在Windows中安裝Tensorflow

Question

詳細信息。我在Windows 10上安裝，我使用pythong 3.5.4，我已經安裝了visual studio 15依賴項和.dll（除非我需要更改一些PATH變量）。我已經在路徑中更新了CUDA，併爲cuDNN安裝了相同的代碼。但是，我在通過conda環境安裝和pip安裝時遇到此錯誤。

看起來有些.dll文件沒有被正確調用，但我作爲，因爲我已經安裝了所有這些，真的檢查不確定。也許Visual Studio 15的依賴關係？

而且這是Tensorflow爲GPU

Answer 1

該錯誤通常與正在使用錯誤的cuDNN版本相關聯。

假設你使用發佈了最新的版本Tensorflow（即1.3.0），你需要使用cuDNN 6儘管Tensorflow安裝頁面告訴你使用5.1。由於他們針對所有二進制版本（or so their changelong claims）針對Tensorflow 6構建的最新版本，因此您應該使用它。

注意，你可以同時擁有cuDNN 5.1和安裝6（只是把它們放在兩個不同的文件夾，把文件夾b0th您PATH環境變量），因爲該.dll文件有不同的名稱，只有合適的人將被載入。
