New submission from John Brearley <[email protected]>:
I have successfully installed Graphviz tool from http://graphviz.org, updated
my PATH variable appropriately and can generate .PNG files using Python module
Graphviz with WinPython 3.6.1. However, I cannot get anywhere using the pydot
V1.2.3 module in the same environment.
The online help suggests that there there are write & write_png members but I
can find no trace of them. My sample script is attached. The error I get is:
Traceback (most recent call last):
File "ML_ex2.py", line 109, in <module>
graph.write(path=out_fn, format="png")
AttributeError: 'list' object has no attribute 'write'
