEL_NAME}/${TEST_SET}/${FEATURE_TYPE}  修改；同时把一些不需要的语句都注释掉，要不然容易出错，显示找不到文件。修改后的文件如下：#!/bin/bash ############################################ You can either use this script to generate the DenseCRF post-processed results# or use the densecrf_layer (wrapper) in Caffe###########################################DATASET=voc2012LOAD_MAT_FILE=1MODEL_NAME=deeplab_largeFOVTEST_SET=val           #val, test# the features  folder save the features computed via the model trained with the train set# the features2 folder save the features computed via the model trained with the trainval setFEATURE_NAME=features #features, features2FEATURE_TYPE=fc8# specify the parametersMAX_ITER=10Bi_W=4Bi_X_STD=49Bi_Y_STD=49Bi_R_STD=5Bi_G_STD=5 Bi_B_STD=5POS_W=3POS_X_STD=3POS_Y_STD=3######################################## MODIFY THE PATY FOR YOUR SETTING#######################################SAVE_DIR=/home/mmt/Desktop/deeplab_v2/${DATASET}/res/${FEATURE_NAME}/${MODEL_NAME}/${TEST_SET}/${FEATURE_TYPE}/post_densecrf_W${Bi_W}_XStd${Bi_X_STD}_RStd${Bi_R_STD}_PosW${POS_W}_PosXStd${POS_X_STD}echo "SAVE TO ${SAVE_DIR}"CRF_DIR=/home/mmt/Desktop/deeplab_v2/deeplab-public-ver2/densecrf#if [ ${DATASET} == "voc2012" ]#then    IMG_DIR_NAME=VOC_aug/dataset#elif [ ${DATASET} == "coco" ]#then #   IMG_DIR_NAME=coco#elif [ ${DATASET} == "voc10_part" ]#then  #  IMG_DIR_NAME=pascal/VOCdevkit/VOC2012#fi# NOTE THAT the densecrf code only loads ppm imagesIMG_DIR=/home/mmt/Desktop/my_dataset/${IMG_DIR_NAME}/PPMImages#if [ ${LOAD_MAT_FILE} == 1 ]#then    # the features are saved in .mat format    CRF_BIN=${CRF_DIR}/prog_refine_pascal_v4    FEATURE_DIR=/home/mmt/Desktop/deeplab_v2/${DATASET}/${FEATURE_NAME}/${MODEL_NAME}/${TEST_SET}/${FEATURE_TYPE}#else    # the features are saved in .bin format (has called SaveMatAsBin.m in the densecrf/my_script)   # CRF_BIN=${CRF_DIR}/prog_refine_pascal   # FEATURE_DIR=/home/mmt/Desktop/deeplab_v2/${DATASET}/${FEATURE_NAME}/${MODEL_NAME}/${TEST_SET}/${FEATURE_TYPE}/bin#fimkdir -p ${SAVE_DIR}# run the program${CRF_BIN} -id ${IMG_DIR} -fd ${FEATURE_DIR} -sd ${SAVE_DIR} -i ${MAX_ITER} -px ${POS_X_STD} -py ${POS_Y_STD} -pw ${POS_W} -bx ${Bi_X_STD} -by ${Bi_Y_STD} -br ${Bi_R_STD} -bg ${Bi_G_STD} -bb ${Bi_B_STD} -bw ${Bi_W}

进入文件路径，运行程序，结果如下图：
cd ~/Desktop/deeplab_v2/voc2012/
sh sh ./run_densecrf.sh

这里写图片描述

3）然后运行 /home/mmt/crf/deeplab-public-ver2/densecrf/my_script/GetDenseCRFResult.m把bin生成图片格式
注意修改文件路径（GetDenseCRFResult.m，SetupEnv在/deeplab_v2/deeplab-public-ver2/matlab/my_script中），
两个程序的代码如下：
