[Mist-support] MIST Test Code Error

[Everett Mumford]

Hi Jacob,

Downgrading Matplotlib seems to have fixed the issue. Thank you for all of your help with this. I have really enjoyed using the MIST thus far and think that it will be very useful for my research.

Best regards,
Everett

Hi Everett,

It seems that the new version of Anaconda uses by default a new version of Matplotlib that breaks previous MIST code.

If you wish to use MIST 0_92_0_0 with the plot capability, you should downgrade Matplotlib. Within anaconda, you can do this by using the command:

conda install matplotlib=1.3.1

This worked on my windows machine. And is a suitable ad hoc solution if you have no code that depends on a newer matplotlib version.

Note that the plot capability is related to the MIST script CreatePlotsFromCSV.py. This script is rarely used for basic modeling and simulation, and you can use other MIST capabilities without changing the matplotlib version, as long as you ignore the plot capabilities in the CreatePlotsFromCSV.py script.

If TestCode.py does not report any other error, you should be good to proceed. Yet it is better to test this at least once by using the matplotlib downgrade command.

I will check downstream to see what was upgraded in Matplotlib to avoid this issue in the future and may provide other solutions. I also opened an issue in Github to address this.

Let me know if you encounter any other issues.

Yet hopefully, this solution will allow you to proceed for now.

          Jacob

Hi Everett,

What OS are you using? What kind of python distribution you are using and what is your matplotlib version?
If you are using anaconda, can you specify what version?

This will help isolate the issue and treat it.

The goods news are that if only the plots do not pass the test script, then you can still use the system for modeling and simulation and export data to create plots outside the system.

Hi MIST support,

I am having issues running TestCode.py. The code gets an error when it reaches the PlotGeneration scripts. The code does not always error out on the same script (e.g. I have run into errors when the code tries to run PlotGeneration5_rmjj.py, PlotGenerationoit6qb.py, etc.). I have tried uninstalling and then reinstalling the package several times.

Have you seen a similar error? And can you please provide assistance?

Thanks!

Best regards,
Everett Mumford
