一個簡單操作解決protobuf版本問題，復制粘貼你會吧

這個方法雖然簡單，但是我們有完美的利用anaconda的解決方案，能夠解決服務器上大家版本沖突，你想要幾個環境就可以建立幾個完全不沖突的環境，算是一本萬利，教程在http://www.cnblogs.com/SweetBeens/p/8650460.html，推薦用這種方法。當然docker更好一些，但是老代碼是沒有docker文件的。
從頭說起：

如何看你的需要安裝的版本呢，上圖：

注意看我的文件的路徑，這就是caffe官網上的那句命令行出處：

for req in $(cat requirements.txt); do pip install $req; done

鑒於我用的是segnet作者自己改的python版本的caffe，所以這是我的目錄，你可以窮搜，然后自己挑一個看看需要安裝什么。按理說照着我這個txt，不論我什么版本的都該好使，但是沒准我的txt找的不對，或者protobuf不向后兼容了，或者caffe找的anaconda的protobuf，版本有問題，總之我越來越想看有沒有caffe配置更詳細的官方原文doc，或者我應該看看linux from scrach。這種盲人摸象式解決問題損失了很多樂趣。

我現在開始折騰我們實驗室的服務器，里面的protobuf版本比較高，所以我要用2.6.1的，我首先用下面連接的方法安裝了2.6.1：（你可以選擇跳過到最后開始解決，那是正題）

以下是提示我的路經：

libtool: install: (cd /usr/local/lib && { ln -s -f libprotoc.so.9.0.1 libprotoc.so.9 || { rm -f libprotoc.so.9 && ln -s libprotoc.so.9.0.1 libprotoc.so.9; }; })
libtool: install: (cd /usr/local/lib && { ln -s -f libprotoc.so.9.0.1 libprotoc.so || { rm -f libprotoc.so && ln -s libprotoc.so.9.0.1 libprotoc.so; }; })

----------------------------------------------------------------------
Libraries have been installed in:
/usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
/bin/mkdir -p '/usr/local/bin'
/bin/bash ../libtool --mode=install /usr/bin/install -c protoc '/usr/local/bin'
libtool: install: /usr/bin/install -c .libs/protoc /usr/local/bin/protoc
/bin/mkdir -p '/usr/local/include'
/bin/mkdir -p '/usr/local/include/google/protobuf'
/usr/bin/install -c -m 644 google/protobuf/descriptor.proto '/usr/local/include/google/protobuf'
/bin/mkdir -p '/usr/local/include/google/protobuf/compiler'
/usr/bin/install -c -m 644 google/protobuf/compiler/plugin.proto '/usr/local/include/google/protobuf/compiler'
/bin/mkdir -p '/usr/local/include'
/bin/mkdir -p '/usr/local/include/google/protobuf/compiler/cpp'

但是依舊沒有改變版本，沒有覆蓋住。

以下是我的protobuf現狀：

博客一：http://blog.csdn.net/elysion122/article/details/64523339的說法只能改變使用sudo命令下的提取位置，而且我還不知道怎么編我自己的路徑。

http://blog.csdn.net/whoamiyang/article/details/52947225我的安裝來源液體到了路徑，不過我懷疑其實我都沒有安裝上，由於我的版本比較新，所以我打算用pip把它卸載了，關鍵是我怎么讓caffe聽我的話去找protobuf用

我懷疑我的caffe用的是電腦的protobuf，在我用sudo make all的時候提示我語言不通，因為我這時用的是2.5的protobuf，用的是博客一的默認路徑Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin

當我用make all的時候提示我升級版本。如果我能夠知道我的caffe上哪里找的protobuf就好了。

知乎上這個也許可用，前提是我找到了對的protobuf：

我用cmake出現了
