Example that fails to execute#

This example demonstrates a code block that raises an error and how any code blocks that follow are not executed.

When scripts fail, their gallery thumbnail is replaced with the broken image stamp. This allows easy identification in the gallery display.

You will also get the python traceback of the failed code block.

19 import numpy as np
20 import matplotlib.pyplot as plt
22 plt.pcolormesh(np.random.randn(100, 100))
plot raise
<matplotlib.collections.QuadMesh object at 0x7fad85d9b220>

This next block will raise a NameError

27 iae
Traceback (most recent call last):
  File "/home/circleci/project/examples/no_output/plot_raise.py", line 27, in <module>
NameError: name 'iae' is not defined

Sphinx gallery will stop executing the remaining code blocks after the exception has occurred in the example script. Nevertheless the html will still render all the example annotated text and code blocks, but no output will be shown.

Here is another error raising block but will not be executed

38 plt.plot('Strings are not a valid argument for the plot function')

Total running time of the script: ( 0 minutes 1.000 seconds)

Estimated memory usage: 460 MB
