Anaconda：matplotlib PdfPages 导入错误

Question

我在 anaconda 环境中从 matplotlib 包导入 PdfPages 函数时遇到问题。我收到以下错误：

Python 2.7.13 |Anaconda 4.4.0 (64-bit)| (default, Dec 20 2016, 23:09:15)

AttributeError: 'module' object has no attribute 'glob'

虽然导入 matplotlib（导入 matplotlib）工作正常。我在使用 Anaconda (/.../.virtualenv/h5_to_histo_env/)

创建的虚拟环境中运行 python

根据 conda-V，我的版本是 'conda 4.3.16'，我的 matplotlib 版本是 2.0.2 ('np112py27_0')。我的 Anaconda 环境也是最新的，有人知道为什么我会收到这个错误吗？

Answer 1

更新：重新安装虚拟 anaconda 环境并在开始时使用 conda create 命令指定所需的包（而不是在虚拟环境已经创建之后）以某种方式修复了它！
