对数据进行完预处理之后运行train.py，到了写入保存点这一步会报错显示无法创建保存点 其中checkpoint_path被设定为./chkpnt

if iter_id % CHECKPOINT_PERIOD == 0 and args.checkpoint_path is not None: #写保存点
    dir_name = args.checkpoint_path + "/" + str(iter_id)
    fluid.io.save_persistables(exe, dirname=dir_name)
    print("Saved checkpoint: %s" % (dir_name))

终端显示

请问为什么会出现这种现象呢？
