[#]gischat Load a Qgis layer into a geopandas dataframe in the qgis python interpreter :

import pandas as pd

import geopandas as gpd

def layer_to_gdf(layer_name):

# PyQgisation of the layer

vlayer = QgsProject.instance().mapLayersByName(layer_name)[0]

attributes dataframe making

cols = [f.name() for f in vlayer.fields()]

datagen = ([f[col] for col in cols] for f in vlayer.getFeatures())

df = pd.DataFrame.from_records(data=datagen, columns=cols)

# generate GeoSeries
