Win32Exception - Daylight with Radiance Error

Karim · April 7, 2022, 10:24am

Hey lbt Team,

Rhino: 7.16
PYTHON: 3.7.9
RADIANCE 5.4a 2021-03-28 LBNL (5.4.947ea88a29)
LB version: 1.4.0

Im getting a weird Win3dException Error. A little background, I was running an sDA script which was working fine yesterday and for some reason today when I opened it up it did not work and this error popped up. I tried using the sample tutorial files to see whether i messed anything up but I get the same problem. Here is the error message:

Runtime error (Win32Exception): WindowsError

Traceback:
  line 439, in __init__, "C:\Program Files\Rhino 7\Plug-ins\IronPython\Lib\subprocess.py"
  line 316, in run, "C:\Users\karimd\ladybug_tools\python\Lib\site-packages\lbt_recipes\recipe.py"
  line 127, in script

Seems like im not allowed to upload attachments, but it’s in the
ladybug-tools-1-4-0\samples\honeybee-radiance folder honeybee-radiance titled annual_daylight.

Let me know if you need more info. Thanks!

Hey @Karim ,

It looks like somehow you lost access to run commands from Rhino. The part that is failing is the line of code where we actually start running the simulation:

github.com

ladybug-tools/lbt-recipes/blob/master/lbt_recipes/recipe.py#L316

    
      
          
          
    # execute command
              shell = False if os.name == 'nt' and not silent else True
              if settings.report_out:
                  process = subprocess.Popen(
                      command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=shell)
                  result = process.communicate()
                  print(result[0])
                  print(result[1])
              else:
                  process = subprocess.Popen(command, shell=shell)
                  result = process.communicate()  # freeze the canvas while running
              return folder
          
          
def output_value_by_name(self, output_name, project_folder=None):
              """Set the value of an input given the input name.

                  output_name: Text for the name of the output to be obtained.

Is this running on a machine controlled by an IT department? If so, you might have more luck if you install Ladybug Tools by using the free Pollination Grasshopper single-click installer:

The latest Pollination single-click installer puts the installation in “Program Files” by default, which can get around some of these IT restrictions.
