How to Ingesting Data from .csv Files

[OodiOodiOodi]

My csv file data meets the requirements of the help document
date,open,high,low,close,volume,dividend,split
This is my extension.py code
import pandas as pd
from zipline.data.bundles import register
from zipline.data.bundles.csvdir import csvdir_equities

Define data time range

start_session = pd.Timestamp('2020-1-1', tz='UTC')
end_session = pd.Timestamp('2025-1-1', tz='UTC')

Register Bundle

register(
'my-csv-bundle',
csvdir_equities(
['daily'], # Data frequency (must be consistent with the subfolder name)
'C:/Users/86137/.zipline/data/mycsvs/daily',
),
calendar_name='SSE', # Exchange Calendar
start_session=start_session,
end_session=end_session
)
My program runs normally, but I don't have the corresponding bundle
