我尝试在 jupyter notebook 上的 python 2.7 中实现 bigquery。我认为我的代码是正确的，但我收到错误“AttributeError：'Client' object has no attribute 'query'”

# Create SQL query using natality data after the year 2000
query = """
SELECT
  weight_pounds,
  is_male,
  mother_age,
  plurality,
  gestation_weeks,
  ABS(FARM_FINGERPRINT(CONCAT(CAST(YEAR AS STRING), CAST(month AS STRING)))) AS hashmonth
FROM
  publicdata.samples.natality
WHERE year > 2000
"""

# Call BigQuery and examine in dataframe
from google.cloud import bigquery
client = bigquery.Client()
df = client.query(query + " LIMIT 100").to_dataframe()
df.head()

我得到的错误信息是：

AttributeErrorTraceback (most recent call last)
<ipython-input-12-caf57b3f137d> in <module>()
      2 from google.cloud import bigquery
      3 client = bigquery.Client()
----> 4 df = client.query(query + " LIMIT 100").to_dataframe()
      5 df.head()

AttributeError: 'Client' object has no attribute 'query'

问题已解决！只需要通过更新 bigquery pip install --upgrade google-cloud-bigquery
