As mentioned in this question that we need sequential model to use .predict_classes
I am using this model but still getting
AttributeError: 'function' object has no attribute 'predict_classes'
error. I am using following code
def Build_Model_RNN_Text(word_index, embeddings_index, nclasses, MAX_SEQUENCE_LENGTH=500, EMBEDDING_DIM=50, dropout=0.5):
model = Sequential()
hidden_layer = 3
gru_node = 32
embedding_matrix = np.random.random((len(word_index) + 1, EMBEDDING_DIM))
for word, i in word_index.items():
embedding_vector = embeddings_index.get(word)
if embedding_vector is not None:
# words not found in embedding index will be all-zeros.
if len(embedding_matrix[i]) != len(embedding_vector):
print("could not broadcast input array from shape", str(len(embedding_matrix[i])),
"into shape", str(len(embedding_vector)), " Please make sure your"
" EMBEDDING_DIM is equal to embedding_vector file ,GloVe,")
exit(1)
embedding_matrix[i] = embedding_vector
model.add(Embedding(len(word_index) + 1,
EMBEDDING_DIM,
weights=[embedding_matrix],
input_length=MAX_SEQUENCE_LENGTH,
trainable=True))
print(gru_node)
for i in range(0,hidden_layer):
model.add(GRU(gru_node,return_sequences=True, recurrent_dropout=0.2))
model.add(Dropout(dropout))
model.add(GRU(gru_node, recurrent_dropout=0.2))
model.add(Dropout(dropout))
model.add(Dense(256, activation='relu'))
model.add(Dense(nclasses, activation='softmax'))
model.compile(loss='sparse_categorical_crossentropy',
optimizer='adam',
metrics=['accuracy'])
return model
Even when using .predict
, instead of .predict_classes
get I am getting same error
EDIT: I am using following code to call method
predicted = Build_Model_RNN_Text.predict_classes(X_test_Glove)
The error is caused by the fact that you were not calling your function in order to get its output. Simply do
predicted = Build_Model_RNN_Text(<<args>>).predict_classes(X_test_Glove)
Where you need to replace <<args>>
with the required arguments for your function. It seems like maybe you had intended for Build_Model_RNN_Text
to be a class
instead?
Either way, how exactly were you expecting this to work, as you were not providing the required arguments word_index
, embeddings_index
, and nclasses
