Every time I call draw() or show() I get the following error: TypeError: draw() got an unexpected keyword argument 'color'

File "C:\Users\<username>\Documents\test_simplecv.py", line 7, in <module> calib.show() File "c:\Python27\Lib\site-packages\SimpleCV-1.3-py2.7.egg\SimpleCV\Features\Features.py", line 120, in show self.draw(color, width, autocolor) File "c:\Python27\Lib\site-packages\SimpleCV-1.3-py2.7.egg\SimpleCV\Features\Features.py", line 93, in draw f.draw(color=color,width=width)

This was all that I was trying to do: import SimpleCV

testimg = SimpleCV.Image('calibration.jpg') calib = testimg.findChessboard((9,6)) calib.show()

Quick and dirty solution:

testimg = SimpleCV.Image('calibration.jpg') 
calib = testimg.findChessboard((9,6)) 
calib[0].show()

It is because in the calib FeatureSet there is only one Feature the Chessboard(Feature), and this overrides the draw method of its superclass (Feature) that no more accepts color as a parameter. Therefore you cannot call draw on the FeatureSet calib but only on its subelement calib[0].

I'd recommend you getting a good IDE that supports debugging and jumping to definitions, so you could quickly debug these problems yourself. Free IDEs will do it such as:
