Visualization in IPython

[msildatke]

Hey,

this is my first time working with GitHub, so i am not really sure how to communicate the best way:

Using IPython (in Spyder) i was not able to visualize the diagrams wihle testing the following example:

from pm4py.algo.discovery.alpha import factory as alpha_miner from pm4py.objects.log.importer.xes import factory as xes_importer from pm4py.visualization.petrinet import factory as vis_factory

log = xes_importer.import_log('') # i of course added the correct path net, initial_marking, final_marking = alpha_miner.apply(log) gviz = vis_factory.apply(net, initial_marking, finalmarking) vis_factory.view(gviz)_

After doing some research i solved the problem by editing the gview.py in pm4py-source/pm4py/visualization/common/ as follows:

def view(gviz): """ View the diagram

Parameters
-----------
gviz
    GraphViz diagram
"""
is_ipynb = False

try:
    get_ipython()
    is_ipynb = True
except NameError:
    # we are not inside Jupyter, do nothing
    pass

if is_ipynb:
    from IPython.display import Image

added / edited Lines

    image = Image(open(gviz.render(), "rb").read())
    from IPython.display import display
    return display(image)
else:
    return gviz.view()

the added commands lead to the correct visualization in IPython-console.
