下面代码只需32 * 32输入,我想输入128 * 128图像,如何去做。代码来自教程 - https://github.com/awjuliani/TF-Tutorials/blob/master/DCGAN.ipynb
def generator(z):
zP = slim.fully_connected(z,4*4*256,normalizer_fn=slim.batch_norm,\
activation_fn=tf.nn.relu,scope='g_project',weights_initializer=initializer)
zCon = tf.reshape(zP,[-1,4,4,256])
gen1 = slim.convolution2d_transpose(\
zCon,num_outputs=64,kernel_size=[5,5],stride=[2,2],\
padding="SAME",normalizer_fn=slim.batch_norm,\
activation_fn=tf.nn.relu,scope='g_conv1', weights_initializer=initializer)
gen2 = slim.convolution2d_transpose(\
gen1,num_outputs=32,kernel_size=[5,5],stride=[2,2],\
padding="SAME",normalizer_fn=slim.batch_norm,\
activation_fn=tf.nn.relu,scope='g_conv2', weights_initializer=initializer)
gen3 = slim.convolution2d_transpose(\
gen2,num_outputs=16,kernel_size=[5,5],stride=[2,2],\
padding="SAME",normalizer_fn=slim.batch_norm,\
activation_fn=tf.nn.relu,scope='g_conv3', weights_initializer=initializer)
g_out = slim.convolution2d_transpose(\
gen3,num_outputs=1,kernel_size=[32,32],padding="SAME",\
biases_initializer=None,activation_fn=tf.nn.tanh,\
scope='g_out', weights_initializer=initializer)
return g_out
def discriminator(bottom,reuse = False):
dis1 = slim.convolution2d(bottom,16,[4,4],stride=[2,2],padding="SAME",\
biases_initializer=None,activation_fn=lrelu,\
reuse=reuse,scope='d_conv1',weights_initializer=initializer)
dis2 = slim.convolution2d(dis1,32,[4,4],stride=[2,2],padding="SAME",\
normalizer_fn=slim.batch_norm,activation_fn=lrelu,\
reuse=reuse,scope='d_conv2', weights_initializer=initializer)
dis3 = slim.convolution2d(dis2,64,[4,4],stride=[2,2],padding="SAME",\
normalizer_fn=slim.batch_norm,activation_fn=lrelu,\
reuse=reuse,scope='d_conv3',weights_initializer=initializer)
d_out = slim.fully_connected(slim.flatten(dis3),1,activation_fn=tf.nn.sigmoid,\
reuse=reuse,scope='d_out', weights_initializer=initializer)
return d_out
以下是我输入128 * 128张图像时出现的错误。
Trying to share variable d_out/weights, but specified shape (1024, 1) and found shape (16384, 1).
答案 0 :(得分:0)
生成器生成32 * 32个图像,因此当我们在鉴别器中提供任何其他维度时,它会导致给定的错误。
解决方案是从发生器生成128 * 128个图像 1.添加更多没有。层(在这种情况下为2) 2.更改发生器的输入
zP = slim.fully_connected(z,16*16*256,normalizer_fn=slim.batch_norm,\
activation_fn=tf.nn.relu,scope='g_project',weights_initializer=initializer)
zCon = tf.reshape(zP,[-1,16,16,256])
