Hello,
I am running Sagemath 7.3 on Linux. I would like to export a graph using the export function of the graph, but I get the error
ImportError: No module named pydotplus
The python module pydotplus was already installed with pip install pydotplus
I cannot find any help regarding this issue. Any suggestion?
Thank you in advance for your help
If you want to install pydotplus and use it from Sage, you have to install it withind Sage's virtual environment (which is disjoint from your system's Python install): for this, you have to type:
sage -pip install pydotplusBy the way, let me suggest to upgrade your Sage to a more recent version.
Many Thanks: it worked out. You're right, I need to upgrade sage on my laptop...
Great, couuld you please provide an example of use of this package in the context of Sage, maybe we could include it somehow.
If G is a graph then G.export_to_file("filname", "dot") will export the graph in the DOT Graph Description Language. This function calls pydotplus.
Is that the kind of example you were asking for?

pydotplusbeing part of Sage, or at least some of its distros (i am considering installing it within Sage Debian Live).
