'numpy.ndarray' object has no attribute 'mode'

I got an error with this code:

import PIL.ImageOps
inverted_image = PIL.ImageOps.invert(image)

The traceback is

Traceback (most recent call last):
  File "filter.py", line 32, in <module>
    inverted_image = PIL.ImageOps.invert(denoise)
  File "/usr/lib/python3/dist-packages/PIL/ImageOps.py", line 367, in invert
    return _lut(image, lut)
  File "/usr/lib/python3/dist-packages/PIL/ImageOps.py", line 48, in _lut
    if image.mode == "P":
AttributeError: 'numpy.ndarray' object has no attribute 'mode'

How can I fix it?
