老师我这是怎么回事呢

老师，如果有的正例在topN里面没有被检测出来呢，精度该怎么算？

老师这是什么问题呢、

老师这个皮肤癌的代码例子里面在哪里加载了Y呢？网络怎么知道图片是正常的还是恶性的

老师，这里梯度应该是一个向量吧，如何理解这个平方项呢？

讲解机器学习例子的时候，可能有点讲错了。

老师，这个上采样是不是可以对图片进行无损放大哟？

老师我的虚拟环境和miniconda3不在一个地方

老师创立的新项目说缺解释器，但是我有pyth3.9，这是为啥呢

老师每次打开都是这样

老师我这个如何创立新文件呢

老师你看这个影响不

Person:
    amount = (, name, age):
        .name = name
        .age = age
        Person.amount += ():
        Person.amount -= ()

    ():
        .name.age

p = Person(, )

为什么运行这段的运行结果是"Object is being deleted"并没用使用del p呀？
