如何在Ubuntu18.04上安装caffe+darknet2caffe环境

Ubuntu的安装请参考《如何快速安装Ubuntu18.04》

samba服务的配置请参考《如何在Ubuntu配置Samba服务》

前提：由于在安装darknet2caffe环境的时候需要下载并安装torch

• 在执行 pip3 install torch的时候，总是会被killed(已杀死)，所以这里需要对Ubuntu的运行内存做一下配置。
  确保你的Ubuntu是在关机状态，点击内存，将内存调至4GB(至少)，然后再给Ubuntu开机，此时Ubuntu的运行内存就是4GB了。

一、在Ubuntu18.04上安装caffe环境

1、分步执行下面的命令，对Ubuntu里面的软件进行更新

sudo apt-get update
sudo apt-get upgrade

2、分步执行下面的命令，安装所需的依赖软件。

sudo apt-get install  -y libopencv-dev
sudo apt-get install -y build-essential cmake git pkg-config
sudo apt-get install -y libprotobuf-dev libleveldb-dev libsnappy-dev libhdf5-serial-dev protobuf-compiler
sudo apt-get install -y liblapack-dev
sudo apt-get install -y libatlas-base-dev 
sudo apt-get install -y --no-install-recommends libboost-all-dev
sudo apt-get install -y libgflags-dev libgoogle-glog-dev liblmdb-dev
sudo apt-get install -y python-numpy python-scipy
sudo apt-get install -y python3-pip
sudo apt-get install -y python3-numpy python3-scipy

3、执行下面的命令，下载caffe开源软件

git clone https://github.com/BVLC/caffe.git

4、进入caffe/python/目录下，执行下面的命令，下载依赖的软件

cd caffe/python/
for req in $(cat requirements.txt); do pip3 install $req; done

5、进入caffe目录下，执行下面的命令，将 Makefile.config.example 文件复制一份并更名为 Makefile.config

cp Makefile.config.example  Makefile.config

6、接下来是修改Makefile.config里面的配置,使用vim命令打开Makefile.config。

vim Makefile.config

• ① 将CPU_ONLY前面的注释去掉。

将 
# CPU_ONLY := 1
改为
CPU_ONLY := 1

• ② 将OPENCV_VERSION前面的注释去掉

将
# OPENCV_VERSION := 3
改为
OPENCV_VERSION := 3

• ③ 因为我们Ubuntu的环境是python，所以请把PYTHON_INCLUDE = python2.7这个配置前面加上注释，且把PYTHON_INCLUDE=python3.5的注释打开，把所有的3.5都改成3.6，具体修改如下
  
• ④ 将WITH_PYTHON_LAYER := 1前面的注释去掉

将 
# WITH_PYTHON_LAYER := 1
改为
WITH_PYTHON_LAYER := 1

• ⑤ 修改INCLUDE_DIRS和LIBRARY_DIRS

将 
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib
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-gnu /usr/lib/x86_64-linux-gnu/hdf5/serial

修改后的文件如下所示：

## Refer to http://caffe.berkeleyvision.org/installation.html

# Custom (MKL/ATLAS/OpenBLAS) include and lib directories.
# Leave commented to accept the defaults for your choice of BLAS
# (which should work)!

# PYTHON_INCLUDE := $(ANACONDA_HOME)/include \
		# $(ANACONDA_HOME)/include/python2.7 \
		# $(ANACONDA_HOME)/lib/python2.7/site-packages/numpy/core/include

# Uncomment to use Python 3 (default is Python 2)
PYTHON_LIBRARIES := boost_python3 python3.6m
PYTHON_INCLUDE := /usr/include/python3.6m \
                 /usr/lib/python3.6/dist-packages/numpy/core/include

# We need to be able to find libpythonX.X.so or .dylib.
PYTHON_LIB := /usr/lib
# PYTHON_LIB := $(ANACONDA_HOME)/lib

# Homebrew installs numpy in a non standard path (keg only)
# PYTHON_INCLUDE += $(dir $(shell python -c 'import numpy.core; print(numpy.core.__file__)'))/include
# PYTHON_LIB += $(shell brew --prefix numpy)/lib

# Uncomment to support layers written in Python (will link against Python libs)
WITH_PYTHON_LAYER := 1

# Whatever else you find you need goes here.
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-gnu /usr/lib/x86_64-linux-gnu/hdf5/serial

Q ?= @

7、修改Makefile文件里面的一些配置，使用vim 打开Makefile，进行修改。

vim Makefile

• ① 修改DYNAMIC_VERSION_REVISION的值

将
DYNAMIC_VERSION_REVISION 	:= 0
改为
DYNAMIC_VERSION_REVISION 	:= 0-rc3

• ② 修改 LIBRARIES 的值。

将
LIBRARIES += glog gflags protobuf boost_system boost_filesystem m
改为
LIBRARIES += glog gflags protobuf boost_system boost_filesystem boost_regex m hdf5_hl hdf5

将
LIBRARIES += opencv_imgcodecs
改为
LIBRARIES += opencv_imgcodecs opencv_videoio

• ③ 将# NCCL acceleration configuration下面的四行注释掉

将
# NCCL acceleration configuration
ifeq ($(USE_NCCL), 1)
	LIBRARIES += nccl
	COMMON_FLAGS += -DUSE_NCCL
endif
改为
# NCCL acceleration configuration
# ifeq ($(USE_NCCL), 1)
#	LIBRARIES += nccl
#	COMMON_FLAGS += -DUSE_NCCL
# endif

8、在caffe目录下，分步执行下面的命令，来编译caffe。

make -j4
make pycaffe

9、执行下面的命令，将caffe的python路径设置为环境变量，并更新环境变量。

执行下面的命令，打开.bashrc

sudo vim ~/.bashrc 

在文件的末尾加上下面的语句

export PYTHONPATH=/home/hispark/code/caffe/python:$PYTHONPATH

再执行下面的命令，更新环境变量

source ~/.bashrc

10、测试caffe环境是否OK，在Ubuntu的任意目录下，执行 python3，当出现”>>>”的提示符后，再输入import caffe，如果没有任何报错信息，说明caffe环境已经搭建成功了。

python3
import caffe

二、执行下面的步骤，安装darknet2caffe环境

1、分步执行下面的命令，安装编译darknet2caffe时需要的torch环境

pip3 install torch==1.4.0  --no-cache-dir
pip3 install torchvision==0.5.0 --no-cache-dir

2、执行下面的命令，下载darknet2caffe的代码到Ubuntu。

git clone https://github.com/ChenYingpeng/darknet2caffe

3、由于python的本地版本是python3.6，开源代码为 python2.X，因此需要对代码语法做适当调整

• ① 将 darknet2caffe.py 中的所有的 if block.has_key('name'): 替换成 if 'name' in block:

• ② 再将caffe_root修改为caffe的实际的绝对路径，如：/home/hispark/code/caffe/

将
caffe_root='/home/chen/caffe/'
改为
caffe_root='/home/hispark/code/caffe/'  # /home/hispark/code/caffe/是你caffe的路径

• ③ 将prototxt.py 安装下图方式进行修改
  
  修改后的protxt.py如下所示

from collections import OrderedDict
try:
    import caffe.proto.caffe_pb2 as caffe_pb2
except:
    try:
        import caffe_pb2
    except:
        print('caffe_pb2.py not found. Try:')
        print('  protoc caffe.proto --python_out=.')
        exit()

def parse_caffemodel(caffemodel):
    model = caffe_pb2.NetParameter()
    print('Loading caffemodel: ', caffemodel)
    with open(caffemodel, 'rb') as fp:

            if ltype == 0: # key: value
                #print line
                line = line.split('#')[0]
                key, value = line.split(':')
                key = key.strip()
                value = value.strip().strip('"')
                if block.has_key(key):
                    if type(block[key]) == list:
                        block[key].append(value)
                    else:
                        block[key] = [block[key], value]

                block[key] = sub_block
            line = fp.readline().strip()
            line = line.split('#')[0]
        return block

    fp = open(protofile, 'r')
    props = OrderedDict()
    layers = []
    line = fp.readline()
    while line != '':
        line = line.strip().split('#')[0]
        if line == '':
            line = fp.readline()
            continue
        ltype = line_type(line)

               if type(props[key]) == list:
                   props[key].append(value)
               else:
                   props[key] = [props[key], value]
            else:
                props[key] = value
        elif ltype == 1: # blockname {
    
    
            key = line.split('{')[0].strip()
            if key == 'layer':
                layer = parse_block(fp)
                layers.append(layer)
            else:
                props[key] = parse_block(fp)

def is_number(s):
    try:
        float(s)
        return True

        for key,value in block_info.items():
            if type(value) == OrderedDict:
                print_block(value, key, indent+4)
            elif type(value) == list:
                for v in value:
                    print('%s    %s: %s' % (blanks, key, format_value(v)))
            else:

    fp = open(protofile, 'w')
    # whether add double quote
    def format_value(value):
        #str = u'%s' % value

    def print_block(block_info, prefix, indent):
        blanks = ''.join([' ']*indent)
        print('%s%s {' % (blanks, prefix), end="\n", file=fp)
        for key,value in block_info.items():
            if type(value) == OrderedDict:
                print_block(value, key, indent+4)
            elif type(value) == list:
                for v in value:
                    print('%s    %s: %s' % (blanks, key, format_value(v)), end="\n", file=fp)
            else:
                if key[0:6] == 'biases':
                    key = 'biases'
                print('%s    %s: %s' % (blanks, key, format_value(value)), end="\n", file=fp)
        print('%s}' % blanks, end="\n", file=fp)
        
    props = net_info['props']
    layers = net_info['layers']
    print('name: \"%s\"' % props['name'], end="\n", file=fp)

    fp.close()


if __name__ == '__main__':
    import sys
    if len(sys.argv) != 2:
        print('Usage: python prototxt.py model.prototxt')
        exit()

    net_info = parse_prototxt(sys.argv[1])
    print_prototxt(net_info)
    save_prototxt(net_info, 'tmp.prototxt')
    

4、进入darknet2caffe目录，执行下面的命令，将三个文件拷贝到caffe目录下

cp caffe_layers/upsample_layer/upsample_layer.hpp  ../caffe/include/caffe/layers/
cp caffe_layers/upsample_layer/upsample_layer.c*  ../caffe/src/caffe/layers/

5、进入caffe的 src/caffe/proto/目录下，修改caffe.proto文件

cd ../caffe/src/caffe/proto/

在 message LayerParameter {}中新增 optional UpsampleParameter upsample_param = 150;

在caffe.proto最后添加UpsampleParameter参数，如下图所示：

 message UpsampleParameter {
    
    
         optional int32 scale = 1 [default = 1];
}

6、在caffe目录下，执行下面的命令，重新编译caffe环境。

make clean
make -j4
make pycaffe

到此，caffe和darknet2caffe的环境就在Ubuntu中安装好了。
