我在WIN10 cp上成功安装了Tensorflow，但是当我尝试导入Tensorflow时，出现导入错误，如下所示：

ImportError: Could not find 'cudnn64_7.dll'. TensorFlow requires that this DLL be installed in a directory that is named in your %PATH% environment variable. Note that installing cuDNN is a separate step from installing CUDA, and this DLL is often found in a different directory from the CUDA DLLs. You may install the necessary DLL by downloading cuDNN 7 from this URL: https://developer.nvidia.com/cudnn

我已经安装了CUDA v9.2和cuDNN 7，也可以找到“ pywrap_tensorflow_internal.py”，当我安装了Tensorflow的CPU版本时，它运行的很好，但它不适用于tensorflow gpu。可能出什么问题了？
答案 0 :(得分：1)
问题解决了。 我用7.0.4重新安装了CUDA V9.0和cuDNN 然后用重新安装tensorflow-gpu pip卸载tensorflow-gpu pip install tensorflow-gpu
