Training LeNet on MNIST with Caffe：

wangxiao@wangxiao-Aspire-VN7-591G:~$ sh /home/wangxiao/Downloads/caffe-master/examples/mnist/create_mnist.sh
Creating lmdb…
/home/wangxiao/Downloads/caffe-master/examples/mnist/create_mnist.sh: 16: /home/wangxiao/Downloads/caffe-master/examples/mnist/create_mnist.sh: build/examples/mnist/convert_mnist_data.bin: not found

Done.
然而，convert_mnist_data.bin 就在那里哇。。。
于是乎：百度一下： 鏈接：http://blog.sciencenet.cn/blog-1583812-843207.html
然后就成功了 。。。
Unzipping…
gzip: stdin: unexpected end of file
tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now
Done.
tar.gz 是用tar命令將源碼文件打包成一個文件，然后用zip命令壓縮成一個壓縮包，所以在安裝前要解壓縮，命令如下：tar -xvzf test.tar.gz完成后會生成一個解壓縮后的目錄，進入該目錄，查看readme文件或者install文件，里面有詳細的安裝命令。一般的安裝步驟是./configure 回車make 回車make install 回車make clean 回車如果configure沒有通過，說明你的系統環境沒有達到要求，該軟件所依賴的文件沒有被安裝，需要根據提示信息來具體分析。以上的各個命令只是最常用的使用方式，還有比較實用的參數沒有介紹，可以自己查看幫助文檔。

換了一種輸入方式，可以了，然而出現了另一種錯誤：

繼續Baidu啊，搜到了，然并卵。。。
License checkout failed.
License Manager Error -8
Make sure the HostID of the license file matches this machine, and that the HostID on the SERVER
line matches the HostID of the license file.
Troubleshoot this issue by visiting:
http://www.mathworks.com/support/lme/R2014b/8
Diagnostic Information:
Feature: MATLAB
License path: /home/wangxiao/.matlab/R2014b_licenses:/usr/local/MATLAB/R2014b/licenses/license.dat:/usr/local/MATL
AB/R2014b/licenses/license_wangxiao-System-Product-Name_406917_R2014b.lic:/usr/local/MATLAB/R2014b/l

Licensing error: -8,523.
解決方案為：
Linux Copy/overwrite libmwservices.so ( from the linux folder provided ) to : /usr/local/MATLAB/R2014A/bin/glnxa64…
然而 在復制的時候，提示我沒有權限阿，查看文件夾屬性，發現： you are not the owner, you don’t have the access …
shit 。。。
只好用終端命令了，sudo cp xxx /libmwservices.so /usr/local/MATLAB/R2014A/bin/glnxa64
即可 。。。
那么如何設置 從終端啟動 matlab 呢？
sudo ln -s /usr/local/Matlab/bin/matlab(你的安裝位置) /usr/bin/
打開的過程中報錯：
直接輸入：
rehash toolboxcache
然后關掉終端，重新打開matlab,就可以進來了。別問我為什么，我也不知道。。。。
