學習筆記之 初試Linux遇到的問題 2015-10-13，linux2015-10-13

1. 安裝.deb檔案，用sudo gdebi XXX.deb

sudo apt-get install xxx

2.需要配置系統路徑：

LD_LIBRARY_PATH=.../lib:LD_LIBRARY_PATH

exportLD_LIBRARY_PATH

3.ln -sf xxx xxx 軟連結

4. Training LeNet onMNIST with Caffe：

wangxiao@wangxiao-Aspire-VN7-591G:~$sh/home/wangxiao/Downloads/caffe-master/examples/mnist/create_mnist.sh

Creatinglmdb...

/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

/home/wangxiao/Downloads/caffe-master/examples/mnist/create_mnist.sh:18:/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就在那裡哇。。。

 

 

 

 

 

 

 

於是乎：百度一下：連結：http://blog.sciencenet.cn/blog-1583812-843207.html

 

 

 

 

 

 

 

 

 

 

 

 

然後就成功了。。。

Unzipping...

gzip:stdin: unexpected end of file

Done.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

6.Linux怎麼安裝.tar.gz軟體

tar.gz是用tar命令將源碼檔案打包成一個檔案，然後用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-xvzftest.tar.gz完成後會產生一個解壓縮後的目錄，進入該目錄，查看readme檔案或者install檔案，裡面有詳細的安裝命令。一般的安裝步驟是./configure 斷行符號make 斷行符號makeinstall 斷行符號makeclean 斷行符號如果configure沒有通過，說明你的系統內容沒有達到要求，該軟體所依賴的檔案沒有被安裝，需要根據提示資訊來具體分析。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，可以自己查看協助文檔。

 

7.在cifa10這個資料集上又出現了類似的問題：

Done.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

換了一種輸入方式，可以了，然而出現了另一種錯誤：

wangxiao@wangxiao-Aspire-VN7-591G:~/Downloads/caffe-master$sh ./examples/cifar10/create_cifar10.sh

Creatinglmdb...

繼續Baidu啊，搜到了，然並卵。。。
