install tensorflow

sudo pip3 install  tensorflow

install other Dependent tools :numpy，tensorboard，markdown .....
in my case is tensorflow 1.9 so numpy version is 1.13.0,if numpy 1.16 or higher is not work

see https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/installation.md

if use raspberrt pi camera: Because my video is reddish, so i change the white balance

from picamera import PiCamera
camera = PiCamera()
camera.awb_mode='off'
#change white balance 
camera.awb_gains=(1.0,1.2)
camera.resolution =(640 ,480)

if use usb camera:

import cv2
video = cv2.VideoCapture(0)

cap = cv2.VideoCapture("your video name")
