为什么我会收到“str”objet is not callable 错误？

Question

my code:

import cv2 import tensorflow as tf

CATEGORIES=['Dog','Cat']

def prepare(filepath):
    IMG_SIZE=50
    img_array = cv2.imread(filepath,cv2.IMGREAD_GRAYSCALE)
    new_array = cv2.resize(img_array,(IMG_SIZE,IMG_SIZE))
    return new_array.reshape(-1, IMG_SIZE, IMG_SIZE, 1)

model = tf.keras.models.load_model("64x3-CNN.model")

prediction = model.predict([prepare('dog.jpg')]) print(prediction)

my error:

TypeError                                 Traceback (most recent call last)
<ipython-input-8-182101876678> in <module>
     10     return new_array.reshape(-1, IMG_SIZE, IMG_SIZE, 1)
     11 
---> 12 model = tf.keras.models.load_model("64x3-CNN.model")
     13 
     14 prediction = model.predict([prepare('dog.jpg')])

TypeError: 'str' object is not callable

Answer 1

I faced the same error while loading a saved pb model in TensorFlow. Turns out that I didn't save the model using Keras, so had to load the model using tf.saved_model.load('model_directory') instead of using Keras.

Answer 2

May be these are the factors to produce this error....

1. You saved the model different name.
2. You saved the model in different directory with correct name or incorrect name
3. your extension is wrong

In your case, Your extension of the model is wrong since there is no extenison like model" Check Your extension of the model. It may "h5" https://www.tensorflow.org/tutorials/keras/save_and_load#hdf5_format
