bug: Missing attribute: WKTReader #1364
Description
An issue that appears to be in this library popped up while running a test in a related bigquery library.
.nox/prerelease/lib/python3.8/site-packages/google/cloud/bigquery/table.py:46: in <module>
_read_wkt = shapely.geos.WKTReader(shapely.geos.lgeos).read
E AttributeError: module 'shapely.geos' has no attribute 'WKTReader'
Based on a quick review, it appears that shapely.geos no longer has a WKTReader class and it appears that the WKTReader class has been removed from the library entirely and they might be relying on a function elsewhere in the codebase. If I had to wager a guess, I might look at the from_wkt method in io.py.

I am still experiencing this issue with
from google.cloud import aiplatformandfrom vertexai import preview. I am using the latest version of shapely.tomaxberg commentedon Nov 16, 2023
Try reinstall packages bs4, docarray, tiktoken, and streamlit. This worked for me.

@tparkerNYT
In looking at your tracebacks, they show line 46 in the file
google/cloud/bigquery/table.pyas:_read_wkt = shapely.geos.WKTReader(shapely.geos.lgeos).readStarting in version 3.3.6 of
python-bigquery, code was inserted that began to refer to objects inshapelyby their current nomenclature instead of referencingWKTReader.If you upgrade your version of
python-bigquery, it should fix this issue.Gonna leave this issue closed and close out the related one in the
pubsublibrary
