Question

我已经完成并安装了CUDA，cuDNN，并按照我的指示进行了操作。我已添加了我认为需要的环境变量，但我似乎仍有问题。

我已经到了测试，看看是否已正确安装tensorflow。在拉出命令提示符时，键入python以使用shell，我键入import tensorflow as tf。

然后我得到了这个堆栈跟踪，这是我自己无法理解的问题。这是我需要社区帮助的地方：

>>> import tensorflow as tf
Traceback (most recent call last):
  File "C:\Users\Troy\AppData\Local\Programs\Python\Python36\lib\site-packages\tensorflow\python\platform\self_check.py", line 75, in preload_check

    self._handle = _dlopen(self._name, mode)

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-toolkit

Answer 1

请尝试安装CUDA 9.0。问题应该是CUDA 9.1版本。您可以从以下链接下载驱动程序：CUDA Toolkit 9.0

要卸载CUDA：

请运行以下命令：

 sudo apt-get --purge remove cuda
 sudo apt autoremove

这些命令应该能够从您的系统中卸载cuda。

如果您已将cuDNN配置为使用GPU：

您可以在设置过程中删除已复制到的目录中的文件。

这个堆栈跟踪告诉我什么是我的Tensorflow安装错误
