python - IndexError：使用 OpenCV 和 FaceRecognition 在 Python 中列出超出范围的索引

Question

import cv2
import numpy as np
import face_recognition
import os

path = 'Images'
images = []
classNames = []
myList = os.listdir(path)
print(myList)
for cl in myList:
    curImg = cv2.imread(f'{path}/{cl}')
    images.append(curImg)
    classNames.append(os.path.splitext(cl)[0])
print(classNames)

def findEncodings(images):
    encodeList = []
    for img in images:
        img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
        encode = face_recognition.face_encodings(img)[0]
        encodeList.append(encode)
    return encodeList

encodeListKnown = findEncodings(images)
print(len(encodeListKnown))

我现在真的看不到我的错误...控制台打印我->

好的解决方案是，在使用 face_recognition 时不要使用没有人脸的测试照片......
