问题记录：恢复某些层参数，遇到NotFoundError: Key conv2d_168/bias not found in checkpoint

问题描述：对网络结构做了些修改，导入已训练的参数，出现NotFoundError

相关程序：

#State where your log file is at.
log_dir = './log2'

#State where your checkpoint file is 
checkpoint_file = './log/model.ckpt-300068'

#Define the scopes that you want to exclude for restoration
exclude = ['conv_0','conv_1','conv_2']
variables_to_restore = slim.get_variables_to_restore(exclude=exclude)

#Now we create a saver function that actually restores the variables from a checkpoint file in a sess
saver = tf.train.Saver(variables_to_restore)
def restore_fn(sess):
	return saver.restore(sess,checkpoint_file)
sv = tf.train.Supervisor(logdir = log_dir,summary_op = None, init_fn = restore_fn) 

报错：

问题原因：没有导入参数

问题语句：

exclude = ['conv_0','conv_1','conv_2']
variables_to_restore = slim.get_variables_to_restore(exclude=exclude
