Package: python3-taskflow
Version: 3.1.0-3
Severity: important

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

I was trying to set up openstack/cinder for self-teaching purpose from buster 
Debian packages.

I got an error when trying to create a cinder volume from openstack web 
interface. This is the relevant extract from cinder-api logs:

1d035f8b786d - default default] Caught error: <class 'AttributeError'>

Taskflow code calls function nodes_iter(). 
This function has been removed from networkx since version 2.0 (source: 
migration guide from 1.X to 2.0 
https://networkx.github.io/documentation/stable/release/migration_guide_from_1.x_to_2.0.html)

Unfortunately, Buster only ships version 2.1-1 of networkx.
