python - 在 Windows 10 上使用 CUDA 9.1 和 Python 3.6 安装 Tensorflow

Question

我在安装 TensorFlow 时遇到此错误。编辑:我安装了 CUDA 9.0，并更改了包括 Path 变量在内的环境变量，现在它可以工作了。

    (tensorflow-gpu) C:\Users\Admin>python
Python 3.6.4 |Anaconda, Inc.| (default, Mar  9 2018, 07:43:39) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import tensorflow as tf
Traceback (most recent call last):

    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:

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

这是一个与此非常相似的问题。

Tensorflow installation with CUDA 9.1 and python 3.6

Answer 1

这类似于 Tensorflow import error

快速回答:默认情况下，NVidia 将安装最新版本的 CUDA，目前为 9.1

TensorFlow 预计为 9.0，如“ImportError: Could not find 'cudart64_90.dll'”所示 - 将其读取为 cuda-runtime-64-bit-version9.0 DLL

要解决此问题，请前往 NVidia 网站下载 9.0 版本的驱动程序，然后就可以开始使用了。我在这里写了一个指南:http://www.laurencemoroney.com/installing-tensorflow-with-gpu-on-windows-10/
