python - ImportError:找不到“cudnn64_7.dll”

我遇到以下错误：

 Traceback (most recent call last):   File
 "C:\Anaconda\envs\tensorflow\lib\site-packages\tensorflow\python\platform\self_check.py",
 line 87, in preload_check
     ctypes.WinDLL(build_info.cudnn_dll_name)   File "C:\Anaconda\envs\tensorflow\lib\ctypes\__init__.py", line 348, in
 __init__
     self._handle = _dlopen(self._name, mode) OSError: [WinError 126] The specified module could not be found

 During handling of the above exception, another exception occurred:

     % (build_info.cudnn_dll_name, build_info.cudnn_version_number)) 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

我已经在％Path％环境中提到的目录中安装了所需的“ cuDNN 7”文件，但是该语句

import tensorflow as tf

不管用。我已经从上述站点下载了cuDNN 7文件：

https://developer.nvidia.com/cudnn

我已经遍历了StackOverflow上的所有答案，但是却遇到了相同的错误。
请指导我如何运行以上声明。

最佳答案

您是否已导出PATH？有时，我们没有注意到这些小细节。
