ValueError: output array is read-only

[yuxijin]

Hi, guys. I was attempting to run the decompose.py file by command 'python decompose.py test.jpg', while I got an error like the following:
Traceback (most recent call last): File "decompose.py", line 125, in <module> r, s, decomposition = solver.solve() File "/home/jinyuxi/Documents/intrinsic/bell2014/solver.py", line 38, in solve self.initialize_intensities() File "/home/jinyuxi/Documents/intrinsic/bell2014/solver.py", line 105, in initialize_intensities samples[:, 0] *= self.params.kmeans_intensity_scale ValueError: output array is read-only
I don't know why and how to fix this issue. Is there anybody can tell me what should I do?

Not sure why it isn't letting you modify -- looks like the array is not writeable. You could try changing the code to add this line before the error:
samples = np.copy(samples)

If that works, then a more general solution might be this code instead:

if not samples.flags['WRITEABLE']):
    samples = np.copy(samples)

Thank for your suggestion, I'll try it later.
