Essayer d'exécuter un modèle de keras formé avec le code python suivant:
from keras.preprocessing.image import img_to_array
from keras.models import load_model
from imutils.video import VideoStream
from threading import Thread
import numpy as np
import imutils
import time
import cv2
import os
MODEL_PATH = "/home/pi/Documents/converted_keras/keras_model.h5"
print("[info] loading model..")
model = load_model(MODEL_PATH)
print("[info] starting vid stream..")
vs = VideoStream(usePiCamera=True).start()
time.sleep(2.0)
while True:
frame = vs.Read()
frame = imutils.resize(frame, width=400)
image = cv2.resize(frame, (28, 28))
image = image.astype("float") / 255.0
image = img_to_array(image)
image = np.expand_dims(image, axis=0)
(fuel, redBall, whiteBall, none) = model.predict(image)[0]
label = "none"
proba = none
if fuel > none and fuel > redBall and fuel > whiteBall:
label = "Fuel"
proba = fuel
elif redBall > none and redBall > fuel and redBall > whiteBall:
label = "Red Ball"
proba = redBall
elif whiteBall > none and whiteBall > redBall and whiteBall > fuel:
label = "white ball"
proba = whiteBall
else:
label = "none"
proba = none
label = "{}:{:.2f%}".format(label, proba * 100)
frame = cv2.putText(frame, label, (10, 25),
cv2.FONT_HERSHEY_SIMPLEX, 0.7, (0, 255, 0), 2)
cv2.imshow("Frame", frame)
key = cv2.waitKey(1) & 0xFF
if key == ord("q"):
break
print("[info] cleaning up..")
cv2.destroyAllWindows()
vs.stop()
Lorsque je l'exécute avec python3, j'obtiens l'erreur suivante:
TypeError: __init__() got an unexpected keyword argument 'ragged'
Quelle est la cause de l'erreur et comment puis-je la contourner?
Versions: Keras v2.3.1 tensorflow v1.13.1
