BadZipFile: File is not a zip file

[GKG1312]

Hi,
I was following Earth lab's Intro to earth data science textbook and in Section 2, chapter-5 while running the codes for vector files, I am getting BadZipFile errors. This problem seems to be with all files from the Natural Earth webpage. I am able to download the zip file separately but using get_data function is giving an error.
Here is the code I am running:

# Import packages
import os
os.environ['USE_PYGEOS'] = '0'
import matplotlib.pyplot as plt
import geopandas as gpd
import earthpy as et

link = 'https://www.naturalearthdata.com/http//www.naturalearthdata.com/download/50m/cultural/ne_50m_admin_0_boundary_lines_land.zip'
# Download the data and set working directory
et.data.get_data(url=link)

# Set working directory - earthpy creates earth-analytics for you in your home dir
os.chdir(os.path.join(et.io.HOME, 'earth-analytics'))

I am getting following error:

Downloading from https://www.naturalearthdata.com/http//www.naturalearthdata.com/download/50m/cultural/ne_50m_admin_0_boundary_lines_land.zip

BadZipFile: File is not a zip file

Hope this will be helpful for you in solving the issue.
Thank you

Hi Girish - thanks for the message.

It looks like naturalearthdata changed their download so that we can't use the same url anymore when downloading in Python (as opposed to the browser which still works fine). We're working on getting in touch with them so that we can get direct download lines. In the meantime, you can download from naturalearthdata in the browser and move the data into your earthpy-downloads folder under the path the code is looking for.

We'll update here when we have a permanent solution!
