After changing my workflow from legacy component to the new LBT1.2.0, I notice the Accelerad is incompatible, the error message: Solution exception:The installed Radiance is not from 2020/9/3 or later. Download and install the version of Radiance listed in the Ladybug Tools compatibility matrix 1…

Hi @miraclema , there is no incompatibility between LBT 1.2.0 and Accelerad. How did you install Accelerad on your machine? The component is trying to ensure you are using the correct version of Radiance but it might be getting it wrong by checking the release date for accelerad instead of radiance i…

I recommend using the “HB Check Versions” component to check see what Ladybug Tools thinks your installed version of Radiance is. Like you see here on the lbt-grasshopper wiki: [image] ladybug-tools/lbt-grasshopper 1.3-Verifying-Your-Installation :green_book: Collection of all Ladybug…

I think what’s going on here is that @miraclema has replaced Radiance’s rtrace command with the one that comes with Accelerad and since we use rtrace -version we get the version for Accelerad distribution instead of Radiance itself. @MingboPeng , is there a better way to get the version of Radiance …

Accelerad overrides the version from Radiance. I think the best way to fix this is @Nathaniel updates Accelerad with the new Radiance and append his Accelerad version next to original Radiance version instead of overriding it.

You can search the Accelerad version string for the Radiance version. However, there is no guarantee that Accelerad versions correspond with “official” Radiance releases. You can also use mkpmap -version, as this is not overridden by Accelerad.

[image] Nathaniel: You can also use mkpmap -version, as this is not overridden by Accelerad. Brilliant! This will be a quick and easy fix.

Thanks for the tip, @Nathaniel . I just merged a PR that will change our Honeybee Radiance version check to use mkpmap instead of rtrace, which should prevent this situation: fix(config): Grab Radiance version number from mkpmap ladybug-tools:mas…

Thank you Chris for this fix. But when I tested by updating to 1.2.2, it still tells me “The installed Radiance is not from 2020/9/3 or later.” And after I removing “radiance_check=True”, it can’t calculate. I record the screen below: [image] The Chinese words means: “This file is being used by a…

[Screenshot (217)] After removing the radiance_check condition ,it is working. Thanks for the update @chris
