trying to read GeoJson File but I get this error message CPLE_OpenFailedError

Question

I'm trying to read a GeoJson file: acs2022_5yr_B01003_15000US060371198021.geojson

I downloaded the following libraries:

to read and visualize spatial data

import geopandas as gpd

to provide basemaps

import contextily as ctx

to give more power to your figures (plots)

import matplotlib.pyplot as plt

I saved the geojson in my folder (see path below): OneDrive/pscript/Practice_1/data/acs2022_5yr_B01003_15000US060371198021.geojson

Then I enter the following:

gdf = gpd.read_file('OneDrive/pscript/Practice_1/data/acs2022_5yr_B01003_15000US060371198021.geojson')

I get the following message: What does this mean?

Answer 1

As the error states: the file is not being found on the location you specify:

DriverError: OneDrive/pscript/Practice_1/data/acs2022_5yr_B01003_15000US060371198021.geojson:
No such file or directory

Note that you are using a relative path as it doesn't start with /. So the file will be searched starting from the "current directory" you are running it, which isn't always super transparent where that is. Best make it an absolute path.
