get_out_degrees function issue


I'm trying to use the function "get_out_degrees", but I get following error:

AttributeError: 'Graph' object has no attribute 'get_out_degrees'

The graph I generated is a directed graph:
<Graph object, directed, with 396 vertices and 10042 edges at

The gt version is the 2.18 (Ubuntu Trusty):
'2.18 (commit 37996a0a, Thu Jul 21 17:56:14 2016 +0200)'

Any idea of what I'm doing wrong?

Thanks a lot!

Yes, this is a very old version, which does not include this function. The
current version is 2.26, which does.
