SSCNet环境搭建

自己留着，省着忘了
配置Semantic Scene Completion from a Single Depth Image http://sscnet.cs.princeton.edu/

硬件：GPU Quadro M6000 24G

最开始配置了caffe+CUDA8.0+cuDNN6.0+Anaconda2+python2.7
http://www.cnblogs.com/zhbzz2007/p/5499180.html
http://blog.csdn.net/u012604811/article/details/53791222

install anaconda2
http://blog.csdn.net/c406495762/article/details/65449495?locationNum=2&fps=1

Matlab配置
http://blog.csdn.net/lcx543576178/article/details/51376008

然后发现cuDNN版本过新，会报一些参数过少的错误，cuDNN版本改成了“cudnn-8.0-linux-x64-v5.1.tgz”

然后开始了无知的爬坑之旅……
开始不了解，以为自己配置好了cafee，SSCNet给的caffe3d_suncg就不需要管它了……
结果
WARNING: Logging before InitGoogleLogging() is written to STDERR

发现问题是，可能并不需要自己编译caffe，而是直接编译作者给的caffe_code即可。
开始想把作者对层的定义和参数复制到源生caffe中，后来放弃。

第二个坑出现了，死活编译不过，错误如下：

In file included from /usr/include/c++/4.8/future:35:0, from /home/mobilear/sscnet/caffe_code/caffe3d_suncg/include/caffe/layers/suncg_data_layer.hpp:4, from /home/mobilear/sscnet/caffe_code/caffe3d_suncg/src/caffe/layers/suncg_data_layer.cu:5: /usr/include/c++/4.8/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard.

然后我在CMakeList.txt中加入

list(APPEND CUDA_NVCC_FLAGS "-arch=sm_20;-std=c++11;-O2;-DVERBOSE") SET(CUDA_PROPAGATE_HOST_FLAGS OFF)

接着报错：

百思不得其解

最后发现，需要在caffe的源CMakeList.txt中改即可，而不是在src中的CMakeList.txt
相对路径： sscnet/caffe_code/caffe3d_suncg/CMakeList.txt
位置在include(cmake/Dependencies.cmake)后面即可，改后的CMakeList.txt为：

然后报错：

把环境变量路径放到 ~/.bashrc文件中,打开文件
sudo vim ~/.bashrc
在文件下方写入
export PYTHONPATH=~/caffe/python:$PYTHONPATH
上述语句中 “～” 号表示caffe 所在的根目录。

再次出错：
ImportError: No module named google.protobuf.internal
我装的是anaconda2, 解决方法是在其中安装protobuf最新版本
sudo chmod 777 -R anaconda2
conda install protobuf

接下来准备使用自己的RGB-D数据来用网络跑下结果，我看github中有人问这个问题，感觉又会是一个坑=。=期待早出。
