I want to insert the plot I created into the power point with insert_picture().
I searched from online and found info here.

I create a simple figure as below: 

fig, ax = plt.subplots(2,1, sharex=True, sharey=True)

And I use python-pptx to create a power point. 

graph_slide_layout = prs.slide_layouts[0]
slide = prs.slides.add_slide(graph_slide_layout)
title = slide.shapes.title
title.text = "Test"
placeholder = slide.placeholders[1]
pic = placeholder.insert_picture(fig)
prs.save('Desktop\test.pptx')

However, I got an error: 

AttributeError: 'SlidePlaceholder' object has no attribute 'insert_picture'

There is a note I found here. 

Note
A reference to a picture placeholder becomes invalid after its insert_picture() method is called. 
This is because the process of inserting a picture replaces the original p:sp XML element with a new p:pic element containing the picture. 
Any attempt to use the original placeholder reference after the call will raise AttributeError. 
The new placeholder is the return value of the insert_picture() call and may also be obtained from the placeholders collection using the same idx key.

After that, I changed the code to: 

graph_slide_layout = prs.slide_layouts[8]
slide = prs.slides.add_slide(graph_slide_layout)
title = slide.shapes.title
title.text = "Test"
placeholder = slide.placeholders[1]
pic = placeholder.insert_picture(fig)
prs.save('Desktop\test.pptx')

placeholder.name
'Picture Placeholder 2'
placeholder.placeholder_format.type
18

I got another error: 

AttributeError: 'Figure' object has no attribute 'seek'

Any idea?

I solved it.
You should save the figure first and use the save plot. 

fig.save('test')

pic = placeholder.insert_picture('test.png')
