holoview.extension('bokeh') - 无法导入扩展
holoview.extension('bokeh') - cannot import extension
我想测试 HoloViews，但遇到了几个错误。
我安装了两次（建议的不同设置 here）。我使用了 !pip install holoviews 和 !pip install 'holoviews[recommended]'.
安装时我得到：
Requirement already satisfied: holoviews in /usr/local/lib/python2.7/dist-packages
Requirement already satisfied: param>=1.3.2 in /usr/local/lib/python2.7/dist-packages (from holoviews)
Requirement already satisfied: numpy>=1.0 in /usr/local/lib/python2.7/dist-packages (from holoviews)

This may cause the server to present an incorrect TLS certificate, which can cause validation failures. You can upgrade to a newer version of Python to solve this.

所以，我可以导入 HoloViews（它作为版本 1.6.2 在已安装包列表中），但是 holoviews.extension('bokeh') 不起作用。所以我不能使用它。
我正在使用
- Python 2.7.6
- Jupyter 笔记本 5.1.0
- 散景 0.12.9
- 麻木 1.13.1
- Pandas 0.20.3
对于我做错了什么或我可以做些什么来解决这个问题的任何提示，我将不胜感激。我不太熟悉安装软件包。如果您需要更多信息，请告诉我。我花了几个小时 searching/googling 没有结果的答案。
非常感谢。
包含 pip install bokeh，我发现 pip install holoviews[recommended] 在干净的 Python 2 环境中正常工作。这将安装最新的 HoloViews 版本 1.9.2。
看起来您的系统上可能安装了较旧的 holoviews，因此我建议您在干净的 Python 2 环境中重试。或者，尝试通过 运行ning pip install holoviews[recommended]==1.9.2 固定版本。请注意，您还需要散景版本 0.12.13，因此请确保 运行 pip install bokeh==0.12.13。
