2.0兼容方案:

在终端(Linux/MacOS)或命令提示符(Windows)中执行以下命令，使用Pip安装Tensorflow 2.0:

#Install tensorflow using pip virtual env 
pip install virtualenv
virtualenv tf_2.0.0   # tf_2.0.0 is virtual env name
source tf_2.0.0/bin/activate
#You should see tf_2.0.0 Env now. Execute the below steps
pip install tensorflow==2.0.0
python
>>import tensorflow as tf
>>tf.__version__
2.0.0

在终端(Linux/MacOS)或命令提示符(Windows)中执行以下命令，使用Bazel安装Tensorflow 2.0:

git clone https://github.com/tensorflow/tensorflow.git
cd tensorflow

#The repo defaults to the master development branch. You can also checkout a release branch to build:
git checkout r2.0

#Configure the Build => Use the Below line for Windows Machine
python ./configure.py 

#Configure the Build => Use the Below line for Linux/MacOS Machine
./configure
#This script prompts you for the location of TensorFlow dependencies and asks for additional build configuration options. 

#Build Tensorflow package

#CPU support
bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package 

#GPU support
bazel build --config=opt --config=cuda --define=no_tensorflow_py_deps=true //tensorflow/tools/pip_package:build_pip_package

我的环境:Win 10, python 3.6

pip3 install --upgrade tensorflow
pip install --upgrade tensorflow

错误:

> Collecting tensorflow Could not find a version that satisfies the
> requirement tensorflow (from versions: ) No matching distribution
> found for tensorflow

我还尝试了pip install tensorflow和pip install tensorflow-gpu。 但错误:

> Could not find a version that satisfies the requirement tensorflow (from versions: ) No matching distribution found for tensorflow
> Could not find a version that satisfies the requirement tensorflow-gpu (from versions: ) No matching distribution found for tensorflow-gpu

使用Step (https://www.tensorflow.org/install/install_windows)尝试安装OK

Follow the instructions on the Anaconda download site to download and install Anaconda. https://www.continuum.io/downloads Create a conda environment named tensorflow by invoking the following command: C:> conda create -n tensorflow pip python=3.5 Activate the conda environment by issuing the following command: C:> activate tensorflow (tensorflow)C:> # Your prompt should change Issue the appropriate command to install TensorFlow inside your conda environment. To install the CPU-only version of TensorFlow, enter the following command: (tensorflow)C:> pip install --ignore-installed --upgrade tensorflow To install the GPU version of TensorFlow, enter the following command (on a single line): (tensorflow)C:> pip install --ignore-installed --upgrade tensorflow-gpu

至少在我写这篇文章的时候(2020年12月)，Tensorflow不支持3.8之后的python版本。使用这个:https://www.tensorflow.org/install来检查它支持哪些python版本，我只是花了几个小时来查看这些答案，花了我很长时间才意识到这一点。

如果你试图在windows机器上安装它，你需要有64位版本的python 3.5。这是真正安装它的唯一方法。来自网站:

TensorFlow仅支持Windows上的64位Python 3.5。我们已经用以下Python发行版测试了pip包: Anaconda的Python 3.5 Python 3.5来自python.org。

你可以从这里下载合适的python版本(确保你选择了一个写着“Windows x86-64”的版本)

现在，您应该能够使用pip install tensorflow或python -m pip install tensorflow进行安装(如果同时安装了python2和python3，请确保您使用的是从python3安装的正确pip)

请记住安装Anaconda 3-5.2.0作为最新版本，即3-5.3.0，包含Tensorflow不支持的python 3.7版本。

我发现这个方法终于管用了。

python3 -m pip install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-1.12.0-py3-none-any.whl

编辑1:这是在Windows (8,8.1, 10)， Mac和Linux上测试的。根据您的配置将python3更改为python。如果使用Python 2.x，则将url中的py3更改为py2。

编辑2:不同版本的列表，如果有人需要:https://storage.googleapis.com/tensorflow

编辑3:可用轮子包的url列表可在这里: https://www.tensorflow.org/install/pip#package-location

从今天开始，如果还有人想知道， Python >= 3.9也会导致同样的问题 卸载python 3.9，然后安装3.8，应该会解决这个问题
