Error: Points of LinearRing do not form a closed linestring

[jrdalenberg]

I was trying out this tool and ran into an error in the polygons.parquet file.

Inference ran successfully

I tried reading the data with Geopandas

import geopandas as gpd
data = gpd.read_parquet("results/polygons.parquet")

It gives me the following error:

File ~/miniconda3/envs/turing_segment/lib/python3.10/site-packages/shapely/io.py:353, in from_wkb(geometry, on_invalid, **kwargs)
    349 # ensure the input has object dtype, to avoid numpy inferring it as a
    350 # fixed-length string dtype (which removes trailing null bytes upon access
    351 # of array elements)
    352 geometry = np.asarray(geometry, dtype=object)
--> 353 return lib.from_wkb(geometry, invalid_handler, **kwargs)

GEOSException: IllegalArgumentException: Points of LinearRing do not form a closed linestring

My best guess is that a polygon shape validation is missing before saving the data to disk.

Versions:
shapely: 2.1.1
geopandas: 1.1.1
turing_segment: 0.3.9

Hi！Have you successfully run "pip install -U turing_segment"?
When i was tried to run this command, the Anaconda prompt returned:
"ERROR: Could not find a version that satisfies the requirement turing_segment (from versions: none)
ERROR: No matching distribution found for turing_segment"
