hello: I am using ray for data index statistics, but I found that ray cannot modify the name of the index column like pandas. How should I deal with this situation? ![WechatIMG2134](https://us1.discourse-cdn.com/flex020/uploads/ray/original/2X/7/7eaa6257228c513f767a9c3c028e53caaa90235c.jpeg) ![WechatIMG2135](https://us1.discourse-cdn.com/flex020/uploads/ray/original/2X/6/6f33b3037fc1b1bcbfb3e12ad4913587971773da.jpeg) ---

Hi @839576266 - could you help provide an example code for Pandas? What you want to achieve in Ray Data? ---

Thank you for your reply. I want to use ray to realize the function of data indicator statistics, but when the data is saved, I find that ray Dataset cannot output a column with indicator names (such as sum and mean) like pandas ```auto import pandas as pd dict = {'x_0': [1, 2, 3], 'x_1': [4, 5, 6]} df = pd.DataFrame(dict) print(df.describe()) ``` ---

Hi @839576266 , currently when creating a Ray Dataset from an existing Pandas DataFrame ([ray.data.from\_pandas](https://docs.ray.io/en/latest/data/api/input_output.html#ray.data.from_pandas)), the resulting Dataset does not carry over the index column. For the code you are writing, is it a requirement that the indicator names from the Pandas DataFrame must stay in the index? Or is it possible to move it out into a column with [pd.DataFrame.reset\_index()](https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.reset_index.html)? If this is OK, then you could accomplish your desired result with something like: ```auto >>> import pandas as pd >>> dct = {'x_0': [1, 2, 3], 'x_1': [4, 5, 6]} >>> df = pd.DataFrame(dct) >>> df_summary = df.describe().reset_index() >>> df_summary index x_0 x_1 0 count 3.0 3.0 1 mean 2.0 5.0 2 std 1.0 1.0 3 min 1.0 4.0 4 25% 1.5 4.5 5 50% 2.0 5.0 6 75% 2.5 5.5 7 max 3.0 6.0 >>> import ray >>> ds_summary = ray.data.from_pandas(df_summary) >>> ds_summary.schema() PandasBlockSchema(names=['index', 'x_0', 'x_1'], types=[dtype('O'), dtype('float64'), dtype('float64')]) >>> ds_summary.take_all() [{'index': 'count', 'x_0': 3.0, 'x_1': 3.0}, {'index': 'mean', 'x_0': 2.0, 'x_1': 5.0}, {'index': 'std', 'x_0': 1.0, 'x_1': 1.0}, {'index': 'min', 'x_0': 1.0, 'x_1': 4.0}, {'index': '25%', 'x_0': 1.5, 'x_1': 4.5}, {'index': '50%', 'x_0': 2.0, 'x_1': 5.0}, {'index': '75%', 'x_0': 2.5, 'x_1': 5.5}, {'index': 'max', 'x_0': 3.0, 'x_1': 6.0}] ``` ---
