返回空系列（Series（[]，名称：category，dtype：object）

Question

运行代码时，它适用于train_tags和打印 0培训数据 1个测试数据 名称：类别，dtype：对象

但是当我为test_tags运行相同的代码时，它给了我 系列（[]，名称：类别，dtype：对象）

完整代码如下：

---

path_train = r'C:\Users\Sgt.pookey01\Documents\Clickbait project\Article Titles'
files_train = skds.load_files(path_train,load_content=False)

---

files_train

{'文件名'：数组（['C：\ Users \ Sgt.pookey01 \ Documents \ Clickbait项目\ Article Titles \ TrainingData \ TrainingData.txt'， 'C：\ Users \ Sgt.pookey01 \ Documents \ Clickbait项目\ Article Titles \ TestingData \ TestingData.txt']， dtype ='

---

label_index = files_train.target
label_names = files_train.target_names
labelled_files = files_train.filenames

---

data_tags = ["filename","category","Article Titles"]

---

data_list = []
i=0
for f in labelled_files:
    data_list.append((f,label_names[label_index[i]],Path(f).read_text(encoding="utf-8")))
    i += 1

---

 data = pd.DataFrame.from_records(data_list, columns=data_tags)

---

train_size = int(len(data['Article Titles'][0])*.8)
train_posts = data['Article Titles'][:train_size]
train_tags = data['category'][:train_size]
train_files_names = data['filename'][:train_size]

train_tags

0培训数据 1个测试数据 名称：类别，dtype：对象

test_posts = data['Article Titles'][train_size:]
test_tags = data['category'][train_size:]
test_files_names = data['filename'][train_size:]

test_tags

Series（[]，名称：category，dtype：object）
