Sure, Your comment made me think about the IPython aspect. I found that the issue was due to the usage of both the inline=True and svg format at the same time. If I use inline=False, the svg export works fine. Thanks, Best, Alex On Fri, Mar 9, 2018 at 3:38 PM, Tiago de Paula Peixoto <tiago@skewed.de> wrote:

Hi,

I cannot export graphs to svg files with graph_draw(). Exporting to pdf or png works fine. With svg, it raises an ExpatError:

File "/home/alex/graphtoolenv/lib/python3.6/site-packages/graph_ tool/draw/cairo_draw.py", line 1197, in graph_draw img = IPython.display.SVG(data=out.getvalue())

File "/home/alex/graphtoolenv/lib/python3.6/site-packages/ IPython/core/display.py", line 599, in __init__ self.data = data

File "/home/alex/graphtoolenv/lib/python3.6/site-packages/ IPython/core/display.py", line 717, in data x = minidom.parseString(svg)

File "/usr/lib64/python3.6/xml/dom/minidom.py", line 1968, in parseString return expatbuilder.parseString(string)

File "/usr/lib64/python3.6/xml/dom/expatbuilder.py", line 925, in parseString return builder.parseString(string)

File "/usr/lib64/python3.6/xml/dom/expatbuilder.py", line 223, in parseString parser.Parse(string, True)

ExpatError: no element found: line 1, column 0

Any idea of the reason why it fails?

Without a minimal and self-contained example that shows the problem is impossible to say anything. Just an error message without context is unhelpful. (E.g. from the error message I can infer that you are using a Python notebook. This is important information that you failed to mention).

Best, Tiago
