PROBLEM WITH PYOMO.CORE

[Amedeo Testori]

Hello,

I'm facing some problems with the creation of the environment conda and some packages are not downloaded automatically. More precisely even if I gave pyomo.core in C:\Users\amedeo.testori\anaconda3\envs\temoa-py3\lib\site-packages\pyomo it does not find it. Please not I'm running temoa_utopia so the code should not provide error by itself.

I report below the error message:

Hi Amedeo,

Sorry to hear you're having trouble. A few follow-up questions:

1. What operating system are you using?

2. What error is given when you install the environment?

3. Have you activated the environment once you've created it? The command is:

$ conda activate temoa-py3 (or whatever you named it)

I always receive the "Unable to find 'pyomo.core'" error when I don't have the Temoa environment activated.

Best,

Joe

[Amedeo Testori]

Hi Joe, thanks for your prompt reply!

1. I'm using Windows 10 Home

2. When I install the environment is not giving any error, but I cannot visualize the environment between the ones avaiable in  conda.
3.I did activate the environment once created it.

I leave I attached a screenshot from the Python Interpreter Setting in Pycharm

Thanks

Hi Amedeo,

From the Anaconda shell, what happens when you try the following?

$ pyomo solve --help

You should be provided with a description of how to run pyomo. If that doesn't work, it means your system can't find pyomo. In that case, check the pyomo documentation for more help.  If it does work, try solving the model from the anaconda prompt as follows:

$ pyomo solve --solver=cplex temoa_model/temoa_model.py data_files/utopia-15.dat

Let me know what you find.

Best,

Joe

[Amedeo Testori]

Hello,

writing  $ pyomo solve --help it follow:

The same error is given when I digit $ pyomo solve --solver=cplex temoa_model/temoa_model.py data_files/utopia-15.dat in the

anaconda prompt (temoa-py3). 

Does it sounds something to you?

Thanks again

Hi Amedeo,

This is definitely an issue with the pyomo installation, since it throws the same error even when you try to invoke the help function. You may want to try reinstalling the environment. I suspect it may have to do with pyutilib, which you mentioned in a previous email that you had to install manually. Your versions of pyomo and pyutilb may be out of sync. As noted in the environment file, Temoa requires pyomo v5.5 and pyutilib v5.8.

Best,

Joe

Hi!

I have installed the packages passing by the comand:

pip install Pyomo==5.5.0 

pip install PyUtilib==5.8.0

Now the error launching temoa is:

I don't know if it represents any kind of improvement, it seems so to me.

Wait for your opinion.

Hi Amedeo,

Based on the error, looks like your trying to invoke pysp to do a stochastic run. Can you just try a single run with temoa_utopia.sqlite to see if the installation works, using the config file setup as-is from Github?

Best,

Joe

[Amedeo Testori]

Hi Joe,

I tried to run temoa_utopia.sqlite with config_sample from Github (it seems to be the same I was running) but the error is always the same:

What do you think about?

Thanks

Hi Amedeo,

Can you try the pyomo solve --help command again? I suspect this is an issue with pyomo and not Temoa. If the help command works, then try to solve one of the simple problems in the pyomo gallery. If pyomo passes both those tests, then we can further debug Temoa. If those basic tests fail, then I would recommend a clean install of the Temoa environment or use the Pyomo stack exchange forum, which is linked near the bottom of this page.

Best,

Joe

I think this means the test have been failed ! So you suggest to pass throught the pyomo forum.

You suggested to go for a clean install of Temoa, what do you mean for that?

Thanks

Hi Amedeo,

There's something wrong with your pyomo installation, which was installed as part of the Temoa environment. To try reinstalling, first deactivate the Temoa environment:

$ conda deactivate temoa-py3

And then uninstall it:

$ conda remove --name temoa-py3 --all

Then repeat the steps outlined here to re-install the environment, which includes the version of pyomo known to work with Temoa.

If that doesn't work, then perhaps try the Pyomo forum to see if they can help.

Best,

Joe

[Amedeo Testori]

Hi joe, 

While trying to execute this command 

$ conda remove --name temoa-py3 --all

I run into this error (I leave a screenshot attached):

-Invalid Python SDK-
Cannot set up a python SDK at Python 3.7 (temoa-py3 )(C:\Users\amedeo.testori\anaconda3\envs\temoa-py3\python.exe).
The SDK seems invalid.

You know how to solve it? Cause If I press OK it gives me it again after a few seconds. So I got stucked.

Thanks 

Amedeo Testori

Hi Amedeo,

Apologies for the slow response. I've not run into this issue before, so not sure how to resolve. It may have to do with your use of PyCharm, which I have not used before. For example, here is a similar issue being discussed on StackOverflow. Perhaps try running the model from the command line rather than through PyCharm to see if it works.

Best,

Joe
