Bug#902366: missing pydot dependency ( there is only in recommends )

[Michal Arbet]

Package: python3-networkx
Version: 2.1-1

Package: python-networkx
Version: 2.1-1

Dear Maintainer,

In networkx python packages is missing dependency for install python-pydot
( python3-pydot for python3 package version )

Here you can see the diff between 1.11 and 2.1 version grepping where is
pydot imported
Instead of pydot was used pydotplus package in previous versions of
networkx .


git diff networkx-1.11rc2 networkx-2.1 | grep pydot | grep import

   No longer import nx_agraph and nx_pydot into the top-level namespace.
+>>> from networkx.drawing.nx_pydot import write_dot
+        import pydot
+        from networkx.drawing.nx_pydot import graphviz_layout
-            import pydotplus
-            from networkx.drawing.nx_pydot import graphviz_layout
-        import pydotplus
+        import pydot
         from networkx.drawing.nx_pydot import graphviz_layout
-        import pydotplus
+        import pydot
         from networkx.drawing.nx_pydot import graphviz_layout
+        import pydot
+        from networkx.drawing.nx_pydot import graphviz_layout
-            import pydotplus
-            from networkx.drawing.nx_pydot import graphviz_layout
-            import pydotplus
-            from networkx.drawing.nx_pydot import graphviz_layout
-        import pydotplus
+        import pydot
         from networkx.drawing.nx_pydot import write_dot
-    import pydotplus
+    pydot = _import_pydot()
-    import pydotplus
+    pydot = _import_pydot()
-    import pydotplus
+    pydot = _import_pydot()
+def _import_pydot():
+        If the `pydot` module is either unimportable _or_ importable but of
+    import pydot
-        import pydotplus
+        return _import_pydot()
-            import pydotplus


Pydot is included only in recommends...

Please, could you fix it ?



Thanks,
