Как корректно написать код на питоне(у меня много ошибок)

count = 0
videoFile = "C:\Users\Admin\Downloads\myvideo" # тут папка с моим набором видеофайлов формат mp4
cap = cv2.VideoCapture(videoFile)   # capturing the video from the given path
frameRate = cap.get(5) #frame rate
x=1
while(cap.isOpened()):
    frameId = cap.get(1) #current frame number
    ret, frame = cap.read()
    if (ret != True):
        break
    if (frameId % math.floor(frameRate) == 0):
        filename ="frame%d.jpg" % count;count+=1
        cv2.imwrite(filename, frame)
cap.release()
print ("Done!")

>>> img = plt.imread('frame0.jpg')   # reading image using its name

#second working with labels
data = pd.read_csv('C:\Users\Admin\Downloads\mapping.csv')     # reading the csv file
