tensorflow.python.pywrap_tensorflow_internal没有模块Windows 10 tensorflow gpu

Question

“ tensorflow-cpu”在装有Windows 10的设备上正常运行。 我正在尝试安装tensorflow-gpu，安装后无法导入，显示以下错误。

  

tensorflow.python.pywrap_tensorflow_internal没有模块

我已经安装了以下内容

  

CUDA 10.1

     

Nvidia图形驱动程序419版

     

CUDnn for CUDA 10.1

     

VC ++ 2015 REDIST

谁能说我在这里想念的是完整的错误消息。

如果确定Windows计算机上已安装 Visual C ++ 2015 Redist ，则可能是 CUDA 版本与 Tensorflow 之间的版本冲突。强>版本。由于较新的版本存在一些冲突，并且在张量流方面更多，因此需要准确的CUDA版本和CUDnn库才能使其正常工作。

正确配置它的最佳方法是使用 Anaconda 安装和配置tensorflow-gpu，因为conda会自动为相应的tensorflow下载所有必需的CUDA和CUDnn版本

问题是新的Anaconda默认使用Python 3.7.x，而tensorflow或tensorflow-gpu不支持

因此安装Anaconda可以下载here

现在，通过在Anaconda Prompt中键入以下内容，使用配置了python 3.6.x的conda创建虚拟环境

conda create -n yourenvname python=3.6 anaconda

现在输入

即可切换到您的环境

conda activate yourenvname

现在使用来检查python版本，它应该显示类似这样的内容

> python --version
Python 3.6.7 :: Anaconda custom (64-bit)

现在终于安装tensorflow-gpu

conda install tensorflow-gpu

现在打开python并尝试导入tensorflow

>>> import tensorflow as tf
>>> sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))

恭喜！一切都准备好了。
