这两句代码我应该怎么改啊，老提示错误，求指教

你需要把完整的可运行的代码，以及错误提示都贴上来

[Mo Meak]

@kidswong999 import sensor, time, image

SUB = "s2"
NUM_SUBJECTS = 5
NUM_SUBJECTS_IMGS = 10

img = image.Image("orl_faces/%s/wx.jpg"%(SUB)).mask_ellipse()
d0 = img.find_lbp((0, 0, img.width(), img.height()))
img = None

print("")
for s in range(1, NUM_SUBJECTS+1):
dist = 0
for i in range(2, NUM_SUBJECTS_IMGS+1):
img = image.Image("orl_faces/s%d/%d.pgm"%(s, i)).mask_ellipse()
d1 = img.find_lbp((0, 0, img.width(), img.height()))
dist += image.match_descriptor(d0, d1)
print("Average dist for subject %d: %d"%(s, dist/NUM_SUBJECTS_IMGS))
这是完整的代码

你需要把orl_faces文件夹放到SD卡里，参照教程。

@kidswong999 在 人脸识别，求指教 中说：

orl_faces

是这个文件夹吗 ？
