Keras: model.add has invalid syntax

[Gagazet]

Good day! Trying to jump into keras, but have a pretty strange problem. Here is part of my code from ipython:

`from keras import backend as K
from keras.utils import np_utils
from keras.models import Sequential
from keras.layers import Dense, Dropout, Activation, Flatten
from keras.layers.convolutional import Convolution2D, MaxPooling2D
from keras.optimizers import SGD, RMSprop, adam
K.set_image_dim_ordering('tf')

input_shape = img_data_scaled[0].shape

model = Sequential()
model.add(Convolution2D(32, (3 ,3), padding='same', input_shape=input_shape))
model.add(Activation('relu'))
model.add(Convolution2D(32, (3, 3)))
model.add(Activation('relu'))
model.add(MaxPooling2D(pool_size=(2, 2)))
model.add(Dropout(0.5))
model.add(Flatten())
model.add(Dense(64))
model.add(Activation('relu'))
model.add(Dropout(0.5))
model.add(Dense(num_classes))
model.add(Activation('softmax'))

model.compile(loss='categorical_crossentropy', optimizer='rmsprop',metrics=["accuracy"])

hist = model.fit(X_train, y_train, batch_size = 32, nb_epoch = 20, verbose = 1, validation_data = (X_test, y_test))`

And, i have this problem:

File "<ipython-input-40-e57f946b3418>", line 16 model.add(Activation('relu')) ^ SyntaxError: invalid syntax

Really have no idea what it can be! Using python 2.7, last version of keras and ubuntu 14.
Can anyone quess, what is it?
Thank you~

You forget one parenthesis on the line above.

Oh god, you right. Tried to figure it out for 1h.
Thank you very much!
