error with running the model

[giulia pezzin]

Hi everyone,

I'm trying to run the model but it gives me this error: 

Traceback (most recent call last):

AttributeError: 'SolverFactoryClass' object has no attribute 'services'

Since now the errors I had were related to some missing packages so I solved them by installing what was needed. But this one seems different and I'm not finding any solution online.

Thank you in advance.

Did you install the Temoa environment using the environment file, as explained here? If not, you my be running into version issues with some of the required software elements.

Best,

Joe

Thank you for your kind answer. 

Yes I've already had the environment file on my Mac. I've tried anyway to remove and create again the conda environment following the steps in the video but it gave me the same error.

I tried to install an older version of pyutilib and now the error has changed (see below), but I'm truly going with guesses right now so I'm not sure if I have made improvements or instead worsened the situation.

Thank you again for your time.

Hi Giulia,

Unfortunately, I'm not sure what the issue may be. Looking at the stack trace, are you trying to import data from a spreadsheet? What happens when you simply run:

$ pyomo solve --help

If it works, what happens when you run the following from the temoa directory:

$ pyomo solve --solver=<solver> temoa_model/temoa_model.py data_files/utopia-15.py

Let me know the output from these commands, and we can take it from there. If the first command doesn't work, you may need to ask on the pyomo forum.

Best,

Joe

Thank you very much for all the help.

I've tried to contact the pyomo forum since the first command does not work and it seems then to be a problem related to that package. 

Thank you again  and have a good day. 

Best regards, 

Giulia

Giulia, finally how did you solved? I'm getting the same problem after updating pyomo from 5.5 to 6.2

[Temoa Project]

Hi Daniele,

Temoa currently only runs on Pyomo version 5.5, as noted in the environment file. See Joe's earlier email in this thread about installing the Temoa environment using the environment.yml file. 

I hope this helps. 

Best,

Aranya

Hello all, 

I'm checking in on this post since I am experiencing issues running a model on a Windows 10 machine.

1) Temoa doesn't seem to accept glpk as a solver when CPLEX is available on my machine (i.e. --solver=glpk does not work)

2) When using Pyomo 5.5 and CPLEX (version 20.1) I get the following error:

objective_value = (tokens[0].split('=')[1].strip()).lstrip("\"").rstrip("\"")

IndexError: list index out of range

3) This post from early last year suggests updating Pyomo solves the issue. Yet, as Daniele and Aranya found, doing so introduces a new issue.

Any guidance in this matter is appreciated. 

Thanks, 

Sam

Hi Sam,

Could you check what version of glpk you have currently installed ("conda list")?

We just tested temoa_utopia on a Windows machine with glpk (version 4.65) that was installed using the temoa environment.yml file and that seemed to work. 

Best,

Aranya
