Faster RCNN CPU安装记录

参考博客：Faster-RCNN+ZF用自己的数据集训练模型（Python版本）

目前执行了2中的(1)(2)，由于在make时遇到了错误（无GPU的原因），搜索了下面的博客进行安装

遇到的问题与相关不同：

1、cython编译出错

python setup.py build_ext --inplace
Traceback (most recent call last):
  File "setup.py", line 56, in <module>
    CUDA = locate_cuda()
  File "setup.py", line 44, in locate_cuda
    raise EnvironmentError('The nvcc binary could not be '
EnvironmentError: The nvcc binary could not be located in your $PATH. Either add it to your path, or set $CUDAHOME
Makefile:2: recipe for target 'all' failed
make: *** [all] Error 1

解决方案：

1）注释掉setup.py中的CUDA = locate_cuda()

报错：

python setup.py build_ext --inplace
Traceback (most recent call last):
  File "setup.py", line 125, in <module>
    library_dirs=[CUDA['lib64']],
NameError: name 'CUDA' is not defined
Makefile:2: recipe for target 'all' failed
make: *** [all] Error 1

2）寻找setup中所有与gpu有关的代码注释掉

#    Extension('nms.gpu_nms',
#        ['nms/nms_kernel.cu', 'nms/gpu_nms.pyx'],
#        library_dirs=[CUDA['lib64']],
#        libraries=['cudart'],
#        language='c++',
#        runtime_library_dirs=[CUDA['lib64']],
#        # this syntax is specific to this build system
#        # we're only going to use certain compiler args with nvcc and not with
#        # gcc the implementation of this trick is in customize_compiler() below
#        extra_compile_args={'gcc': ["-Wno-unused-function"],
#                            'nvcc': ['-arch=sm_35',
#                                     '--ptxas-options=-v',
#                                     '-c',
#                                     '--compiler-options',
#                                     "'-fPIC'"]},
#        include_dirs = [numpy_include, CUDA['include']]
#    ),

提示：（这应该是成功了吧）

rm -rf build

2、Makefile.config 中的 CPU_ONLY=1的注释去掉

# CPU-only switch (uncomment to build without GPU support).
CPU_ONLY := 1

参考博客：Faster R-CNN CPU环境搭建

遇到的问题与相关不同

1、caffe、opencv之前安装完成，未执行1; caffe-fast-rcnn上一步make完成，未执行2

2、运行./fetch_faster_rcnn_models.sh 时连接超时

解决：1）使用第一篇博客在评论中提供的下载地址下载py-faster-rcnn faster_rcnn_models.tgz。网址点击Download下载下来一个种子，使用百度云或者迅雷下载数据:

等待下载之余运行了一下demo.py出现了以下错误：缺少matplotlib，使用

sudo apt-get install python-matplotlib#安装matplotlib

Traceback (most recent call last):
  File "./demo.py", line 21, in <module>
    import matplotlib.pyplot as plt
  File "/home/lys/.local/lib/python2.7/site-packages/matplotlib/pyplot.py", line 115, in <module>
    _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup()
  File "/home/lys/.local/lib/python2.7/site-packages/matplotlib/backends/__init__.py", line 32, in pylab_setup
    globals(),locals(),[backend_name],0)

    mod = mod._resolve()

    return _import_module(self.mod)
  File "/home/lys/.local/lib/python2.7/site-packages/six.py", line 82, in _import_module
    __import__(name)

    raise ImportError, str(msg) + ', please install the python-tk package'
ImportError: No module named _tkinter, please install the python-tk package

安装之后果然就是model还没下载的错误啦，安心等着下载完。。。。。。希望不会再出错，祈祷

下载完成后将压缩包解压到.../py-faster-rcnn/data/faster_rcnn_models，在.../py-faster-rcnn/tools/下运行 python demo.py --cpu

出现如下错误：

Traceback (most recent call last):
  File "/home/lys/py-faster-rcnn/tools/../lib/rpn/proposal_layer.py", line 10, in <module>
    import yaml
ImportError: No module named yaml
Traceback (most recent call last):
  File "demo.py", line 135, in <module>
    net = caffe.Net(prototxt, caffemodel, caffe.TEST)
SystemError: NULL result without error in PyObject_Call

使用sudo apt-get install python-yaml进行安装yaml（YAML是一种直观的能够被电脑识别的的数据序列化格式，容易被人类阅读，并且容易和脚本语言交互。YAML类似于XML，但是语法比XML简单得多，对于转化成数组或可以hash的数据时是很简单有效的.yaml在python中的使用 )

再次执行demo.py，运行成功。
