Python Tensorflow和Numpy缺失

我正在使用Ubuntu 14.04。我试图使用tensorflow模块，但尽管我已经安装了它，并且安装方式与安装任何其他pkg或模块的方式相同，但python并不认为它已安装。即使pip说它已经安装了。。。我不知道到底发生了什么事

你们自己看看：

$ sudo pip install tensorflow

编辑：不可能重复，因为发布的链接没有解决相同的问题。。。所以基本上，这是一个完全不同的问题。

仅仅因为您是virtualenv的源代码，这并不意味着'pip'命令将引用virtualenv的pip库。“pip”命令很可能仍然链接到默认的python解释器

您可以尝试以下操作以使其正常工作：

首先卸载两个模块：

[root@server] sudo pip uninstall tensorflow
[root@server] sudo pip uninstall numpy

然后找到你的虚拟电视：

[root@server] source ~/venv/activate

然后使用pip安装模块，同时显式调用python命令：

(venv)[root@server] python -m pip install tensorflow
(venv)[root@server] python -m pip install numpy

然后查看它们是否可用：

(venv)[root@server] python
>> import numpy

可能是@phd的重复不，我甚至不知道你为什么这么认为，甚至有些接近。那里的答案清楚地解释了什么时候应该使用

sudo

，什么时候应该使用

virtualenv

。你可以很容易地得到（而且你一定是谷歌搜索过）在虚拟环境中的

sudo

如果不是邪恶的话也是毫无意义的。您提到了在虚拟环境内外访问python模块的问题，但这正是虚拟环境所做的：从外部保护内部库。

[root@server] source ~/venv/activate

(venv)[root@server] python -m pip install tensorflow
(venv)[root@server] python -m pip install numpy

(venv)[root@server] python
>> import numpy
