Olá pessoal tudo bem? Estou fazendo um projeto na faculdade com o teachable machine e estou tendo problemas para rodar ele no VS code, estou com o Python 3.10 e com as versões
- tensorflow==2.9.0
- keras==2.9.0
- opencv-python==4.8.1.78
- numpy==1.24.4
Código do Tensor Flow:
from keras.models import load_model
import cv2 # Install opencv-python
import numpy as np
# Disable scientific notation for clarity
np.set_printoptions(suppress=True)
# Load the model
model = load_model('/content/keras_model.h5')
# Load the labels
class_names = open("labels.txt", "r").readlines()
# CAMERA can be 0 or 1 based on default camera of your computer
camera = cv2.VideoCapture(0)
while True:
# Grab the webcamera's image.
ret, image = camera.read()
# Resize the raw image into (224-height,224-width) pixels
image = cv2.resize(image, (224, 224), interpolation=cv2.INTER_AREA)
# Show the image in a window
cv2.imshow("Webcam Image", image)
# Make the image a numpy array and reshape it to the models input shape.
image = np.asarray(image, dtype=np.float32).reshape(1, 224, 224, 3)
# Normalize the image array
image = (image / 127.5) - 1
# Predicts the model
prediction = model.predict(image)
index = np.argmax(prediction)
class_name = class_names[index]
confidence_score = prediction[0][index]
# Print prediction and confidence score
print("Class:", class_name[2:], end="")
print("Confidence Score:", str(np.round(confidence_score * 100))[:-2], "%")
# Listen to the keyboard for presses.
keyboard_input = cv2.waitKey(1)
# 27 is the ASCII for the esc key on your keyboard.
if keyboard_input == 27:
break
camera.release()
cv2.destroyAllWindows()
Também estou com os caminhos corretos para o Keras_models e Labels conforme mostra no código e por fim o erro que me mostra quando tento executar é esse aqui:
