ValueError: Attempt to convert a value (<PIL.PngImagePlugin.PngImageFile image mode=RGB size=519x600 at 0x7F95AD916518>) with an unsupported type

问题

while i was opening and decoding an image from python with tensorflow i got an error

%tensorflow_version 2.x
import tensorflow as tf
from PIL import Image
import requests
from io import BytesIO
response = requests.get(r'https://upload.wikimedia.org/wikipedia/commons/e/e9/Felis_silvestris_silvestris_small_gradual_decrease_of_quality.png')
img = Image.open(BytesIO(response.content))

tf_image = tf.io.read_file(img)

error is hapenning when i used tf.io.read_file(img) Throws error of
