python - 使用时出现AttributeError；在 IBM Cloud Notebook 中插入代码 pandas DataFrame。该怎么办？

Question

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()
