Trying to read a shapefile (.shp) and received an ImportError after executing the below line of code. I even pip installed GDAL, geopandas, fiona and shapely before executing the below code.
shapefile = gpd.read_file(r'C:\Users\....\Data Analysis\shapefiles\louisville.shp')
Error received is as follows,

Apparently, I was using below versions of GDAL and fiona combinations which didn't work for me.
GDAL-3.3.2-cp38-cp38-win_amd64.whl
Fiona-1.8.20-cp38-cp38-win_amd64.whl
I had to uninstall the above versions and install the below versions instead. This resolved the issue.
GDAL-3.2.3-cp38-cp38-win_amd64.whl
Fiona‑1.8.19‑cp38‑cp38‑win_amd64.whl
I stumbled upon the same problem. I was able to address the issue by creating a new environment in python 3.7 and downgrading the gdal package.
With Conda Forge, after installing geopandas, I downgraded gdal to version 2.3.3 and accepted the dependency changes suggested by anaconda. Eventually I ended up with the following versions:
python 3.7.11
geopandas 0.6.1
gdal 2.3.3
fiona 1.8.4
Within Conda Forge, I force uninstalled both GDAL and Fiona, then installed Fiona 1.8.19 as suggested by Abhiram. Conda Forge installed GDAL 3.2.2 as part of this process, and the two seem to work together well.
