python - 在 AI-Platform-Notebooks 中使用 BigQuery 的 ContextualVersionConflict

Question

我正尝试在 AI-Platform-Notebooks 中使用 BigQuery，但遇到了 ContextualVersionConflict。在这个玩具示例中，我试图从项目 job2vec 中名为 bgt_all 的 BigQuery 数据库中提取两列数据。

from google.cloud import bigquery

client = bigquery.Client()

aaa="""

SELECT BGTJobId, soc6 FROM `job2vec.bq_bgt_storage.bgt_all` LIMIT 100
"""
df = client.query(aaa).to_dataframe()
df.head()

返回

这很奇怪，因为当我运行时!pip 安装 google-api-core --upgrade它显示它是 1.24.1，所以我不太明白为什么。

Answer 1

为了进一步为社区做出贡献，我根据上面的评论发布了答案。

首先，您应该尝试使用以下命令升级软件包:

pip install --upgrade pandas-gbq 'google-cloud-bigquery[bqstorage,pandas]'

然后，您可以使用 read_gbq() 而不是使用 to_dataframe() 方法，它使用环境的默认项目从 BigQuery 加载数据，如下所示:

import pandas

sql = """
    SELECT name
    FROM `bigquery-public-data.usa_names.usa_1910_current`
    WHERE state = 'TX'
    LIMIT 100
"""

# Run a Standard SQL query using the environment's default project
df = pandas.read_gbq(sql, dialect='standard')

# Run a Standard SQL query with the project set explicitly
project_id = 'your-project-id'
df = pandas.read_gbq(sql, project_id=project_id, dialect='standard')
