Figures not extracted even with ExtractOutputPreprocessor

[parthi2929]

Hi

I am trying to export html with base64 images as separate files (to import to wordpress blog). Below is code I am trying as per suggestion here. The 'ouptuts' dictionary is simply empty with no png files.

# from urllib.request import urlopen
from nbconvert import HTMLExporter
from traitlets.config import Config
import nbformat

# Load file
contentString = open('test.ipynb').read()
jake_notebook = nbformat.reads(contentString, as_version=4)


# Default HTML exporter
html_exporter = HTMLExporter()
html_exporter.template_file = 'basic'
# print("Resources:", resources.keys())
# print("Metadata:", resources['metadata'].keys())
# print("Inlining:", resources['inlining'].keys())
# print("Extension:", resources['output_extension'])

# HTML exporter with figures
c = Config()
c.HTMLExporter.preprocessors = ['nbconvert.preprocessors.ExtractOutputPreprocessor']
html_exporter_with_figs = HTMLExporter(config=c)
html_exporter_with_figs.preprocessors


(_, resources)          = html_exporter.from_notebook_node(jake_notebook)
(_, resources_with_fig) = html_exporter_with_figs.from_notebook_node(jake_notebook)

print("resources without figures:")
print(sorted(resources.keys()))

print("\nresources with extracted figures (notice that there's one more field called 'outputs'):")
print(sorted(resources_with_fig.keys()))

print("\nthe actual figures are:")
print(sorted(resources_with_fig['outputs'].keys()))

Kindly help. Here is the gist (please check raw, as gist does not seem to decode base64 inline image)

ExtractOutputPreprocessor only extracts outputs, not attachments in markdown cells. I think someone was investigating extracting attachments in another issue thread.

This should now be doable with #1978
