我正在使用 tensorflow 和python开发深度学习模型:
但是,尺寸不匹配的错误...
ConcatOp:输入的尺寸应匹配:
shape[0] = [71,48]
与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...
最佳答案
当您输入到rnn单元格时,输入张量和状态张量的批处理大小应相同。
在错误消息中,它说h3_rnn_input[:,time_step,:]
具有[71,48]
的形状,而state
具有[1200,24]
的形状
您需要做的是使第一个尺寸(batch_size)相同。
如果不需要数字71,请检查卷积部分。步幅/填充可能很重要。
