这是由于 要恢复的变量设置 和 optimizer的摆放位置出错造成的。
解决办法：
更换 指定恢复变量 和 optimizer 的摆放位置：
opt = tf.train.AdamOptimizer(learning_rate=LEARNING_RATE)
variables_to_restore = slim.get_variables_to_restore()改为
variables_to_restore = slim.get_variables_to_restore()
opt = tf.train.AdamOptimizer(learning_rate=LEARNING_RATE)
