My Jupyter Notebook has the following code to upload an image to Colab:
from google.colab import files
uploaded = files.upload()
I get prompted
from deepface import DeepFace
import cv2
import matplotlib.pyplot as plt
from google.colab import files
from io import BytesIO
from PIL import Image
uploaded = files.upload()
next line
# im = Image.open(BytesIO(uploaded['img.PNG']))
img = cv2.imread("theCorona.PNG")
plt.imshow(img[:,:, ::-1])
plt.show()
