sample_submission.csv中边界框这一列格式为a b c d,a,b,c,d在0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9九个数中随机,用python随机将a b c d这组数填入sample_submission.csv中边界框这一列

sample_submission.csv
在Python中,你可以使用`pandas`库操作CSV文件,并利用`random`模块生成随机数。首先,确保已经安装了`pandas`,如果没有,可以运行`pip install pandas`。
下面是一个简单的示例,说明如何在`sample_submission.csv`中替换边界框(通常表示为左上角(x, y)和右下角(w, h)的四个值):
```python
import pandas as pd
import random
# 假设df是DataFrame对象,代表读取的sample_submission.csv文件
if not isinstance(df, pd.DataFrame):
df = pd.read_csv('sample_submission.csv')
# 定义九个可能的坐标范围
boundaries = [(0.1, 0.1), (0.2, 0.2), ..., (0.9, 0.9)]
# 创建一个新的列来存储边界框,格式为'a b c d'
df['new_bbox'] = df.apply(lambda row: f"{random.choice(boundaries)[0]} {random.choice(boundaries)[1]} {random.choice(boundaries)[0] + random.choice(boundaries)[2]} {random.choice(boundaries)[1] + random.choice(boundaries)[3]}", axis=1)
# 保存修改后的数据
df.to_csv('sample_submission_with_random_bboxes.csv', index=False)
