Subject: Re: [Qgis-user] question regarding linking Algorithms in Graphical Modeler
that " [Errno 9] Bad file descriptor" is usually caused by a print statement trying to print to the console while the console is closed. Opening the Python console should let you run the model. Sounds to me like a debug line that was committed and not removed later
Anyway, it should be fixed in the current version, but i will check and remove any debug line in case there are still in the code
Hope this helps

Hi Carl,
I have the same problem for different modells made with QGIS 2.2 and QGIS 2.4.
I think it is a problem with the processing plugin and I hope it will be solved with QGIS 2.6
<Hi, I'm running QGIS 2.4.0-Chugiak on a Windows & machine, and I'm new to QGIS.
<I'm trying run a model that has three algorithms, two of which are run in "parallel" and a third that <uses the outputs from form the first two. I specified that that third The first algorithm runs fine but <when it gets to the second it bombs with the message:
< C:\PROGRA~1\QGISCH~1\bin>exit
< Converting outputs
< Outputs: outfile =E:/temp/PreNBR7.tif
< OK. Execution took 49.503 ms (1 outputs).
< Prepare algorithm 1: r.mapcalculator - Calculate new raster map from a r.mapcalc <expression.
< [Errno 9] Bad file descriptor See log for more details
<The three pieces work fine when broken into separate models but I would like to have the whole <thing run in one go..
<I exported to a script (below) and have attached the model.
