【问题标题】：Tensorflow appears to install but does not actually workTensorflow 似乎可以安装，但实际上并不能正常工作
【发布时间】：2020-06-26 20:38:04
【问题描述】：

我已经安装了张量流如下：

pip install --upgrade tensorflow

（以及添加以下在尝试排除故障时有效的内容）：

pip install tensorflow==2.0.0

当我打开 jupiter notebook 并输入：

import tensorflow as tf

但是当我尝试执行下一步并执行时，我没有收到错误消息

tf.Session()

它向我抛出了以下错误（将其中的一部分剪掉以适应消息，但它似乎到处都是重复的）：

ERROR:root:Internal Python error in the inspect module.

【问题讨论】：

如果您使用 Anaconda/Conda，为什么要使用 pip 安装 TensorFlow？

标签： python python-3.x tensorflow keras tensorflow2.0

【解决方案1】：

代码 pip install --upgrade tensorflow

为您的系统全局安装 pip。您可以通过在任何地方创建一个 .py 文件并在下面编写以下代码来确认这一点， import tensorflow as tf

你也可以通过在 shell 中运行 'python' 来测试它，然后运行上面的命令。

关于点子

需要注意的是，使用 pip 和使用 anaconda 是有明显区别的。 pip 是 Python 的“package manager”，一个用于从 pypi.org 设置包的 CLI 工具。

您可以使用 pip 在本地设置软件包作为您机器上文件系统上的 repo，或者您可以全局安装这些软件包（安装一次，在您机器上的任何位置运行）。全局安装时会出现某些缺点。为此，使用了“virtualenv”。请咨询the python doc 寻求帮助。

关于康达

它是一个主要用于数据科学项目的包管理器，主要与 Anaconda 一起提供，Anaconda 是 Jupyter 和 Spyder 笔记本的 GUI 提供程序。见anaconda here。

混乱

Jupyter 笔记本使用 conda“虚拟环境”，您假设 Jupyter 将能够获取您使用 pip 安装的软件包，但事实并非如此。

解决方案是制作一个 Conda 虚拟环境

为此，请咨询conda docs。创建虚拟环境后，请确保在使用适当的 python 解释器激活 conda 虚拟环境后安装 tensorflow 包。打开 Jupyter Notebook 并寻找一个选项来选择该虚拟环境，然后就可以开始了。

希望对你有帮助！

【解决方案2】：

我在使用 pip 安装 Tensorflow 2 时遇到了类似的问题。请改用 CONDA 安装 Tensorflow 2。 Conda 安装了 Tensorflow 2 的所有依赖项，包括 GPU 操作所需的 Nvidia CUDNN 模块。如前面的答案所述，使用 Anaconda 创建虚拟环境，然后使用 conda 将 Tensorflow 安装到该环境中
