Tensorflow GPU Ubuntu安裝16.04錯誤（libcuda.so未找到）

Question

我已經安裝tensorflow的GPU版本，但是當我嘗試導入它，我收到以下錯誤信息：

I tensorflow/stream_executor/dso_loader.cc:125] successfully opened CUDA library libcublas.so.8.0 locally 
I tensorflow/stream_executor/dso_loader.cc:125] successfully opened CUDA library libcudnn.so.5 locally

I tensorflow/stream_executor/dso_loader.cc:125] successfully opened CUDA library libcurand.so.8.0 locally 

我也跟着安裝來自tensorflow網站的指導，並確保我已正確安裝Cuda和CudNN。

我已經嘗試創建從我在系統中找到的libcuda.so到NVIDIA網站上其他帖子上建議的cuda目錄的sym鏈接，但它們沒有幫助。

我也設置在〜/ .bashrc的參數export LD_LIBRARY_PATH="usr/local/cuda-8.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}"和export CUDA_HOME="/usr/local/cuda"但仍沒有運氣:(。

這將是最有幫助的，如果有人可以幫助我得到這個排序，因爲它是一個重要組成部分我的項目在我的GPU上運行的代碼。

有一個在你鍵入的LD_LIBRARY_PATH一個錯字，並tensorflow閱讀。我看到你有usr/local/cuda...代替/usr/local/cuda（請注意，在路徑的開始/）

Usuall對於我來說，使用nvidia的runfile安裝程序安裝cuda後，以下LD_LIBRARY_PATH就足夠了。 export LD_LIBRARY_PATH=/usr/local/cuda:/usr/local/cuda/lib64:$LD_LIBRARY_PATH
