问题描述

我尝试在终端和juypter实验室中安装它，并说它已经成功安装，但是当我运行df = query_job.to_dataframe()时，我一直收到错误消息 ValueError:未安装pyarrow库，请安装pyarrow以使用to_arrow()函数.".我不知道该如何解决.有什么建议吗?我试图最终使用代码从Google Data Studio访问数据，

I have tried installing it in the terminal and in juypter lab and it says that it has been successfully installed but when I run df = query_job.to_dataframe() I keep getting the error " ValueError: The pyarrow library is not installed, please install pyarrow to use the to_arrow() function.". I have no idea how to fix this. Any advice? I am trying to access data from google data studio ultimately with the code,

from google.cloud import bigquery
import pandas
import numpy
import pyarrow
bigquery_client = bigquery.Client()
import os 
os.environ['GOOGLE_APPLICATION_CREDENTIALS'] ='full file path here.json'
QUERY = """
SELECT * 
FROM `warehouse`
LIMIT 100
"""
query_job = bigquery_client.query(QUERY)
df = query_job.to_dataframe()

推荐答案

我遇到了同样的问题，因为我有pyarrow 2.0，但是您将需要版本1.0.1. 尝试运行以下行:pip install pandas-gbq == 0.14.0
