保存的每一张图片里面都显示好多张图片的内容，是代码哪块的问题啊各位

Question

import cv2
import multiprocessing
import os
import matplotlib.pyplot as plt
from PIL import Image
import numpy as np
def get_img(input_dir):
img_paths = []
for (path,dirname,filenames) in os.walk(input_dir):
for filename in filenames:
img_paths.append(path+'/'+filename)
print("img_paths:",img_paths)
return img_paths

def tran(img_paths,output_dir):
imread_failed = []

try:
    #img = cv2.imread(img_paths)
    img = Image.open(img_paths)
    pic = img.convert('RGBA') # 转为RGBA模式
    #print("哈哈哈哈哈哈")
    width,height = pic.size
    #print("哈哈哈哈哈哈")
    array = pic.load() # 获取图片像素操作入口
    for i in range(width):
        for j in range(height):
            pos = array[i,j] # 获得某个像素点，格式为(R,G,B,A)元组
            # 如果R G B三者都大于240(很接近白色了，数值可调整)
            isEdit = (sum([1 for x in pos[0:3] if x <= 0]) == 3)
            if isEdit:
                # 更改为透明
                array[i,j] = (255,255,255,0)


    #cv2.imwrite(output_dir + '/' + img_paths.split('/')[-1], pic)
    plt.imshow(pic, cmap=plt.cm.gray)
    # plt.axis('off')
    plt.savefig(output_dir + '/' + img_paths.split('/')[-1] + ".tiff")
    # pic.save("output_dir + '/' + img_paths.split('/')[-1].tiff")
    # cv2.waitKey(0)
    # cv2.destroyAllWindows()
except:
    imread_failed.append(img_paths)
return imread_failed

def main(input_dir,output_dir):
img_paths = get_img(input_dir)
scale = len(img_paths)

results = []
pool = multiprocessing.Pool(processes = 4)
for i,img_path in enumerate(img_paths):
    a = "#"* int(i/10)
    b = "."*(int(scale/10)-int(i/10))
    c = (i/scale)*100
    results.append(pool.apply_async(tran, (img_path,output_dir )))
    print('{:^3.3f}%[{}>>{}]'.format(c, a, b)) # 进度条（可用tqdm）
pool.close()                        # 调用join之前，先调用close函数，否则会出错。
pool.join()                         # join函数等待所有子进程结束
for result in results:
    print('image read failed!:', result.get())
print ("All done.")

if name == "main":
input_dir = "G:/aml/new/finalfile/train/LYA/" # 读取图片目录表
output_dir = "G:/aml/new/tran_bg/train/LYA/" # 保存图像目录
main(input_dir, output_dir)

我想要的是一张图片只有一个细胞，但生成了n个细胞一张图，不知道是代码哪里出问题了哎

你用的
plt.savefig(output_dir + '/' + img_paths.split('/')[-1] + ".tiff")
这个把你的图一起保存了,这一块放到for循环去
