Python bigquery lib 错误'pyarrow'没有属性'decimal256'

Question

AttributeError:模块'pyarrow'没有'decimal256'属性似乎是一个错误的bigquery python包，应该如何处理?

整个栈是:

File "/opt/conda/default/lib/python3.7/site-packages/google/cloud/bigquery/__init__.py", line 35, in <module>
from google.cloud.bigquery.client import Client
File "/opt/conda/default/lib/python3.7/site-packages/google/cloud/bigquery/client.py", line 70, in <module>
from google.cloud.bigquery import _pandas_helpers
File "/opt/conda/default/lib/python3.7/site-packages/google/cloud/bigquery/_pandas_helpers.py", line 151, in <module>
pyarrow.decimal256(76, scale=38).id: "BIGNUMERIC",
AttributeError: module 'pyarrow' has no attribute 'decimal256'

Answer 1

我上周就遇到了这个问题。我今天解决了。问题不在于谷歌API。问题出在pyarrow。我只是把pyarrow包的版本改为5.0.0版本(pyarrow==5.0.0)，问题就解决了。
