I run "ConvGRU2D/examples/bidirectional_conv_gru.py" (copied to "/home/xxx/Desktop/ConvGRUtestNivNayman/test.py") I got:

Traceback (most recent call last): File "/home/xxx/Desktop/ConvGRUtestNivNayman/test.py", line 19, in input_shape=(None, 40, 40, 1), merge_mode='sum')) File "/home/xxx/tensorflow/lib/python3.5/site-packages/keras/models.py", line 497, in add layer(x) File "/home/xxx/tensorflow/lib/python3.5/site-packages/keras/layers/wrappers.py", line 325, in call return super(Bidirectional, self).call(inputs, kwargs) File "/home/xxx/tensorflow/lib/python3.5/site-packages/keras/engine/topology.py", line 619, in call output = self.call(inputs, kwargs) File "/home/xxx/tensorflow/lib/python3.5/site-packages/keras/layers/wrappers.py", line 403, in call y = self.forward_layer.call(inputs, **kwargs) File "/home/xxx/tensorflow/lib/python3.5/site-packages/keras/layers/convolutional_recurrent.py", line 1513, in call initial_state=initial_state) File "/home/xxx/tensorflow/lib/python3.5/site-packages/keras/layers/convolutional_recurrent.py", line 376, in call input_length=timesteps) File "/home/xxx/tensorflow/lib/python3.5/site-packages/keras/backend/tensorflow_backend.py", line 2771, in rnn swap_memory=True) File "/home/xxx/tensorflow/lib/python3.5/site-packages/tensorflow/python/ops/control_flow_ops.py", line 3096, in while_loop result = loop_context.BuildLoop(cond, body, loop_vars, shape_invariants) File "/home/xxx/tensorflow/lib/python3.5/site-packages/tensorflow/python/ops/control_flow_ops.py", line 2874, in BuildLoop pred, body, original_loop_vars, loop_vars, shape_invariants) File "/home/xxx/tensorflow/lib/python3.5/site-packages/tensorflow/python/ops/control_flow_ops.py", line 2836, in _BuildLoop nest.assert_same_structure(list(packed_vars_for_body), list(body_result)) File "/home/xxx/tensorflow/lib/python3.5/site-packages/tensorflow/python/util/nest.py", line 266, in assert_same_structure % (len_nest1, nest1, len_nest2, nest2)) ValueError: The two structures don't have the same number of elements.

First structure (4 elements): [<tf.Tensor 'bidirectional_1/while/Identity:0' shape=() dtype=int32>, <tensorflow.python.ops.tensor_array_ops.TensorArray object at 0x7f90e8c1c668>, <tf.Tensor 'bidirectional_1/while/Identity_2:0' shape=(?, 40, 40, 40) dtype=float32>, <tf.Tensor 'bidirectional_1/while/Identity_3:0' shape=(?, 40, 40, 40) dtype=float32>]

Second structure (3 elements): [<tf.Tensor 'bidirectional_1/while/add_6:0' shape=() dtype=int32>, <tensorflow.python.util.tf_should_use._add_should_use_warning..TFShouldUseWarningWrapper object at 0x7f90ae04e860>, <tf.Tensor 'bidirectional_1/while/add_5:0' shape=(?, 40, 40, 40) dtype=float32>]

I use Tensorflow-gpu 1.6.0 and python 3.5.2. I really need a Convolutional-GRU layer but I don't know what went wrong.

Facing the same issue. Has someone got a resolve?
