I'm developing a deep learning model with tensor flow and python:
- First, using CNN layers, get features.
- Second, reshaping the feature map, I want to use LSTM layer.
However, a error with not-matching dimension...
ConcatOp : Dimensions of inputs should match: shape[0] = [71,48]
vs. shape[1] = [1200,24]
W_conv1 = weight_variable([1,conv_size,1,12])
b_conv1 = bias_variable([12])
h_conv1 = tf.nn.relu(conv2d(x_image, W_conv1)+ b_conv1)
h_pool1 = max_pool_1xn(h_conv1)
W_conv2 = weight_variable([1,conv_size,12,24])
b_conv2 = bias_variable([24])
h_conv2 = tf.nn.relu(conv2d(h_pool1, W_conv2) + b_conv2)
h_pool2 = max_pool_1xn(h_conv2)
W_conv3 = weight_variable([1,conv_size,24,48])
b_conv3 = bias_variable([48])
h_conv3 = tf.nn.relu(conv2d(h_pool2, W_conv3) + b_conv3)
h_pool3 = max_pool_1xn(h_conv3)
print(h_pool3.get_shape())
h3_rnn_input = tf.reshape(h_pool3, [-1,x_size/8,48])
num_layers = 1
lstm_size = 24
num_steps = 4
lstm_cell = tf.nn.rnn_cell.LSTMCell(lstm_size, initializer = tf.contrib.layers.xavier_initializer(uniform = False))
cell = tf.nn.rnn_cell.MultiRNNCell([lstm_cell]*num_layers)
init_state = cell.zero_state(batch_size,tf.float32)
cell_outputs = []
state = init_state
with tf.variable_scope("RNN") as scope:
for time_step in range(num_steps):
if time_step > 0: scope.reuse_variables()
cell_output, state = cell(h3_rnn_input[:,time_step,:],state) ***** Error In here...
