我在安装 TensorFlow 时遇到了这个错误。编辑:我安装了 CUDA 9.0，并更改了我的环境变量，包括 Path 变量，现在它可以工作了。

ImportError: Could not find 'cudart64_90.dll'. TensorFlow requires that this DLL be installed in a directory that is named in your %PATH% environment variable. Download and install CUDA 9.0 from this URL: https://developer.nvidia.com/cuda-toolkit
这是一个与这个问题非常相似的问题。
