我已经安装了Tensorflow，但无法将其导入Python：ImportError：无法从“ google.protobuf”（未知位置）导入名称“ descriptor”

Question

我已在Windows 10笔记本电脑中成功安装Tensorflow：

(base) C:\WINDOWS\system32>pip install tensorflow-gpu

但是，当我尝试将其导入Python时，出现错误消息：

C:\WINDOWS\system32>conda activate base

(base) C:\WINDOWS\system32>python
Python 3.7.4 (default, Aug  9 2019, 18:34:13) [MSC v.1915 64 bit (AMD64)] :: Anaconda, Inc. on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import tensorflow
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'tensorflow'
>>>

运行conda list会得到：

更新

我遵循下面的Rachayita的建议，但是我已经安装了Tensorflow 1.4，我想要tensorflow-gpu 2.0

在我的基本Anaconda环境中，我卸载了tensorflow-gpu 2.0，该软件已安装，然后按照官方tensorflow文档使用pip重新安装。

当我尝试在python中导入它时，出现以下错误消息：

Answer 1

您应该通过在Anaconda提示符下运行以下命令将其与Anaconda一起安装：

> conda create -n tf-gpu tensorflow-gpu
> conda activate tf-gpu

这是完整的文档-https://docs.anaconda.com/anaconda/user-guide/tasks/tensorflow/

Answer 2

您必须使用pip install tensorflow而非tensorflow-gpu安装tensorflow

Answer 3

在“ conda激活基础”之后运行“ pip install tensorflow-gpu”吗？

否则，这就是您需要做的，因为tensorflow不会安装在您的虚拟环境“基础”中。
