通过函数save()参数来决定是否在数据库中创建一条记录或者更新现存的记录。 构造一个新类,类有’Model’的行为,但我们只有检查一些条件后才会保存这个类的对象。这个新类继承’Model’,重写’Model’的’save()’ class ChildModel(Model): ... def save(self,args, **kwargs): ... if self.name=='abcd'...

super(ChildModel, self).save(*args, **kwargs) else: return None 实际上对应的保存动作发生在’Model’的save方法中。所以我们调用子类的的save()方法而非’Model’的方法.子类ChildModel的save()接收任何父类save()需要的参数,并传给父类方法。因此,子类save()方法参数列表中有*args和**kwargs,它们可以接...
问*args，**kwargs在此save方法中的作用EN我的观察是，没有任何数量的参数，无论是非关键字或关键字...

从文件中使用正确的args加载pytorch模型我能够完成这一点，只需将模型路径提供给from_pretrained（）函数。
