我正在尝试删除自定义停用词列表，但它不起作用。
desc = pd.DataFrame(description, columns =['description'])
print(desc)
结果如下

我在这里找到了以下代码，但它似乎不起作用
remove_words = ["marijuana", "cannabis", "hemp", "thc", "cbd"]
pat = '|'.join([r'\b{}\b'.format(w) for w in remove_words])
desc.assign(new_desc=desc.replace(dict(string={pat: ''}), regex=True))
产生以下结果

处理案例，简化模式，
remove_words = ["marijuana", "cannabis", "hemp", "thc", "cbd"]
pat = '|'.join(remove_words)
desc['new_desc'] = desc.description.str.lower().replace(pat,'', regex=True)
