- 这个方法虽然简单,但是我们有完美的利用anaconda的解决方案,能够解决服务器上大家版本冲突,你想要几个环境就可以建立几个完全不冲突的环境,算是一本万利,教程在http://www.cnblogs.com/SweetBeens/p/8650460.html,推荐用这种方法。当然docker更好一些,但是老代码是没有docker文件的。
- 从头说起:
如何看你的需要安装的版本呢,上图:
注意看我的文件的路径,这就是caffe官网上的那句命令行出处:
for req in $(cat requirements.txt); do pip install $req; done
鉴于我用的是segnet作者自己改的python版本的caffe,所以这是我的目录,你可以穷搜,然后自己挑一个看看需要安装什么。按理说照着我这个txt,不论我什么版本的都该好使,但是没准我的txt找的不对,或者protobuf不向后兼容了,或者caffe找的anaconda的protobuf,版本有问题,总之我越来越想看有没有caffe配置更详细的官方原文doc,或者我应该看看linux from scrach。这种盲人摸象式解决问题损失了很多乐趣。
- 我现在开始折腾我们实验室的服务器,里面的protobuf版本比较高,所以我要用2.6.1的,我首先用下面连接的方法安装了2.6.1:(你可以选择跳过到最后开始解决,那是正题)

博客一:http://blog.csdn.net/elysion122/article/details/64523339的说法只能改变使用sudo命令下的提取位置,而且我还不知道怎么编我自己的路径。
http://blog.csdn.net/whoamiyang/article/details/52947225我的安装来源液体到了路径,不过我怀疑其实我都没有安装上,由于我的版本比较新,所以我打算用pip把它卸载了,关键是我怎么让caffe听我的话去找protobuf用
我怀疑我的caffe用的是电脑的protobuf,在我用sudo make all的时候提示我语言不通,因为我这时用的是2.5的protobuf,用的是博客一的默认路径Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin
当我用make all的时候提示我升级版本。如果我能够知道我的caffe上哪里找的protobuf就好了。
知乎上这个也许可用,前提是我找到了对的protobuf:

折腾了全部的路径也不管用。
开始解决
本教程适用于折腾半天还不管事,无奈之举。以及不能卸载(与别人共用服务器)
中心思想,找到系统认准的protoc,用你想要的版本替换他。
你需要
1.你需要的protobuf版本
2.该版本被你安装在哪
3.你系统认准的protobuf版本在哪
4.告诉你的系统,去哪里找lib
1安装你需要的protobuf
这个没什么好说的,不过提醒你最好用prefix装在你指定的目录,.configure --help看看怎么用prefix
./configure --prefix=/root/LT
2.找到你刚安装的protobuf
进入他的lib文件夹:
比如我就不同寻常的装到了LT文件夹里:不走寻常路,记住这个protoc。
3.找到你系统认定的protoc在哪
终端输入:
你也可以用命令行,找到这个protoc,给他改个名字,比如protoc_origin,然后把你想要的版本粘贴过来.这时候再输入
protoc --version
4.在/etc/ld.so.conf.d文件夹里面创建libprotobuf.conf
我在LT这么一个奇葩文件夹里面安装的,前面已经说过,所以我的lib也在这。所以我要在里面输入/root/LT/lib
这时候版本就变了。由于不能卸载,所以我尝试过各种办法,然而都不好使。
如果你用caffe,请不要在makefile.config中用anaconda,要自己配置各种前置,不过没准你就好使了呢。
为什么说无奈之举呢,因为这不是作者给的。而且是身首分离的,改变不了系统认准的地址,只能替换。我试过bashrc,命令行暂时的export也试过,都不能让系统上LT找protobuf。不走常规的方式可能有风险。
