Hi, help me to rectify this error Traceback (most recent call last): File "main.py", line 73, in m = Model(input=[x, x_maps], output=sam_resnet([x, x_maps])) File "\sam-master\models.py", line 136, in sam_resnet nb_cols=3, nb_rows=3)(att_convlstm) File "\sam-master\keras\engine\base_layer.py", line 457, in call output = self.call(inputs, *kwargs) File "\sam-master\attentive_convlstm.py", line 154, in call input_length=input_shape[1]) File "\sam-master\keras\backend\theano_backend.py", line 1591, in rnn go_backwards=go_backwards) File "\Anaconda3\lib\site-packages\theano\scan_module\scan.py", line 773, in scan condition, outputs, updates = scan_utils.get_updates_and_outputs(fn(args)) File "\sam-master\keras\backend\theano_backend.py", line 1575, in _step outputs, new_states = step_function(inputs, states) File "\sam-master\attentive_convlstm.py", line 123, in step a = K.reshape(K.softmax(K.batch_flatten(e)), (x_shape[0], 1, x_shape[2], x_shape[3])) File "\sam-master\keras\backend\theano_backend.py", line 1101, in batch_flatten if None in x._keras_shape[1:]: TypeError: 'NoneType' object is not subscriptable thanks
