Data Frame to Excel - AttributeError: 'Series' object has no attribute 'columns'

Question

我正在尝试将数据帧写入 Excel 文件。这在过去对我有用，但这次，它给了我一个 AttributeError.

代码

我有一个名为 data 的数据框，如下所示：

我把它放到这段代码中：

# To find tf-idf values
textVal = data.text.values.astype('str')
vectorizer = TfidfVectorizer()
vectorizer.fit(textVal)
X = vectorizer.transform (textVal).toarray()
names = vectorizer.get_feature_names()
tfidf_dataframe = pd.DataFrame(X, columns = names)

# To print TF-IDF
writer = pd.ExcelWriter('tfidf_test.xlsx', engine='xlsxwriter')
tfidf_dataframe.to_excel(writer)
writer.save()
print("complete")

tfidf_dataframe 看起来像这样：

关于我收到此错误消息的原因有什么想法吗？

Answer 1

您确定您是从运行那里得到的吗？你的回溯似乎暗示它不是。

     14 # To print TF-IDF
---> 15 tfidf_dataframe.to_excel(writer)
     16 
     17 # To print sentiment analysis

# To print TF-IDF
writer = pd.ExcelWriter('tfidf_test.xlsx', engine='xlsxwriter')
tfidf_dataframe.to_excel(writer)
writer.save()
print("complete")

我相信默认引擎已经是 xlsxwriter，所以你也可以只做 tfidf_dataframe.to_excel('tfidf_test.xlsx')

我的预感之一可能是，如果此代码存在于模块中，那么您正在积极开发它并且您没有将它重新导入到您的 Jupyter 环境中。

如果是这样，请尝试：

import importlib
importlib.reload(module)

其中 module 是您的代码所在模块的名称。
