我不得不卸载Python 3.6.1并安装3.5.0，因为这是适用于TensorFlow的唯一版本。我正确地改变了我的路径，并且在我成功安装了第一个软件包（numpy）后，出现了这个错误（前两行）。我试图这样做，因为它说和发生错误（如下图），并试图安装熊猫和numpy的（abowe）：Pip错误：应升级pip，pandas和matplotlib，但返回错误

You are using pip version 7.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip'
comm
and.
我试图下载轮，然后再安装它：
C:\Users\Downloads>pip install matplotlib-2.0.2-cp36-cp36m-win32.whl
matplotlib-2.0.2-cp36-cp36m-win32.whl is not a supported wheel on this
platform.
也试过与64 BT版本，同样的故事。
任何想法该怎么做，它甚至意味着什么？
包名之间的逗号造成所有错误。查看我的答案完整的步骤。一个过时的pip版本似乎并不是这里的主要问题 – aim100k
