سلام خدمت دوستان گلم.
من از کد زیر استفاده کردم برای تولید onehot در sklearn و خطا میده:
batch_size = 30
num_classes = 36
epochs = 30
input_shape = (224, 224, 3)
from sklearn.preprocessing import LabelEncoder
le = LabelEncoder()
le.fit(train_labels)
# encode wine type labels
train_labels_enc = le.transform(train_labels)
validation_labels_enc = le.transform(validation_labels)
print(train_labels[0:5], train_labels_enc[0:5])
y contains previously unseen labels:
