Hi everyone, When I was learning to use the ROOT tool to optimize the example data, I entered it without any errors or warnings, but unfortunately, I got an error after clicking “run”: Key Error encountered: “combined_factors” InVEST-ROOT-log-2024-06-19–21_13_50.txt (1.9 KB) I’m not sure what th…

Hello @Hannah24523 , Thanks for including your logfile! Based on the source code from this version of ROOT, it appears that you will need to have ROOT do its preprocessing if you also want ROOT to do its optimization. Please let us know if you have any further questions! James

Hi Hannah, even though it’s not clear on the interface or in the documentation, you need to run the preprocessing step first and then the optimization. If you try to do both at the same time, it will fail.

Hello James, Thank you for your reply, I’ve done the preprocessing step using ROOT and then optimized, but unfortunately still encountering the same error. InVEST-ROOT-log-2024-06-21–09_56_40.txt (7.1 KB) InVEST-ROOT-log-2024-06-21–09_56_56.txt (1.9 KB) [image]

Hi Nadine, Thanks for the suggestion, but I didn’t use ROOT to prep and optimize at the same time, so there may be other reasons to consider. If both preprocessing and optimization are checked, ROOT gives back the error: UFuncTypeError encountered: ufunc ‘multiply’ did not contain a loop with sig…

Sorry, either I’m not understanding your not explaining it well. You cannot run ROOT with both boxes checked. You need to first run the top preprocessing section, then uncheck it and run the optimization session. Is that what you’re doing?

Can you also make sure all of of the paths have the same slash direction. Navigate to the folders to ensure they are correct. I see your version is different than mine, so tomorrow I’ll send you my version of ROOT.

Hi Nadine, I did the optimization after successfully preprocessing the data first, without checking both checkboxes.I’m still getting the same error so it’s a bit of a struggle. Thank you for your prompt response.

Hi Nadine, It would be great if you could share the ROOT you used, thanks a lot! Thank you for your advice and support and I look forward to hearing from you again! -Hannah

Hi Hannah, I’m not at my computer now, so will share my version tomorrow. Meanwhile, if you want to zip up your tables and inputs, I can troubleshoot and try to run on mine.

Hannah, here’s a link for you to download my version of root. Please let me know if that works. root64_Mar2019.zip - Google Drive
