Run with Rhino64 to have all the components!

I had the same, Windows 7. I used the mixed installation of the previous version of the plug-in with the new.

I'm having the same issue as Madeline Spinski, Machine Learning tools are the only components appearing. Also on Windows 10.

I installed Lunchbox and the only tab that shows up in Machine Learning, all the other tools aren't there. I've tried uninstalling it and reinstalling but it doesn't change. Using windows 10

Having a problem with the excel read component. 

I get this error message...

System.NullReferenceException: Object reference not set to an instance of an object.
at Grasshopper.Kernel.GH_Component.GH_StructureIterator.SetDataTree(Int32 index, IGH_DataTree tree) in C:\dev\grasshopper\1.0\root\src\GH_StructureIterator.vb:line 1296
at LunchBox.WF_ExcelReadNew.SolveInstance(IGH_DataAccess DA)

why and how to fix...

Has anyone used the new machine learning components? I don't really know where to start with them, but I want to learn.

I am trying to write a script that tesseltes regular hexagons across a surface using the hexagon cells panel. So that no matter the input surface/rectangles dimensions- those hexagons are as close to regular as possible. I know that the width-to-height ratio of a hexagon resting on a side is 2*sqrt(3)/3 (to calculate number of U to v tiling) but I fail to understand the t-parameter and I'm unable to attain the regular hexagons. Can you help?

Dear all,

Thanks for all of the continued interest. To be honest, I haven't been keeping tabs on this group as much as I would like since I've started my new business.

I have released a new version of LunchBox over at Food4Rhino that you might be interested in checking out.  The new version is provided as a ClickOnce installer as well as a ZIP file containing the latest plugin files. Hopefully by providing both it is easier for everyone to get up and running.

when using the excel read (legacy), i get this error:

0. System.Runtime.InteropServices.COMException (0x800401E3): Vorgang nicht verfügbar. (Ausnahme von HRESULT: 0x800401E3 (MK_E_UNAVAILABLE))
   bei System.Runtime.InteropServices.Marshal.GetActiveObject(Guid& rclsid, IntPtr reserved, Object& ppunk)
   bei System.Runtime.InteropServices.Marshal.GetActiveObject(String progID)
   bei LunchBox.WF_ExcelRead.SolveInstance(IGH_DataAccess DA)

any ideas?

thank you!
