根据错误堆栈信息,问题出现在你的代码的 `farmer_view.py` 文件的第 181 行,尝试访问一个名为 `finder_income.objects.all()` 的属性,但该函数对象并没有该属性。这个错误通常发生在尝试在一个函数对象上访问一个不是模型类的属性。
要解决这个问题,你需要确认在代码的其他地方是否导入并定义了名为 `finder_income` 的模型类。检查一下导入的模块和相关的依赖是否正确导入和安装。另外,请确保你使用正确的模型类来访问 `objects` 属性。
如果可能的话,请提供 `farmer_view.py` 文件的相关代码,以便我可以更详细地帮助你解决问题。

这个错误通常是由于训练数据中存在非数字字符导致的。具体来说,在这个错误中,训练数据中的某些值包含字符串 "40-80",这是一个包含破折号的字符串,无法被正确地转换为浮点数。为了解决这个问题,您需要仔细检查您的训练数据,找出所有包含非数字字符的值,并将其转换为数字类型。您可以使用 Pandas 库中的 replace 方法将破折号替换为句点,然后将整个数据集转换为浮点数类型。例如,您可以使用下面的代码将 "40-80" 替换为 "40.80":
```
df.replace("40-80", "40.80", inplace=True)
df = df.astype(float)
```
这将把包含 "40-80" 的所有值替换为 "40.80",然后将整个数据集转换为浮点数类型。

这个错误可能是因为你使用的 Python 版本不兼容 configparser 模块。你可以尝试使用 Python 3.5 或更高版本来安装 configparser 模块。你可以尝试在命令行中输入以下命令来安装 configparser 模块:
```
pip3 install configparser
```
如果你已经安装了多个 Python 版本,你需要确保使用正确的 pip 和 python 版本来安装 configparser 模块。
