Error during testing.

[wenjingsu16]

Hi,

I followed the instruction to add the command (Pkg.add("GasPowerModels") and add JuMP Juniper Ipopt Cbc). Then I run the testing. But it gave me error as below. Thanks for your help.

This looks like a problem with Ipopt.jl. Can you try running

] test Ipopt

If that fails, perhaps try executing

] build Ipopt

[wenjingsu16]

Thanks for the quick response. The test of Ipopt failed. I tried to build Ipopt but it gave me the error below. Thanks for your help. I am new to Julia

I think this should be posted as an issue for Ipopt.jl. I'm not quite sure what the problem is, but it looks like Ipopt is not being downloaded because of an invalid SSL certificate on the website hosting the Ipopt binary.

[wenjingsu16]

OK. I found the issue in https://github.com/jump-dev/Ipopt.jl/issues/94, which says that it is solved in the master. I tried to build ipopt master. But there is a conflicts in packages as below.

I checked my package status. I do have Ipopt somehow. But when I tried to follow the tutorial on the doc page.

Try installing GasPowerModels via

] add GasPowerModels#master

and then making sure you read the development version of the documentation. The current README corresponds to this development version. You are using the README with GasPowerModels v0.1.1, which is substantially different than the current development version.

[wenjingsu16]

I followed the commands from https://github.com/lanl-ansi/GasPowerModels.jl/blob/master/docs/src/quickguide.md which should be the quick guide for the master version.

[tasseff]

This is interesting. It looks like most of the errors you've been encountering are due to a lack of common SSL certificates on your Mac. See the webpage mentioned in your error here. Let me look around and see if I can find a quick fix, but I'm also on a Mac and don't encounter these errors when installing packages.

[wenjingsu16]

Thanks a lot I really want to run the model but encountered error every line. I downloaded Julia to run this model so I am not familiar with Julia.

[tasseff]

Here is the quickest fix I can find, do you want to give it a try?

https://discourse.julialang.org/t/curl-certificate-issue-with-pkg3-on-mac/33299/7

[wenjingsu16]

Yes it worked. I downloaded homebrew and curl and appended the insecure. Now I am able to add Ipopt and GasPowerModel package. But I run into the error below when following the doc.

[tasseff]

Could you type

and post the package versions you are using? optimizer_with_attributes should be present in recent versions of JuMP.

[tasseff]

Also, try

] update

I just tagged a new release of GasPowerModels, so you don't need to add the recent version using the #master suffix.

[tasseff]

Are you running the Julia commands from the same place you are running the update command? In your update, you have a prefix in the command of (@v1.5) but not in the commands where you're trying to run GasPowerModels. It looks like you are using one instance of Julia when you upgraded and another when you actually execute the commands.

[tasseff]

My mistake, maybe that is not the case, here. I do know that if you have the recent version of JuMP (which you appear to have gotten based on your update command), JuMP.optimizer_with_attributes should definitely be defined.

[tasseff]

Could you exit and relaunch Julia, then show the contents of

[wenjingsu16]

I checked and do not think that I have another version of Julia. I am just running Julia in Mac terminal. I relaunched Julia and optimizer_with_attributes is defined now. But I ran into another error following the commands as below. Thanks so much for your help.

Ah, good find! Yes, I named the file wrong. I just pushed a change on the master branch that fixes this.

Also, make sure you're running the commands in a directory relative to these examples. If you don't have the examples, I'd recommend downloading the full source using git clone git@github.com:lanl-ansi/GasPowerModels.jl.git, running julia from within the GasPowerModels.jl directory, then executing the commands listed in the README.

Thanks. I checked the directory on the laptop and changed the name to 14belgium-ne_opf locally. Now I am able to run it.
