Python Windows 10 Tensorflow（Anaconda）GPU不工作

在我的机器上安装tensorflow gpu时遇到很多问题。Tensorflow 1.3工作得非常完美，但当我尝试使用Tensorflow gpu时，最终出现以下错误：

ImportError: Traceback (most recent call last):
  File "C:\Users\Freddie\Anaconda3\envs\tensorflow\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 18, in swig_import_helper
    return importlib.import_module(mname)

During handling of the above exception, another exception occurred:

这里似乎什么都没用。

我找到了正确的答案。问题是我正在运行代码，但anaconda下的PATH变量不包括CUDA8

bin

目录

为了解决这个问题，我创建了一个名为CUDA_8_HOME的环境变量，设置为

bin

dir的路径，然后将其添加到脚本的顶部：

import os
os.environ["PATH"] = os.environ["PATH"] + os.environ["CUDA_8_HOME"]

from keras import backend as K
import tensorflow as tf
<... Script Continues ...>

导入操作系统
os.environ[“PATH”]=os.environ[“PATH”]+os.environ[“CUDA_8_HOME”]
从keras导入后端为K
导入tensorflow作为tf

---

事实证明，使用windows对话框（在“开始”菜单中搜索环境变量）将CUDA home（

bin

目录）添加到路径也可以起作用。

这不是一个简单的解决方案，您可能已经看到了这一点，但相关的Github问题是@PeteWarden我找到了我的问题的解决方案，详细说明如下：

import os
os.environ["PATH"] = os.environ["PATH"] + os.environ["CUDA_8_HOME"]

from keras import backend as K
import tensorflow as tf
<... Script Continues ...>
