Error on test run: AttributeError from 'AbstractModel'

[Mathieu Saurat]

Hello,

I am new to Temoa. I am running Ubuntu 12.04 on a virtual machine (Parallels) on Mac OS 10.8.5. I have Python 2.7.11, Anaconda 2.4.1 (64-bit), Pyomo 4.2.10784 (CPython 2.7.11 on Linux 3.2.0-94-generic), GLPK, and the temoa model (temoa.py and example_data_sets downloaded from the website, not GitHub) installed. When I test run Temoa with any of the data files from example_data_sets, I get the following:

parallels@parallels-Parallels-Virtual-Platform:~/Python/TEMOA$ python temoa.py example_data_sets/temoa_island.dat
Notice: Using the GLPK solver interface.

AttributeError: 'AbstractModel' object has no attribute 'update_results'

Any idea on what may have happened and what I need to change to be able to run Temoa?

Best,
Mathieu

In case somebody else runs into the same problem, here is the fix that worked for me: using the most updated code from github.
The code can be downloaded directly as a zip file from https://github.com/TemoaProject/temoa (click the "Download ZIP" button on the righthand side) or by using git clone. How to run the code is then explained in the READ_ME file.

Hi Mathieu,

Glad you were able to get it working. Just to confirm, the zip file available through temoaproject.org is currently out of date. For users who would like the most updated code but don't want to install Git and clone, you can go to our github page (https://github.com/TemoaProject/temoa) and click the "Download ZIP" button on the righthand side.

In the meantime, we'll work to get the website version updated.

Thanks,
Joe

Hi Hayford,

The attached error looks like it is related to pyomo. Try running "pyomo solve" from the command line. It should return information on how to run a model. If that command returns an error, then there is a more basic problem with the installation.

Also, just a warning that the latest version of pyomo broke the Temoa code. We will be updating the code soon, but in the meantime, I suggest running pyomo 4.2. (I'm currently running 4.2.10784.)

Best,

Joe

Hello all, 

Mathieu thanks for the tips on this issue. I am new to PYOMO, and I have just run into this problem (see attached screenshot). However, I am a PC user. Any chance anyone can help solve this issue.

Thanks

Hello,

I got some difficulties to run the model with command line. It seems to be ok with the web interface. I am using pyomo 5.3 and it doesnt work. What should I do ?

Hello,

I am using pyomo 5.3 I used the README.txt file instructions to run the model and didn't succeed. It seems to be ok online with the web interface. What should I do to have the model run with command line ?

Best,

The latest version of Pyomo broke our model. I hope to resolve this soon. If you downgrade to Pyomo 4.2, it should work fine. I'm currently running Pyomo 4.2.10784 and Temoa works fine. Let me know if that solves the problem.

Best,
Joe
