We then convert this image object to a NumPy array using the numpy.array() method. We use the Image.fromarray() function to convert the array back to the PIL image object and finally display the image object using the show() method. import numpy as np from PIL import Image array = np...
TypeError: int() argument must be a string, a bytes-like object or a number, not 'Image' 解决办法如下: lst = list() for file_name in os.listdir(dir_image): image = PIL.Image.open(file_name) lst.append(np.array(image)) arr = numpy.array(lst) 即,在list中的元素都已转化为numpy....
