python - 无法在 ipython 中导入 Tensorflow

Question

我的 macbook pro Yosemite 上有 TensorFlow 版本 1.0.0 非 GPU 版本。它安装在 virtualenv 中，我有 python 2.7。我有六个版本1.4.1。当我在命令行上执行 python 并导入 6 时，它工作正常。但是当我输入“ipython”并导入tensorflow时，我看到这个错误:

我尝试升级 6，但仍然看到版本 1.4.1。六是问题所在吗？如果不是的话是什么？

Answer 1

似乎有很多事情纠缠在一起。我将 Anaconda2 与 six==1.10.0、tensorflow==1.0.0 和 Python 2.7.12 一起使用。一个快速实验是安装 Anaconda2(即使用 python2.7)，然后安装 pip install TF 和其他依赖项并尝试一下。

Anaconda 安装是独立的，因此您不会受到其他系统范围问题的影响。我只是通过运行 /Users/myusername/anaconda2/bin/ipython

来完成的
