我正在尝试使用pip安装TensorFlow:
$ pip install tensorflow --user
Collecting tensorflow
Could not find a version that satisfies the requirement tensorflow (from versions: )
No matching distribution found for tensorflow
我做错了什么?到目前为止,我使用Python和pip没有任何问题。

你需要一个64位版本的Python,在你的情况下,你使用的是32位版本。到目前为止,Tensorflow只支持64位版本的Python 3.5。X和3.8。Windows操作系统。请参阅安装文档以了解当前支持的内容
要检查您正在运行的Python版本,输入Python或python3启动解释器,然后输入import struct;print(struct.calcsize("P") * 8),这将打印32或64来告诉您正在运行的Python的比特版本。
评论:
要下载不同版本的Windows Python,请访问python.org/downloads/windows并向下滚动,直到看到以“64”结尾的版本。这将是64位版本,应该与张量流一起工作

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
试试这个:
export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.12.1-py3-none-any.whl
pip3 install --upgrade $TF_BINARY_URL

我可以在我的Mac上安装tensorflow-macos和tensrflow-metal
$ python -m pip install -U pip
$ pip install tensorflow-macos
$ pip install tensorflow-metal
您需要使用正确版本的Python和pip。
在Windows 10上,使用Python 3.6。X版本我也面临同样的问题,然后在仔细检查后,我注意到我的64位机器上安装了Python-32位。记住TensorFlow只兼容64位的Python安装,不兼容32位的Python版本
如果我们从python.org下载Python,默认安装为32位。所以我们必须手动下载64位安装程序来安装Python 64位。然后将以下内容添加到PATH环境中。
C:\Users\AppData\Local\Programs\Python\Python36
C:\Users\AppData\Local\Programs\Python\Python36\Scripts
然后在命令提示符下执行gpupdate /Force。如果Python命令不能用于64位,则重新启动计算机。
然后在命令提示符下运行python。它应该显示64位。
C:\Users\YOURNAME>python
Python 3.6.3 (v3.6.3:2c5fed8, Oct 3 2017, 18:11:49) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
然后执行以下命令安装tensorflow CPU版本(推荐)
pip3 install --upgrade tensorflow
2020年10月更新:
Tensorflow现在支持Python 3.5。通过Python 3.8。X,但您仍然必须使用64位版本。
如果需要在同一台机器上运行多个版本的Python,可以使用虚拟环境来帮助管理它们。
我的环境:Win 10, python 3.6
pip3 install --upgrade tensorflow
pip install --upgrade tensorflow
错误:

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
