安裝Tensorflow-GPU時出錯

Question

我正在嘗試按照以下說明安裝tensorflow和tensorflow-gpu：

https://www.tensorflow.org/install/install_windows#CommonInstallationProblems

我認為我正確地跟隨了他們，但是我似乎無法使其正常工作。 如果我從CMD提示符下以管理員身份運行它，兩者似乎都安裝成功。 如果我僅安裝了tensorflow后就停止了，那就可以了。 但是一旦我還安裝了tensorflow-gpu（即使它似乎安裝成功），當我嘗試使用tensorflow時也會出現錯誤。

這是我得到的錯誤：

我正在通過以管理員身份運行並帶有激活運行的CMD提示符進行此安裝。 我在PyCharm中也嘗試過類似的結果。

說明說即使我計划使用tensorflow-gpu，也應該安裝常規的tensorflow。

但是我嘗試僅安裝tensorflow-gpu，盡管安裝成功，但運行“將tensorflow作為tf導入”時仍然出現上述錯誤。

因此，我似乎可以使它正常工作的唯一方法是不安裝tensorflow-gpu。 但是，這樣做的全部原因是我可以將我的NVIDIA GPU與Keras / Tensorflow結合使用。

注意：我確實安裝了CUDA Toolkit 8.0和cuDNN v5.1，盡管該過程很麻煩，所以可能我做錯了。 我認為沒有簡單的方法可以驗證它。

對於踢，我嘗試先安裝tensorflow-gpu，然后在僅安裝tensorflow時遇到以下錯誤-盡管是管理員，這是一個權限錯誤：

這個問題是一個類似的問題： Tensorflow GPU安裝錯誤Windows 10 Anaconda

但是，我確實確保我的路徑指向正確的位置。

Answer 1

好吧，我已修復它，盡管老實說，我不確定我嘗試過哪種方法。

我再次仔細地執行了步驟。 盡管它可能已經解決了一些先驅問題，但仍然沒有任何效果。 然后，我進入路徑環境變量並開始添加新路徑，以便Tensorflow可以更輕松地在Conda環境中為Keras / Tensorflow查找內容。 特別是，我查找了文件“ pywrap_tensorflow”（找不到的文件）並找到了它，並添加了特定路徑。 我不知道這是否必要。 但最后，它成功了，我現在可以運行tensorflow gpu。
