在Ubuntu 16.04上安装Tensorflow

Question

我曾试过在Ubuntu 16.04上安装Tensorflow，但是…

我使用了sudo -H命令，因此我不明白为什么会出现这种情况。 我的Python安装。

你可能安装了不止一个Python版本--默认版本和Anaconda版本，尝试使用/usr/bin/python或者/usr/local/bin/python而不是直接使用python。 - Yaroslav Bulatov

@YaroslavBulatov 是的，我已经安装了Miniconda。 - Richard Rublev

所以我猜其中一个在sys.path中有/usr/local/lib/python2.7/dist-packages，而另一个没有，因此另一个看不到tensorflow。 - Yaroslav Bulatov

@YaroslavBulatov bash：cd：/usr/local/bin/python：没有那个文件或目录 - Richard Rublev

Anaconda使用自己的路径来存储软件包，因此在Anaconda上安装TensorFlow略有不同。关于此问题，在“[tensorflow] anaconda”上已经有了一些解答。 - Yaroslav Bulatov

Answer 1

这个教程对我很有用。

我使用的是Anaconda 2.7版本，并创建了一个虚拟环境（如果需要可以使用py3和python=3.5）：

conda create --name py2 python=2.7 anaconda

在安装之前（以及之后使用！）不要忘记激活它：

source activate py2

我建议升级scikit-learn和libgcc:

conda upgrade scikit-learn libgcc

接着按照链接的教程进行操作。

我认为自从你5个月前提问以来，情况已经发生了很大变化，但我希望这篇文章能够帮助到那些偶然看到这篇文章的人。在你的情况下，我想这确实是miniconda和系统python分发之间的冲突。
