首先，我将尽力为您提供尽可能多的信息。我目前正在尝试在 windows 上为Python使用 tensorflow 模块。我知道该模块仅与 python 3.5 兼容，我已成功将其安装在D驱动器上的 virtualenv 中。现在这是问题所在，当我想在命令提示符下导入tensorflow时，它会说：
>>> import tensorflow
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

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-90-download-archive
现在我已经在发生此错误之后安装了Cuda，我认为安装成功了，但是我仍然收到此错误，为什么有这个主意？
