無法將導入張量流作為tf運行

Question

我使用以下命令安裝了tensorflow。

pip install tensorflow

我正在運行一個簡單的程序

import tensorflow as tf
node1 = tf.constant(3.0, tf.float32)
node2 = tf.constant(4.0) # also tf.float32 implicitly
print(node1, node2)

運行程序時出現以下錯誤。

我已經更新了pip，並且正在python 3.5上運行程序

Answer 1

該錯誤消息通常意味着在您的系統上找不到TensorFlow的依賴項之一。 由於您在Windows上使用TensorFlow的僅CPU版本，因此最有可能丟失的DLL是msvcp140.dll ，該文件是運行使用Microsoft Visual C ++ 2015編譯的程序所必需的。此DLL通常作為Visual Studio的一部分安裝在開發人員計算機上，或某些Python發行版，例如Anaconda。 但是，適用於Windows的Python的Python.org發行版不包含它。

您可以通過下載並安裝Microsoft Visual C ++ 2015 Redistributable Update 3在系統上安裝msvcp140.dll 。

對於其他找到此答案的人，請注意， 此腳本可以幫助診斷Windows上常見的TensorFlow安裝問題。

Answer 2

我不確定是什么問題，並且可能與您對錯誤消息一無所知，但是當您使用python 3.x時，不應該通過以下方式安裝tensorflow：

pip3 install tensorflow

要查看您是否正在使用pip3，請輸入：

pip3 -V

如果您需要更多幫助，請訪問Mac或Linux的官方教程。

我希望這有幫助
