not enough values to unpack

While running the "Testing image reading and panel detection" code from https://micasense.github.io/imageprocessing/MicaSense%20Image%20Processing%20Setup.html

from micasense.image import Image
# imagePath = os.path.join('.','data','0000SET','000')
# imageName = glob.glob(os.path.join(imagePath,'IMG_0000_1.tif'))[0]

img = Image('IMG_0000_1.tif')
img.plot_raw(figsize=(8.73,8.73));

from micasense.panel import Panel
panel = Panel(img)
if not panel.panel_detected():
    raise IOError("Panel Not Detected! Check your installation of pyzbar")
else:
    panel.plot(figsize=(8,8));

print('Success! Now you are ready for Part 1 of the tutorial.')

I am getting the following error,

ValueError: not enough values to unpack (expected 2, got 0)

I have installed all of the prerequisites libraries and I'm not sure what the issue is with the vignette function. The image used is from Altum-PT
