这是一段SQL查询语句，大致意思是根据一些条件过滤出符合要求的商品，然后统计出每个商家销售的该商品的数量。最后再将这些信息与商家名称、商品名称等信息一起查询出来。

具体来说，这个查询语句先用一个子查询过滤出类型为1的商品，然后在orders表和order_goods表中根据一些状态条件和商品型号条件筛选订单，统计出每个商家销售的每个商品数量，最后通过JOIN操作连接base_goods表和merchant表，查询出商品名称、市场时间、商家名称等信息。

根据你之前的说明，应该是将第5行的代码从：

model = load_model('model.h5')

改为：

model = None

这样就可以重新声明一个没有用的 `model` 变量了。

你需要将 `y_pred_filtered` 数组转换为 pandas DataFrame，然后再使用 `drop_duplicates()` 方法进行去重。你可以使用 `pd.DataFrame()` 将 numpy 数组转换为 DataFrame，如下所示：

import pandas as pd
import numpy as np
# ... 其他代码 ...

# 对 y_pred 进行过滤和去重
row_sums = np.sum(y_pred, axis=1)
y_pred_filtered = y_pred[(row_sums >= 6) & (row_sums <= 24), :]
y_pred_filtered_df = pd.DataFrame(data=y_pred_filtered, columns=data.columns[:8])
y_pred_filtered_df.drop_duplicates(inplace=True)

# 打印预测结果
print('Predicted values with probabilities:')
print(y_pred_filtered_df)

这应该可以解决你遇到的问题。
