2. 当前目录运行

pip install -r requirements.txt

程序：

import os
import paddlehub as hub
import matplotlib
import matplotlib.pyplot as plt
import matplotlib.image as mpimg
import matplotlib.figure as figure
import numpy as np
matplotlib.use('TkAgg') 

base_dir = os.path.abspath('.')
input_img_path = base_dir+"/source/"
output_img_path = base_dir+"/target/"


humanseg = hub.Module(name="deeplabv3p_xception65_humanseg")

input_imgs_dirs = [input_img_path+p for p in os.listdir(input_img_path)]
output_img_dirs = [output_img_path+p.split(".")[0]+".png" for p in os.listdir(input_img_path)]
print(input_imgs_dirs)
print(output_img_dirs)

all =len(input_imgs_dirs)
i=0
for input in input_imgs_dirs:
    print("%d%%"%(i/all*100))
    results = humanseg.segmentation(data={"image":[input]})
    data = results[0]['data']
    plt.figure(figsize=[10,10])
    plt.imsave(output_img_dirs[i],data)
    # plt.imshow(data)
    # plt.axis("off")
    # plt.show()
    i+=1

NOTE：

1. MAC 和 Linux 上可以正常运行，windows 上需要安装docker 后运行
