I get this error AttributeError: 'NoneType' object has no attribute 'array_interface' on colorization

Hello, thank you for this amazing project!

I'm able to launch test.py and the Gradio interface loads properly.
However, when I try to run the colorization process by uploading an image and pressing the button, I get this error:

File "/mnt/c/Control-Color/test.py", line 395, in is_gray_scale
img = Image.fromarray(img)
AttributeError: 'NoneType' object has no attribute 'array_interface'

Thanks a lot!

When you are testing in the browser, click the 'Upload Input Image' button.
