valuation Pretrained models from the model zoo can be evaluated using the `eval.py` script. For example, the model on cifar-10 can be evaluated as follows: ```shell python eval.py --config_exp configs/scan/scan_cifar10.yml --model $MODEL_PATH ``` Visualizing the prototype images is easily done by setting the `--visualize_prototypes` flag. For example on cifar-10: <p align="center"> <img src="images/prototypes_cifar10.jpg" width="600" /> </p> Similarly, you might want to have a look at the clusters found on ImageNet (as shown at the top). First download the model (link in table above) and then execute the following command: ```shell python eval.py --config_exp configs/scan/wjd_eval.yml --model $MODEL_PATH_IMAGENET ```，这段话说了啥，能解释一下吗

这段话是在介绍如何使用预训练模型进行评估和可视化。预训练模型可以从模型库中获取。以CIFAR-10为例，可以使用以下命令进行评估：```shell python eval.py --config_exp configs/scan/scan_cifar10.yml --model $MODEL_PATH```。如果需要可视化原型图像，只需设置`--visualize_prototypes`标志即可。例如，在CIFAR-10上，可以使用以下命令进行可视化：```shell python eval.py --config_exp configs/scan/wjd_eval.yml --model $MODEL_PATH_IMAGENET```。同样，如果需要查看在ImageNet上找到的聚类结果，则需要先下载该模型（链接在上述表格中），然后执行以上命令。

详细举例This code represents a class named "PropertyManagementCompany" which manages a portfolio of real estate properties. The class has a name, liquidity and a set of properties that it manages. The liquidity represents the amount of money the company has available to purchase new properties or sell existing ones. The class has two constructors, one that creates an empty portfolio and sets the liquidity to zero, and another that takes a list of properties and adds them to the portfolio. Both constructors also require the company name and liquidity as parameters. The class has two methods to buy and sell real estate properties. The "buyProperty" method takes a property and a purchase price as parameters and adds the property to the portfolio if the company has enough liquidity to buy it. The "sellProperty" method takes a property and removes it from the portfolio while adding the property's current valuation to the company's liquidity. The class also has getters for the name, liquidity, and portfolio. The "checkName" method is a private helper method that checks if the company name is empty and throws an exception if it is. Overall, this code uses encapsulation to hide the implementation details of the PropertyManagementCompany class. The class has private fields that can only be accessed through its public methods. This approach makes the code more modular and easier to maintain.

class PropertyManagementCompany:
    def __init__(self, name, liquidity, properties=None):
        self.checkName(name)
        self.name = name
        self.liquidity = liquidity
        if properties is None:
            self.portfolio = []
        else:
            self.portfolio = properties

    def buyProperty(self, property, purchasePrice):
        if self.liquidity >= purchasePrice:
            self.portfolio.append(property)
            self.liquidity -= purchasePrice

    def sellProperty(self, property):
        if property in self.portfolio:
            self.portfolio.remove(property)
            self.liquidity += property.currentValuation

    def getName(self):
        return self.name

    def getLiquidity(self):
        return self.liquidity

    def getPortfolio(self):
        return self.portfolio

    def checkName(self, name):
        if name == '':
            raise ValueError('Company name cannot be empty.')

For example, we can create a new PropertyManagementCompany as follows:

properties = [Property('123 Main St.', 100000), Property('456 Oak Ave.', 200000)]
company = PropertyManagementCompany('ABC Company', 500000, properties)

This creates a company named "ABC Company" with $500,000 liquidity and a portfolio containing two properties. We can then buy a new property and sell an existing property using the `buyProperty` and `sellProperty` methods:

newProperty = Property('789 Elm St.', 150000)
company.buyProperty(newProperty, 150000)

propertyToSell = properties[0]
company.sellProperty(propertyToSell)

This would add the new property to the portfolio and remove the first property from the portfolio while adding its current valuation to the company's liquidity.

这是一个追溯（Traceback）错误，通常用于指示程序执行出错的地方。这个错误信息告诉我们，在文件 "MC_LimitAutocall.py" 的第 66 行上发生了一个语法错误。具体来说， "return" 关键字被放在函数外部，这是不允许的。这通常是因为程序员错误地将 return 语句放在了函数之外，或者没有正确地定义一个函数。你需要检查代码，确保 return 语句被正确地放置在函数内部，并且函数被正确地定义。
