Plot_loss_curve() takes 1 positional argument but 2 were given

This error message indicates that the function `Plot_loss_curve()` was called with too many arguments. The function expects only one positional argument, but it was passed two.

To fix this error, you can check the function definition and make sure that it only accepts one argument. You can also check where the function is called and make sure that only one argument is passed to it.

If you need to pass more than one argument to the function, you can modify the function definition to accept additional arguments, or you can pass the extra argument as a keyword argument.

TypeError: save_plot() takes 1 positional argument but 2 were given

这个错误提示意味着在调用save_plot()函数时，传递了两个参数，但是该函数只接受一个参数。可能的原因是在函数定义时没有正确地指定参数数量或者在调用函数时传递了多余的参数。你需要检查一下save_plot()函数的定义和调用，确保它们的参数数量匹配。如果你需要传递多个参数，可以考虑将它们打包成一个元组或字典，然后在函数内部进行解包。另外，你也可以考虑使用*args或**kwargs来接受任意数量的参数。

roc_display = RocCurveDisplay (X_test, y_test).plot() TypeError: RocCurveDisplay.__init__() takes 1 positional argument but 3 were given

这个错误信息表明你在尝试创建`RocCurveDisplay`对象时传入了额外的参数，而它的构造函数只接受一个位置参数。`RocCurveDisplay`可能是某个库（如scikit-learn）中的一个工具类，用于绘制ROC曲线，它通常需要测试数据（`X_test`和`y_test`）作为输入。

`RocCurveDisplay.plot()`是一个方法，可能用于显示已经计算好的ROC曲线。如果你想要正确地初始化这个对象，你需要确认是否按照类文档的说明提供了正确的参数。例如：

from sklearn.metrics import RocCurveDisplay

# 确保你只有一个参数实例化RocCurveDisplay
roc_curve = RocCurveDisplay(fpr=X_test[:, 0], tpr=y_test)
roc_curve.plot()

这里假设`X_test`和`y_test`分别包含特征和对应的标签，并且`fpr`代表false positive rate（假阳性率），`tpr`代表true positive rate（真阳性率）。如果有其他所需的属性或参数，请查阅相关库的官方文档。
