To use gdal in Python, you need to install the gdal packages on your computer.
Unfortunately, that is operating system dependent.
Use brew to do this. First, install homebrew:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
If you get the warning:
Warning: /usr/local/bin is not in your PATH.
We assume the shell you use is bash, but it may be something different like zsh (especially on OS X). You should be able to check your shell with:
echo $SHELL
If is gives /bin/bash, then you are using bash, if it gives something else like /bin/zsh then you may need to change ~/.bash_profile to ~/.zsh_profile.
Then type the following:
echo 'PATH="/usr/local/bin:${PATH}"' >> ~/.bash_profile
and open a new shell.
Then get gdal:
Install the headers files first to avoid GDAL fail.
brew install gdal --HEAD
Then
brew install gdal
Check the install with:
gdal-config --version
which should give e.g.
2.4.4
If you hit problems, read what it says and respond accordingly. For OS X for example, you may need to install xcode command line tools if you don't already have that. N.B. That might take some time. You might also look at this advice page
For Windows, if you use WSL-Windows System for Linux, then you should be able to install and use brew as above. There is a good tutorial for that here. If you use this though, you need to also install all of the packages in WSL and run jupyter from there. There is a good tutorial on that here.
Otherwise, you might try some advice from the web.
