Getting a type error converting array using PIL

Question

from PIL import Image
import numpy as np

pixels1 = Image.open('image.jpeg')

pixels = pixels1.load()

for i in range(pixels1.size[0]):
    for j in range(pixels1.size[1]):
        pixels[i,j] = (0, 0, 0)

pixels = np.asarray(pixels)
pixels = Image.fromarray(pixels)
pixels.show()

I get this error

TypeError: Cannot handle this data type: (1, 1), |O

Please share the entire error message. Also, why are you accessing the values individually like that? What are you trying to do? — AMC

The pixels variable is a PixelAccess object, used to access individual pixels. it is not the pixel data itself. if you want to see the modified image, use the pixels1 variable.

from PIL import Image
import numpy as np

pixels1 = Image.open('image.jpg')

pixels = pixels1.load()

for i in range(pixels1.size[0]):
    for j in range(pixels1.size[1]):
        pixels[i,j] = (0, 0, 0)

pixels = np.asarray(pixels1)
pixels = Image.fromarray(pixels)
pixels.show()

however I'm not sure why you convert the modified image to an array and then to image again, you can just do pixels1.show() after the loop.
