renview stuck

[raoulpetite]

Hi, I'm investigating renview to see if it can help in my research work. Unfortunately, it looks like it remains stuck somewhere after the creation of the result directory (see the message below obtained after a Crtl C). I tried several things without any success. Let me add that I tested graphiz with small examples from its manual and they worked fine.
So if if someone can help, I ll be grateful.

Hi Raoul,

It seems that the issue might be because of the check_call renview uses to generate svg files in Windows. In ubuntu, replacing that line with

dot -Tsvg f.name -o filename_svg

should work fine.

Can you comment out the check_call in the GraphGenerator/init.py and use the above statements to generate the svg files?

Sir,
First of all, I thank you for the time you spent to answer my post.
The dot statement you recommended me to use in init.py lead to the following error :
dot -Tsvg f.name -o filename_svg
^
SyntaxError: invalid syntax

Nevertheless, your description of the error helped me out to find a fix. I commented out the check_call lines and replace it by the 2 following lines for each check_call.
(graph,) = pydot.graph_from_dot_file(f.name)
graph.write_svg(filename_svg)

It required also to import pydot. It looks like this worked just fine as I have now all the svg files in the ammonia example directory.
Regards

Thanks, Raoul for letting us know that you were able to find a workaround.

dot -Tsvg f.name -o filename_svg

works if Graphviz has been added to the system path. dot is a built-in command in Graphviz.

pydot is doing the same thing where pydot is a python package for Graphviz.

I will include instructions for people working on OS other than windows.
