当我在 watson studios 中使用“查找和添加数据”功能将 CSV 文件加载到我的笔记本中时，我遇到了问题。当我使用“插入代码”时，我得到了自动代码行，以将 CSV 文件转换为 pandas 数据框。

它似乎以某种方式加载数据，但它仍然给出以下错误。我没有对生成的默认代码进行任何更改。这里发生了什么？

import os, types
import pandas as pd
from botocore.client import Config
import ibm_boto3

def __iter__(self): return 0

if os.environ.get('RUNTIME_ENV_LOCATION_TYPE') == 'external':
    endpoint_xxx = 'https://s3.eu.cloud-object-storage.appdomain.cloud'
else:
    endpoint_xxx = 'https://s3.private.eu.cloud-object-storage.appdomain.cloud'

client_xxxxx = hidden

body = client_xxx.get_object(Bucket='xxx',Key='xxx.csv')['Body']

# add missing __iter__ method, so pandas accepts body as file-like object
if not hasattr(body, "__iter__"): body.__iter__ = types.MethodType( __iter__, body )

df_data_1 = pd.read_csv(body, sep=';')
df_data_1.head()
