问题描述

我尝试在终端和 juypter 实验室中安装它，它说它已成功安装，但是当我运行 df = query_job.to_dataframe() 时，我不断收到错误;ValueError: pyarrow 库未安装，请安装 pyarrow 以使用 to_arrow() 函数.".我不知道如何解决这个问题.有什么建议吗?我试图最终使用代码从谷歌数据工作室访问数据，

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

我在测试 Python 代码时收到相同的错误消息 ModuleNotFoundError: No module named 'pyarrow'.使用 pip install pyarrow 安装 pyarrow 依赖项后，此行为消失.

I got the same error message ModuleNotFoundError: No module named 'pyarrow' when testing your Python code. This behavior disappeared after installing the pyarrow dependency with pip install pyarrow.

在运行 pip install pyarrow
