这个错误是由于数据集中不存在名为 `income` 的列引起的。在第14行中，代码使用 `data.drop('income', axis=1)` 删除了目标变量 `income` 后的数据集作为训练集和测试集的特征集，但是在第18行中，代码又尝试去访问 `data['income']` 进行二元编码，从而引发了 KeyError 错误。建议在进行数据集划分前，先检查数据集中是否存在目标变量 `income`，例如使用 `print(data.columns)` 查看数据集中包含哪些列。

这个错误提示是因为连接MySQL数据库时，用户名或密码不正确，你需要检查一下你的用户名和密码是否正确。同时，也需要确保你的MySQL服务器已经启动，并且允许远程连接。

如果你忘记了MySQL的用户名和密码，可以尝试使用以下命令来重置密码：

1. 停止MySQL服务

sudo service mysql stop

2. 以跳过授权方式启动MySQL

sudo mysqld_safe --skip-grant-tables --skip-networking &

3. 使用root用户登录MySQL

mysql -u root

4. 切换到mysql数据库

use mysql;

5. 更新root用户的密码

update user set authentication_string=password('your_new_password') where user='root' and Host ='localhost';

6. 刷新权限

flush privileges;

7. 退出MySQL并重新启动服务

exit;
sudo service mysql start

然后，你可以使用新的密码来连接你的MySQL数据库了。
