tensorflow.python.pywrap_tensorflow_internal无模块windows 10 tensorflow gpu

Question

"tensorflow-cpu“在我的windows 10设备上正常工作。我试图安装tensorflow-gpu，安装后它无法导入，显示了以下错误。

tensorflow.python.pywrap_tensorflow_internal no模块

我已经安装了以下程序

库达10.1 Nvidia图形驱动程序版本419 CUDnn用于数据自动化系统10.1 VC++ 2015 REDIST

有人能说我在这里缺少的是完全的错误信息吗？

如果您确实在您的Windows计算机上安装了Visual C++ 2015 Redist，那么可能是CUDA版本与Tensorflow版本之间的版本冲突。因为较新的版本在tensorflow上存在一些冲突和更多的冲突，因此需要准确的CUDA和CUDnn库版本才能正常工作。

正确配置它的最佳方法是使用Anaconda来安装和配置tensorflow-gpu，因为conda将自动下载相应的tensorflow所需的of和CUDnn的所有版本。

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

所以安装Anaconda你可以下载它这里

现在，通过在Anaconda提示符中键入以下命令，使用conda和python 3.6.x创建一个虚拟环境

conda create -n yourenvname python=3.6 anaconda

现在通过输入更改到您的环境。

conda activate yourenvname

现在检查python版本，使用它应该向您展示如下内容

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

现在终于安装了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))

恭喜你！你们都准备好了。
