Error reading Vensim model (parsimonious.exceptions.IncompleteParseError) #443

Closed mak63-dev closed 4 months ago

mak63-dev commented 6 months ago

Hello,

I am not able to read a relatively complex Vensim model with eight model views.

I tried two ways and neither worked.

  1. Read the model with the default arguments:

model = pysd.read_vensim('C:\Users\...path...\model.mdl') *** TypeError: cannot unpack non-iterable NoneType object

  1. Read the model with split_views = True

model = pysd.read_vensim('C:\Users\...path...\model.mdl', split_views=True) *** parsimonious.exceptions.IncompleteParseError: Rule 'line' matched in its entirety, but it didn't consume all the text. The non-matching portion of the text begins with '|14|BU|0-0-128' (line 1, column 71).

In case 2, the text '|14|BU|0-0-128' raising the error is located toward the end of the mdl file (in text view), having to do with the sketch information generated automatically by Vensim. In particular, the line is in a block related to the eighth and last view: ... 10,73,simulator mode,194,665,68,11,8,131,0,18,-1,0,0,0,-1--1--1,0-0-0,|14|BU|0-0-128 12,74,105057302,192,632,80,20,3,60,0,0,0,0,0,0 simulator mode,0,1,1 30,75,f1303_17 - Copy0027.bmp,370,641,79,29,8,3,0,0,-1,0,0,0 12,76,34931712,812,203,221,110,3,188,0,0,1,0,0,0 ...

Thanks for any advice.
