CRSError: Invalid projection: EPSG:4326

Hi, I’m working in a jupyter notebook and trying to specify the CRS of a geopandas dataframe, like so:

import geopandas as gpd
import pyproj
coords = df[['latitude','longitude']]
raw_gpspoints_gdf = gpd.GeoDataFrame(
    coords, geometry=gpd.points_from_xy(coords['longitude'], coords['latitude']), crs="EPSG:4326")

However, every time I get the error:

CRSError: Invalid projection: EPSG:4326: (Internal Proj Error: proj_create: SQLite error on SELECT name, type, coordinate_system_auth_name, coordinate_system_code, datum_auth_name, datum_code, area_of_use_auth_name, area_of_use_code, text_definition, deprecated FROM geodetic_crs WHERE auth_name = ? AND code = ?: no such column: area_of_use_auth_name)

My versions are:

import sys
import pyproj
import geopandas
print(sys.version)
print(pyproj.__version__)
print(geopandas.__version__)

3.8.6 | packaged by conda-forge | (default, Oct  7 2020, 19:08:05) 
[GCC 7.5.0]
2.6.1.post1
0.8.1

and my pyproj directory is

pyproj.datadir.get_data_dir()

'/opt/conda/lib/python3.8/site-packages/pyproj/proj_dir/share/proj'

How do I resolve this issue?

This is an issue with pyproj package. They even cover this exact error in their documentation: https://pyproj4.github.io/pyproj/stable/gotchas.html#internal-proj-error-sqlite-error-on-select. Your pyproj points to a database created for a different version. You need to specify the path to a correct data directory (see the docs). Proper reinstallation also often helps.

Specifically in your case, it seems that you installed pyproj using pip (as a wheel, because it looks for PROJ data inside the pyproj package), and not with conda (although you are using a conda environment). It’s best to install all those packages with conda (especially for non-pure python packages such as pyproj)
