AttributeError: 'RasterWindow' object has no attribute 'SetClientSizeWH'

[afk-moneymaker]

Hello, I have been trying to familiarize myself with the library. However, I encountered a problem. The spectral library calls SetClientSizeWH. If the call is changed to SetClientSize, the error does not occur anymore, but others are raised. I therefore assume that the library versions I am using are incompatible with each other. But which combination works?

Code

import os

from spectral import *
import spectral.io.envi as envi

if __name__ == "__main__":
    path = os.path.dirname(__file__) + "/../../data/raw/"
    header = path + "ENVIDATA.hdr"
    data = path + "ENVIDATA.dat"
    img = envi.open(header, data)

    view_indexed(img)

Hello,

view_indexed is now deprecated (I should add a warning for that). Please use the display functions here. So in your case, you would want to do something like

import spectral as spy
gt = img.read_band(0)
spy.imshow(classes=gt, interpolation='nearest')

Note that the classes keyword is primarily intended for displaying ground truth or classification masks (not actual image data).
