我在我的 anaconda 环境中从 matplotlib 包中导入 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)

导入 matplotlib (import 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，有人知道我为什么会收到此错误吗？
