Tutorial 1: Fixed-Tilt Yearly Results Issue

[Funerus]

Hello,

As you can imagine, I've recently started working with bifacial_radiance and Python.

I've been following the same procedure uploaded for Tutorial 1; however, when I generate the sky (cumulative) I get an error message: "gencumulativesky is not recognized as an internal or external command".

I've copied the gencumulativesky.exe and falsecolor.exe files as well as the gencumsky folder from bifacial_radiance main to Radiance/bin.

Any idea on what could be going wrong?

I attempted setting fullYear to False, to use gendaylit instead. Although the sky seems to be generated fine in this case, I get an error in the octree creation demo.makeOct(demo.getfilelist()).

FileNotFoundError: [WinError 2] The system cannot find the file specified

I would really appreciate any sort of help!

If you need further details please let me know, Regards, Alex

Hi Alex,

Both errors seem related to perhaps the environment variable not knowing the right path to Radiance/bin. Can you please check they are in your system path?

Also, which version of radiance did you install? You can find this by typing into the terminal/python

    import bifacial_radiance
    bifacial_radiance.__version__  

(that is two underscores after and before version)

Hey Silvana,

Thank you so much for getting back to me! I really appreciate it.

First of all, regarding the version of Radiance. I believe it is Radiance 5.4a (2023-03-12). However, the code outputs '0+unknown'. I should note, that I am trying to run bifacial_radiance through the JupyterLab desktop version. It seems that I might have messed up somewhere in the installation process.

I also checked the system path (Environment variables --> System variables --> Path) C:\Program Files\Radiance\bin C:\Program Files\JupyterLab;C:Users\odyal\Projects

Note that bifacial_radiance is installed in: C:\Users\odyal\bifacial_radiance-main

I am not sure how the actual location of each software package is related to the Path thing. I will probably uninstall and re-install everything without the use of JupyterLab desktop.

I am at your mercy!

Cheers, Alex

Hi Alex,

would it help to jump into a quick call? What timezone are you in?

Hey Silvana,

That would be lovely! I live in the Netherlands and it is 16:45 right now.

I'm going through the installation one more time without diverging from the installation instructions. Could you give me some time to see whether I can make it work?

I will update you soon, Kind regards, Alex
