[FIXED] How to suppress graphviz warnings in Python 3?

Issue

I'm using the graphviz module to render a network of nodes and links.

I use small circles as node's shape, so the labels are intentionally bigger than the nodes.

As a consequence, I get the following warning:

"Warning: node 'wave', graph 'N' size too small for label"

'Wave' is just an example of a node's label.

I get lots of this warnings because of the high quantity of nodes (screencapture).

So, my question is: How can I suppress warnings like those?

The graphviz command I'm using is:

n.view()  # n is my digraph

I have already tried the suggestions from:

How to suppress a third-party warning using warnings.filterwarnings

How to redirect python warnings to a custom stream?

But nothing so far. Thanks in advance.

Solution

Try Eli Bendersky's excellent page: Redirecting all kinds of stdout in Python

After replacing stdout with stderr, Eli's solution worked on graphviz for me.
