python - Python bigquery lib 错误“pyarrow”没有属性“decimal256”

问题描述

AttributeError: module 'pyarrow' has no attribute 'decimal256' 似乎是 bigquery python 包的错误，应该如何处理？

整个堆栈是：

  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'

解决方案

我上周遇到了这个问题。我今天解决了这个问题。问题不在谷歌 API 中。问题出在pyarrow中。我只是将pyarrow包的版本更改为5.0.0版本（pyarrow==5.0.0），问题就解决了。
