Honeybee Radiance analysis Runtime Error: Win32Exception

raasmar · August 31, 2023, 6:26am

Hello, I am new to Grasshopper and started using Honeybee yesterday. I was learning how to proceed with a Radiance analysis on honeybee legacy. At first I didn’t have the additional Radiance, Openstudio, Daysim… so I downloaded them. Then, I realized it was easier for me to work on Honeybee (not the legacy one) so I added the newest plugins and when running the radiance simulation, I am running into an error I don’t know how to solve. I’ve tried uninstalling and installing everything back again but can’t seem to find the problem and I don’t really have much knowledge in python so I came here for advice. I am getting the following:

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\raasmar\ladybug_tools\python\Lib\site-packages\lbt_recipes\recipe.py”
line 87, in script

Here is also a screenshot of it:

Hi @raasmar ,

Are you perchance on a machine that is governed by IT or some other antivirus software. Given the line of code that the component is failing on:

github.com

ladybug-tools/lbt-recipes/blob/d8ea4a46caf1be0d7fab78c8d0442c5c25350790/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.
          
              Args:
                  output_name: Text for the name of the output to be obtained.
                  project_folder: The full path to the project folder containing
                      completed recipe results. If None, the default_project_folder on

… I suspect that there may be something that is preventing the command from running the executable of the simulation.

Having your antivirus software greenlight everything in the ladybug_tools installation folder should get it to work.

Hi @chris ,
Yes in fact my PC is governed by an IT department. I wondered if that was the actual problem, so thanks for confirming that. I’ll ask them to give me permission to the whole ladybug_tools folder and try again.
Thanks again for the answer
