when using polars.dataframe, it sometimes displays dots instead of actual datas. i dont know what im missing.(have no problem when using pandas). can can you tell me what i should do?

import polars as pl 
import pandas as pd

class new:
    xyxy = '124'

a = [[[0.45372647047042847, 0.7791867852210999, 0.05796612799167633,

Use polars.Config.set_tbl_rows to control the number of displayed rows:

pl.Config.set_tbl_rows(1000)
print(new.xyxy[0])

# Output
shape: (9, 7)
