引言： Tensorflow大名鼎鼎，这里不再赘述其为何物。这里讲描述在安装python包的时候碰到的“No matching distribution found for tensorflow”，其原因以及如何解决。

第一种解决方案

简单的安装tensorflow

这里安装的tensorflow的cpu版本，gpu版本可以自行搜索安装指南，或者参考如下指令：

pip3 install tensorflow #cpu

这里使用的python 3.6.3版本。

pip3 install tensorflow-gpu

这里是gpu的版本。

window的环境

window 7.

问题描述：

pip3 install tensorflow

如此简单的指令，应该不会出错吧，结果得到如下错误信息：

Collecting tensorflow

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

为什么没有找到tensorflow呢？那我们自行找找看吧？

pip3 search tensorflow

悲伤的我如此难以自抑，明明可以找到的，怎么却无法安装嗯？我需要自行好好找找明明是谁？ ：-）

问题分析

二话不说，直接上官网上查查看，虽然官网离我朝远隔万里，需要跋山涉水之后方可达到。翻过拿到看不见的墙之后，重要可以看到官方信息了。

官方路标如下： /install/install_windows

其中所提安装步骤非常简洁，如此简洁的步骤，怎么可能出错？ 于是重新梳理了一下，难道是Python或者pip3本身的问题吗？

check pip3

pip –version

发现其为最新版本：

pip 9.0.1 from d:\program files (x86)\python\lib\site-packages (python 3.6)

那Python呢？ 官方文档中提到如下：

If one of the following versions of Python is not installed on your machine, install it now:

* Python 3.5.x 64-bit from

* Python 3.6.x 64-bit from

难道我安装的python是假python不成？ 估计有可能吧，难道是64bit的问题？

检查python的版本

python -v

得到了python的完整信息：

..........................................

Type "help", "copyright", "credits" or "license" for more information.

import 'atexit' # <class '_frozen_importlib.BuiltinImporter'>1234567891011121314151617

其中关于python的关键信息：

Python 3.6.3 (v3.6.3:2c5fed8, Oct 3 , 17:26:49) [MSC v.1900 32 bit (Intel)] on win32

“32bit” !!! 一口老血喷出，众里寻他千百度，蓦然回首bug正在这灯火阑珊处。原来是python版本的问题导致的。

修复问题

重新下载一个64bit的python版本，之后重新操作就可以了。

python -v

查看其中的关键信息：

Python 3.6.4 (v3.6.4:d48eceb, Dec 19 , 06:54:40) [MSC v.1900 64 bit (AMD64)] on win32

确认是64位，没有问题。

然后直接安装tensorflow:

pip3 install tensorflow

安装过程如下：

C:\windows\system32>pip3 install tensorflow

然后大家就可以愉快地写代码了.

第二种解决方案

直接使用源路径下载：python -m pip install --upgrade /tensorflow/mac/cpu/tensorflow-1.12.0-py3-none-any.whl

Error importing tensorflow. Unless you are using bazel, you should not try to import tensorflow from its source directory; please exit the tensorflow source tree, and relaunch your python interpreter from there.

mac 系统OS X EI capitan时遇到一些问题：

1. 采用pip安装，进行到利用pip install tensorflow时报错:

sudo方式同样无效，推测可能是OSX的安全策略导致修改系统目录权限失败？采用VirtualEnv凡是安装

2. 按照官网VirtualEnv方式完成安装后。运行Python，测试是否安装成功时：

>>> import tensorflow as tf

会报错：

Error importing tensorflow. Unless you are using bazel,you should not try to import tensorflow from its source directory;please exit the tensorflow source tree, and relaunch your python interpreterfrom there.

解决方案参考@raingo 解释，需要先reinstall protobuf后再reinstall Tensorflow：

- pip install -U protobuf==3.0.0b2- pip install --upgrade $TF_BINARY_URL

注意由于是VirtualEnv安装方式，需要先启动VirtualEnv。
