無法在Torch中導入（需要）'cutorch'

我的機器上安裝了CUDA 7.5，並按照說明here安裝了Torch。在安裝Torch之前，我將CMake升級到版本3.2.x.x.然後，我用下面的命令安裝cutorch和cunn：無法在Torch中導入（需要）'cutorch'

luarocks install cutorch 
luarocks install cunn

在安裝cutorch我看到一些消息說say8ing CUDA 7.5在我的機器上找到。然而，我無法用require 'cotorch導入cutorch並得到以下錯誤，當我嘗試使用在終端中炬（TH）解釋器來運行它：

THCudaCheck FAIL file=/tmp/luarocks_cutorch-scm-1-8316/cutorch/lib/THC/THCGeneral.c line=17 error=30 : unknown error 
/home/amir/torch/install/share/lua/5.1/trepl/init.lua:384: cuda runtime error (30) : unknown error at /tmp/luarocks_cutorch-scm-1-8316/cutorch/lib/THC/THCGeneral.c:17 
stack traceback:

    ...amir/torch/install/lib/luarocks/rocks/trepl/scm-1/bin/th:199: in main chunk 
    [C]: at 0x00406670

然後我跟着指示here才能夠使用Eclipse編寫Lua/Torch代碼。在那裏，我試圖執行require 'cutorch'當出現以下錯誤：但

qlua: /home/amir/torch/install/share/lua/5.1/cutorch/init.lua:2: cannot load '/home/amir/torch/install/lib/lua/5.1/libcutorch.so' 
stack traceback:

    /home/amir/workspace/test/src/main.lua:2: in function 'main' 
    /home/amir/workspace/test/src/main.lua:6: in main chunk

這是文件libcutorch.so是在提到目錄。 This也沒有幫我解決這個問題。有誰知道我應該着手解決這個問題嗎？

當我進入luarocks list我得到如下：

做'LDD /家庭/阿米爾/手電筒/在終端安裝/ lib中/ LUA/5.1/libcutorch.so'，看看它是否被正確鏈接到所有如果它的依賴。 – siavashk

@siavashk看起來這是正確地鏈接到所有的依賴關係。當我運行命令時，我得到的東西像'libluaT.so => /home/amir/torch/install/lib/libluaT.so（0x00007fd568c94000）' – Amir

好了，這裏是你如何能解決問題（感謝阿爾desmaison上Torch7谷歌組）：

請務必遵循我在問題中提到的所有步驟都是爲了確保CUDA正確安裝。
如果您已經安裝Theano，執行sudo python
然後做import theano
然後去CUDA樣本文件夾，make一個樣品（無所謂哪一個）
然後做./[name_of_the_sample]
然後火炬將能夠輕鬆地使用CUDA後端

如果你沒有安裝 Theano，嘗試運行CUDA示例使用sudo。 重要步驟是能夠運行其中一個CUDA示例。

現在你全部設置！

這是否意味着在運行任何CUDA示例之前，CUDA實際上並不是完全建成？ – matanster

不，我認爲一些CUDA庫的鏈接丟失。雖然有辦法解決這個問題，但我不記得如何 – Amir

嘗試sudo bash /torch/update.sh
