在进行图像处理时，我得到了一个(ValueError:未能找到在模式‘i’中读取指定文件的格式)：

limit = 20
p1_image = [None]*limit
j = 0
for i in p1:
if(j < limit):
p1_image[j] = imread("C:/Users/IMA/Documents/ML/image/p1/"+i)

很可能您的目录中有非映像文件。
- 您可以将非映像文件移动到另一个目录，或者需要指定图像扩展名.
。
例如:使用glob获取所有png扩展名文件。
import matplotlib.pyplot as plt
from skimage.color import rgb2gray
from skimage.transform import resize
from skimage.io import imread, imshow
import pandas as pd
import numpy as np
import os
from glob import glob
import warnings
warnings.simplefilter('ignore')
path = "C:/Users/IMA/Documents/ML/image/p1/*.png"
p1 = glob(path)
p2 = os.listdir("C:/Users/IMA/Documents/ML/image/p2")
limit = 20
p1_image = [None]*limit
j = 0
for i in p1:
if j < limit:
p1_image[j] = imread(i)
j += 1
