问题描述
我无法在任何 Google Colabs 笔记本.
例如，即使是简单的Bokeh示例，也可以直接从 HoloViews简介
For example even the simple Bokeh example right out fo the HoloViews introduction
points = hv.Points(np.random.randn(500,2))
points.hist(num_bins=51, dimension=['x','y'])
无法显示任何内容，没有报告任何错误，而相同的代码(以及来自HoloViews的所有示例代码)在本地Jupyter笔记本中正常工作.
fails to show anything, without any error being reported, while the same code (and all example code from HoloViews) works fine in local Jupyter notebooks.
如果我在本地下载Colabs笔记本并打开它，则会看到以下内容，在Colabs中什么也没说:
If I download the Colabs notebook locally and open it, I see the following where I say nothing for output in Colabs:
如何使Bokeh HoloViews显示在Google Colabs笔记本中?
How do I get Bokeh HoloViews to display in Google Colabs notebooks?
推荐答案
请参见 https://github .com/pyviz/holoviews/issues/3551 . Colaboratory在处理笔记本电脑方面有一些严重的限制，现在您必须执行一次:
See https://github.com/pyviz/holoviews/issues/3551 . Colaboratory has some serious limitations on how it handles notebooks, and for now you have to do this once:
import os, holoviews as hv
os.environ['HV_DOC_HTML'] = 'true'
然后，对于其中包含绘图的每个单元格，必须重新加载JS:
Then for every single cell with a plot in it you have to re-load the JS:
hv.extension('bokeh')
hv.Curve([1, 2, 3])
如果Google可以解决此问题，那将是非常好的，因为我认为这是行不通的.
It would be great if Google could fix that, as it's unworkable in my opinion.
