如何在 Jupyter Notebook 中显示文件中的图像? [英] How can I display an image from a file in Jupyter Notebook?

问题描述

我想使用 IPython notebook 作为交互式分析我正在制作的一些基因组图表的一种方式使用 Biopython 的 GenomeDiagram 模块.虽然有大量关于如何使用 matplotlib 在 IPython notebook 中获得内联图形的文档，但 GenomeDiagram 使用了 ReportLab 工具包，我认为 IPython 中的内嵌图形不支持该工具包.

I would like to use an IPython notebook as a way to interactively analyze some genome charts I am making with Biopython's GenomeDiagram module. While there is extensive documentation on how to use matplotlib to get graphs inline in IPython notebook, GenomeDiagram uses the ReportLab toolkit which I don't think is supported for inline graphing in IPython.

然而，我在想，解决这个问题的一种方法是将绘图/基因组图写到一个文件中，然后内联打开图像，这将得到与以下内容相同的结果:

I was thinking, however, that a way around this would be to write out the plot/genome diagram to a file and then open the image inline which would have the same result with something like this:

gd_diagram.write("test.png", "PNG")
display(file="test.png")

但是，我不知道如何做到这一点 - 或者不知道是否可行.那么有谁知道图像是否可以在 IPython 中打开/显示?

However, I can't figure out how to do this - or know if it's possible. So does anyone know if images can be opened/displayed in IPython?

from IPython.display import Image
Image(filename='test.png')
