NotFoundError: Unsuccessful TensorSliceReader constructor: Failed to find any matching files for xxx

之前在Ubuntu中做训练没问题，后来在win7中训练出现了以下问题。
环境：TensorFlow 1.5

NotFoundError: Unsuccessful TensorSliceReader constructor: Failed to find any matching files for C://spyderwork//catanddog//logs//train//model.ckpt-14999

[[Node: save/RestoreV2 = RestoreV2[dtypes=[DT_FLOAT], _device=”/job:localhost/replica:0/task:0/device:CPU:0”](_arg_save/Const_0_0, save/RestoreV2/tensor_names, save/RestoreV2/shape_and_slices)]]

出现上述问题的位置：

 ckpt=tf.train.get_checkpoint_state(logs_train_dir)if ckpt and ckpt.model_checkpoint_path:global_step=ckpt.model_checkpoint_path.split('/')[-1].split('-')[-1]saver.restore(sess,ckpt.model_checkpoint_path)#出错在该地

restore()的API如下
”

  def restore(self, sess, save_path):"""Restores previously saved variables.This method runs the ops added by the constructor for restoring variables.It requires a session in which the graph was launched.  The variables torestore do not have to have been initialized, as restoring is itself a wayto initialize variables.The `save_path` argument is typically a value previously returned from a`save()` call, or a call to `latest_checkpoint()`.Args:sess: A `Session` to use to restore the parameters. None in eager mode.save_path: Path where parameters were previously saved.Raises:ValueError: If save_path is None."""if self._is_empty:returnif save_path is None:raise ValueError("Can't load save_path when it is None.")logging.info("Restoring parameters from %s", save_path)if context.in_graph_mode():sess.run(self.saver_def.restore_op_name,{self.saver_def.filename_tensor_name: save_path})else:self._build_eager(save_path, build_save=False, build_restore=True)

restore的save_path参数为先前保存checkpoint的地址—“Path where parameters were previously saved。
之前保存checkpoint的代码为：

checkpoint_path = os.path.join(logs_train_dir, 'model.ckpt')
saver.save(sess, checkpoint_path, global_step=step)

checkpoint打印出来的地址为C:/spyderwork/catanddog/logs/train/model.ckpt-14999
而ckpt.model_checkpoint_path打印出来为C://spyderwork//catanddog//logs//train//model.ckpt-14999

这一块不知道是TensorFlow在windows中的bug还是其他原因，所以会出现这类错误。
修改方法1：
将以下代码

ckpt=tf.train.get_checkpoint_state(logs_train_dir)if ckpt and ckpt.model_checkpoint_path:global_step=ckpt.model_checkpoint_path.split('/')[-1].split('-')[-1]saver.restore(sess,ckpt.model_checkpoint_path)#出错在该地

换成

ckpt=tf.train.get_checkpoint_state(logs_train_dir)if ckpt and ckpt.model_checkpoint_path:global_step=ckpt.model_checkpoint_path.split('/')[-1].split('-')[-1]checkpoint_path = os.path.join(logs_train_dir, 'model.ckpt')saver.restore(sess,checkpoint_path)

修改方法2：

ckpt=tf.train.get_checkpoint_state(logs_train_dir)if ckpt and ckpt.model_checkpoint_path:global_step=ckpt.model_checkpoint_path.split('/')[-1].split('-')[-1]saver.restore(sess,'C:/spyderwork/catanddog/logs/train/model.ckpt-14999')或者ckpt=tf.train.get_checkpoint_state(logs_train_dir)if ckpt and ckpt.model_checkpoint_path:global_step=ckpt.model_checkpoint_path.split('/')[-1].split('-')[-1]saver.restore(sess,'./logs/train/model.ckpt-14999')

注：修改时请根据自己的路径进行修改
