You should not name your file name as geopandas.py. From the traceback of from geopandas import GeoSeries, GeoDataFrame, we can know that the file name you are using is geopandas.py and it makes Python import this file rather than the geopandas module. Change this file at the following path to other names and it should work.

from geopandas import GeoSeries, GeoDataFrame

File "C:\Users\XXXXX\Documents\Python_Scripts\geopandas.py", line 1, in <module>

                                            ---------------

It seems that it wasn't too complicated : I removed geopandas, but this time I closed Spyder and Anaconda and then re-opened them, and I've could then reinstall it effectively !

Just updating if happenns to someone: In the end what worked for me was to uninstall and install again geopandas and pyproj

Updating system's libjpeg broke the dynamic linking of fiona. There are two ways to deal with that:

I would prefer: pip uninstall fiona, conda install fiona

If you want to stick with pip: pip uninstall fiona, pip install fiona

For a more detailed explanation, also see my answer here:

import matplotlib.pyplot gives ImportError: dlopen(…) Library not loaded libpng15.15.dylib

See my comment in Fiona's issue tracker: https://github.com/Toblerity/Fiona/issues/986

GDAL (the library Fiona uses to access the geodata) maintains an iterator over the features that are currently read. There a some operations that, for some drivers, can influence this iterator. Thus, after such operations we have to ensure that the iterator is set to the correct position that a continuous read of the data is ensured. Such operations include counting all features in a dataset, respectively calculating its extent.

There are different types of drivers in GDAL. Some drivers support random access, while some do not. For the drivers that do not support random access, the resetting of the iterator involves reading all features again up to the iterator position. As this is a possible costly operation, this RuntimeWarning is emitted, so that users are aware of this behavior.

That way of merging is creating a Pandas DataFrame. Try this:

import geopandas as gpd

df = gpd.read_file(r"/home/bera/Drives/data1/data/LMV/LMV-data_2021-10/ok_riks_Sweref_99_TM_shape/oversikt/riks/ak_riks.shp")

gdf1 = df.head(10)
gdf2 = df.tail(10)

print(type(gdf1.merge(gdf2, on="LANSKOD", how="outer"))) #This is creating a pandas df
#pandas.core.frame.DataFrame

merged = gpd.pd.merge(gdf1, gdf2, on="LANSKOD", how="outer")
print(type(merged))
#<class 'geopandas.geodataframe.GeoDataFrame'> #Now it is a geopandas df

merged["geometry"] = merged["geometry_x"].combine_first(merged["geometry_y"]) #Create a complete geometry column
merged = merged.drop(columns=["geometry_x", "geometry_y"])
merged.to_file(r"/home/bera/Desktop/GIStest/testmerge.shp")

If you don't select geometry column from a GeoDataFrame, you get a DataFrame.

For example:

print type(trialyield[['column1', 'column2']])
# OUT:
# pandas.core.frame.DataFrame

print type(trialyield[['column1', 'column2', 'geometry']])
# OUT:
# geopandas.geodataframe.GeoDataFrame

Change the last line in following way:

trialyield[[title_col, 'yield', 'geometry']].to_file('trialyield_output.shp')

Does the issue present its self with other shapefiles too or just this one? I'm running geopandas 2.1.0 and fiona 1.7.3 and can't reproduce the issue w/ any files I have. Maybe you should try updating fiona?

I like to run this nifty little script every so often. It takes a little while to run but it will update every package you have installed.

import pip
from subprocess import call

for dist in pip.get_installed_distributions():
    call("pip install --upgrade " + dist.project_name, shell=True)
    print (dist.project_name)
