layout.show() error #48

Closed prabudhya closed 7 years ago

prabudhya commented 7 years ago

Hello,

I am trying to run the first script on the documentation page:

The Code: `from gdsCAD import *

cell=core.Cell('TOP')

for l in (3,6,10): box=shapes.Box((-l,-l), (l,l), width=0.2, layer=2) cell.add(box)

layout = core.Layout('LIBRARY') layout.add(cell)

layout.save('output.gds') layout.show() `

I am getting the following error: Writing the following cells TOP: Cell ("TOP", 3 elements, 0 references) Traceback (most recent call last): File "p1.py", line 18, in layout.show() File "/Users/Prabudhya/anaconda2/lib/python2.7/site-packages/gdsCAD-0.4.5-py2.7.egg/gdsCAD/core.py", line 82, in _show artists=self.artist() File "/Users/Prabudhya/anaconda2/lib/python2.7/site-packages/gdsCAD-0.4.5-py2.7.egg/gdsCAD/core.py", line 1132, in artist artists += c.artist() File "/Users/Prabudhya/anaconda2/lib/python2.7/site-packages/gdsCAD-0.4.5-py2.7.egg/gdsCAD/core.py", line 1389, in artist art+=e.artist() File "/Users/Prabudhya/anaconda2/lib/python2.7/site-packages/gdsCAD-0.4.5-py2.7.egg/gdsCAD/core.py", line 477, in artist return [descartes.PolygonPatch(poly, lw=0, **self._layer_properties(self.layer))] File "/Users/Prabudhya/anaconda2/lib/python2.7/site-packages/gdsCAD-0.4.5-py2.7.egg/gdsCAD/core.py", line 105, in _layer_properties colors += matplotlib.cm.gist_ncar(np.linspace(0.98, 0, 15)) TypeError: ufunc 'add' did not contain a loop with signature matching types dtype('S32') dtype('S32') dtype('S32')

I am not sure how to solve this problem. Thanks for you help.

solution seems to be the same as that of #36 in the thread change line 105 in core.py to : colors += list(matplotlib.cm.gist_ncar(np.linspace(0.98, 0,15)))
