BPMN Support missing? #189

Closed fabigr8 closed 3 years ago

fabigr8 commented 3 years ago

Hi everybody,

i tried to import and visualize a BPMN charts based on this example: http://pm4py.pads.rwth-aachen.de/bpmn-2-0-management/

Steps: xml import --> layout --> visualize via "bpmn_vis_factory.view"

but already the import is crushing (see console output below). After researching the problem, i found that the package pm4pybpmn is only available in PIP but i could not found the development branch here. And in the pm4py-core the visualization of BPMN isn't there anymore, i think? did you change the project / dependencies or revoke the bpmn visualization support?

i also reffer to https://github.com/pm4py/pm4py-core/issues/60

i achieved to fix it manually, that could be done by changing "/pm4pybpmn/visualization/bpmn/versions/frequency.py" in line 11 from " from pm4py.visualization.petrinet.versions import token_decoration" to "from pm4py.visualization.petrinet.variants import token_decoration_frequency" and changing "/pm4pybpmn/visualization/bpmn/versions/performance.py" from "from pm4py.visualization.petrinet.versions import token_decoration" to "from pm4py.visualization.petrinet.variants import token_decoration_performance"

is there a branch to push these changes? or did i just oversee the bpmn visualization support? maybe someone can help me with this.

cheers. F.

Dear fabigr8,

We dropped the package "pm4pybpmn" to go for a standalone support for BPMN diagrams.

You can find the documentation on https://pm4py.fit.fraunhofer.de/documentation

A visualizer for BPMN diagrams will be probably there in the next release of PM4Py

Has the visualiser been released yet?

thanks

Dear Erinaceida,

You can visualize a BPMN diagram inside PM4Py by doing:

import pm4py pm4py.view_bpmn(bpmn_graph_object)

Thanks! This isn't in the documentation. Where can I find a complete description of all functions in pm4py? regards
