Installing with native pip If the following version of Python is not installed on your machine, install it now: Python 3.5.x from python.org TensorFlow only supports version 3.5.x of Python on Windows. Note that Python 3.5.x comes with the pip3 package manager, which is the program you'll use to install TensorFlow. To install TensorFlow, start a terminal. Then issue the appropriate pip3 install command in that terminal. To install the CPU-only version of TensorFlow, enter the following command:

C:\> pip3 install --upgrade tensorflow
To install the GPU version of TensorFlow, enter the following command:

C:\> pip3 install --upgrade tensorflow-gpu

如果你的命令pip install——upgrade tensorflowcompililes，那么你的tensorflow版本应该是最新的。我个人更喜欢用水蟒。tensorflow可以简单地安装和升级:

 conda install -c conda-forge tensorflow  # to install
 conda upgrade -c conda-forge tensorflow  # to upgrade

另外，如果你想用你的GPU使用它，你有一个简单的安装:

 conda install -c anaconda tensorflow-gpu

我已经用了一段时间了，从来没有任何问题。

如果您尝试了上面的解决方案，但没有解决问题，可能是因为版本不一致。

我安装了python 3.9，无法用pip安装tensorflow。

然后我卸载了3.9，然后安装了3.8.7，成功…tensorflow支持的最大版本是3.8。X(2021年) 所以，检查你的python版本是否与当前的tensorflow兼容。

我在OSX Sierra 10.12.2上遇到了这个问题。原来我安装的Python版本是错误的(我安装的是Python 3.4，但OSX的tensorflow pypi包只适用于Python 3.5及以上版本)。

解决方案是安装Python 3.6。下面是我让它工作的方法。注意:我使用Homebrew来安装Python 3.6，你也可以使用python.org上的Python 3.6安装程序来安装

brew uninstall python3
brew install python3
python3 --version # Verify that you see "Python 3.6.0"
pip install tensorflow # With python 3.6 the install succeeds
pip install jupyter # "ipython notebook" didn't work for me until I installed jupyter
ipython notebook # Finally works!

Python 3.7适合我，我卸载了Python 3.8.1，重新安装了3.7.6。之后，我执行:

pip3 install --user --upgrade tensorflow

这是可行的

通过勾选“添加python到路径”来安装python Pip3安装——升级https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.12.0-py3-none-any.whl

这适用于windows 10.0
