polars.dataframe 有时显示点而不是数据

Question

使用polars.dataframe时，有时会显示点而不是实际数据。我不知道我缺少什么。（使用 pandas 时没问题）。你能告诉我应该怎么做吗？

import polars as pl 
import pandas as pd

class new:
    xyxy = '124'

a = [[[0.45372647047042847, 0.7791867852210999, 0.05796612799167633,

ca = 'xmin', 'ymin', 'xmax', 'ymax', 'confidence', 'class', 'name'  # xyxy columns
cb = 'xcenter', 'ycenter', 'width', 'height', 'confidence', 'class', 'name'  # xywh 
columns

for k, c in zip(['xyxy', 'xyxyn', 'xywh', 'xywhn'], [ca, ca, cb, 
cb]):
    setattr(new, k, [pl.DataFrame(x, columns=c, orient="row") for x in a])
    #setattr(new, k, [pd.DataFrame(x, columns=c, orient="row") for x in a]) 

print (new.xyxy[0])

Answer 1

使用polars.Config.set_tbl_rows控制显示行数：

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

# Output
shape: (9, 7)
