Hello there,

When I try to import scipy.signal in 12.1.77 I get this;

Python 2.6.4 (r264:75706, Jul 4 2012, 11:56:27) on win32
Houdini 12.1.77 hou module imported.
Type “help”, “copyright”, “credits” or “license” for more information.
>>> import scipy.signal
Traceback (most recent call last):
File “<console>”, line 1, in <module>

from _cephes import *
ImportError: DLL load failed: The specified module could not be found.

which is a bit strange as it used to work fine in 12.0(543.9).

So, does anybody out there know why this happens and/or any workarounds? Currently I'm back on using 12.0 and don't really want to upgrade until I've figured this out…

btw, I use these 64 bit versions of numpy/scipy:

Any and all help, hints or anything else appreciated.

Both grid geometries are incoming through input and , respectively. Problem is, it seems only the first of them cooks.

Maybe I have to create two separate sops…

hello there…


If I have a grid sop connected to a python sop I can modify the incoming grid sop's geometry with setPointFloatAttribValues through hou.pwd().geometry().

However, I'd like to modify two grids.

I've tried,

hou.cd('/obj/geo1/grid2')
geo2 = hou.pwd().geometry()

or

thisnode = hou.pwd()
inputs = thisnode.inputs()
geo2 = inputs.geometry()

and some other methods, but all attempts to edit the second geometry yields ‘GeometryPermissonError: Geometry is read-only.’

How can I modify the second geometry…?
