Uncertainty simulation: Error while computing samples using LHS

Hello,

I wanted to run an uncertainty simulation with 60 minute and 30 minute data but keep receiving the same error message:

"An error ocurred while computing the samples using LHS:
Could not read output file var/folders/sy/1qs4snwj1g5ft5zzz14gzwzr0000gn/T/SAMLSH.LSP "

I am running the SAM version 2022.11.21, 64bit.
SSC version 280: OS X 64 bit GNU/C++
wxWidgets 3.2.0 on macOS Monterrey version 12.6.6 (Build 21G646)

I have been able to run the uncertainty analysis with no problem on other computer with the very same data files.

Thanks!

Heduardo

 

Heduardo,

Thanks for reporting this issue. We have duplicated your failing results on MacOS.

Please track progress on this issue at  github.com/NREL/SAM/issues/1417

 

I have come across the same error while running an uncertainty model:"An error occurred while computing the samples using LHS:Could not read output file /var/folders/yg/t3lyshyd56zdhzznvf6d18mssz8fgv/T/SAMLHS.LSP"I am running on a Mac, MacBook Pro, M1 chip, OS 13.6.6Version 2023.12.17, 64 bit, updated to revision 1SSC Version 290: OS X 64 bit GNU/C Mar 7 2024 03:31:21I have gotten this to occur across multiple weather files, but I am attaching one. 

   

Hi Simon,

Thank you for letting us know about this.

The Uncertainty simulations don't work on Mac and Linux versions of SAM:

github.com/NREL/SAM/issues/1417

github.com/NREL/SAM/pull/1504

Unfortunately, we don't have a solution for this yet, but are working to find one.

Best regards,
Paul.

Ok, this makes sense now. I didn't understand the github timeline.

Appreciate the support and I'm excited about this feature when a solution is discovered.
