Ladybug Installation problems

1. You downloaded Ladybug, Installed it but as soon as you drag a component into the canvas you see something similar to this:

You probably don't have GHPython installed on your system. Download GHPython and install it and it should work fine.

2. You still see the image above in case 1 however you have GHPython already installed. What about that?

In this case probably the GHA component is blocked. Find GHPython.GHA on your system (usually at: C:\Users\%username%\AppData\Roaming\Grasshopper\Libraries) . Right click, go to properties and select unblock.

To make sure that GHPython is working fine on your system open the attachment file (testGHPython.gh). You should see something similar to the image below on your screen when you open the file:

If you see the something similar you should be fine to go! Try to open one of the example files.

3. You have Ladybug running but in some of the case the output is missing. You see something similar to this:

or this

This one is because you are using old version of GHPython. Close the file without saving. Download the new version and install it and re-open the file. It should work fine now.

Hope it helps,

Mostapha

Mostapha, most of my students were able to install Ladybug successfully but one student gets an error message from the Ladybug component. 1.Solution exception: Object reference not set to an instance of an object. Aa with the person above, Rhino GH crashed repeatedly on trying to get the program to work. It has not been possible for us to open the component for editing. Any ideas would be greatly appreciated.

Hi Nancy, This is an issue with GHPython component. Can s/he open and edit a GHPython component? What is the version of GHPython, Grasshopper and Rhino? Are they updated?

Hi Nina -- please don't use old versions of GhPython today. For your own sake: the code they save might not be forward and backward compatible and they are no longer supported. The only supported one is GhPython 0.6.0.3, along Rhino 5 SR12 or SR13.
