This section is just for testing the camera can work properly with the picamera package.
from typing import Counter
from ImageClassification.Predict import Prediction
import picamera
import time
counter = 1
while counter <= 5:
# take pic
camera = picamera.PiCamera()
camera.capture('fit.jpg')
print('camera take the picture')
Prediction('fit.jpg')
counter += 1

Use ngrok to make the image captured by the camera visible on the outer web browser.
Next, we can map the directory to the HTTPS URL and the directory can be accessed from outside with a web browser.
Access the image on a web browser with the URL.
Don't forget to change the URL in the python file every time you restart the ngrok.
After changing the URL, you can execute the python file again.
We will use SocketXP to take the place of ngrok and get the webhook URL. Remember that we assign the port number to be 80 in the python file, so we should connect to port 80 with SocketXP.
Next, we get the public URL that SocketXP issues for us.
Fill the Webhook URL section with the URL we gained from SocketXP. Don't forget to add /callback.

If you finish the above steps successfully, then you can interact with the Line Bot happily.
If there is any problem you want to ask, you can issue me here.
Have fun and stay cool~
