在下面的代码中，我试图获取数组中每个图像的最高概率。它给了我以下错误
TypeError: Fetch argument None has invalid type <class 'NoneType'>
程序代码：
categories = #labels
test_img = []
probab=[]
classes=[]
true_labels = np.array(categories)
new_model = tf.keras.models.load_model("multi25.h5", custom_objects={'KerasLayer': hub.KerasLayer})
def load(filename):
np_image = Image.open(filename)
np_image = np.array(np_image).astype('float32')/255
np_image = transform.resize(np_image, (224, 224, 3))
np_image = np.expand_dims(np_image, axis=0)
return np_image
for i in os.listdir(data_root):
print(i)
loc= data_root+"//"+i
test_img.append(load(loc))
pred= new_model.predict(test_img)
classes.append(true_labels[np.argmax(pred, axis=-1)])
with tf.Session() as sess:
probab=tf.reduce_max(pred, axis=1).eval()
sess.run(print(probab))
print(test_img+" "+classes+" "+probab)
以下代码中出现错误，我在其中使用reduce_max函数获取最大概率。
probab=tf.reduce_max(pred, axis=1).eval()
sess.run(print(probab))
我已经尝试了其他解决方案，其中我将功能更改为reduce_indices，尝试了不运行会话等。Pred变量没有nonetype。我无法很好地理解错误
这是回溯
