Output in cell disappears immediately after executing in google colab notebook

[SaurabhThakre]

from matplotlib import pyplot as plt

x = [5, 2, 9, 4, 7]
y = [10, 5, 8, 4, 2]
plt.plot(x,y)
plt.show()

When I try to execute the above code in google colab notebook, its output appears for milliseconds and disappears immediately and does not remains. This behaviour only occurs when trying to plot the graph using matplotlib. But this does not happen when I use a print statement, the output does not disappear like the graph for the above plot.

I have recorded and added this gif, which shows the above-described problem in my colab.

Thanks for the report!

I can't seem to reproduce this, which makes me think one of two things may be in play:

• previous code you've run in this notebook causing trouble; can you repro if you run just that code in a fresh notebook?
• a chrome extension causing trouble; can you repro in an incognito window?

I have removed all my extensions from chrome and now it shows the output properly.
Some extension was causing this problem.
Thanks @craigcitro

If you are able to narrow down which extension caused the issue please let us know in case others run into this later. Thanks!

It was Urban VPN extension.
