As always, you need to activate the virtual environment before running the example. If you haven't already then activate it like this.
source ~/venvs/blinka_venv/bin/activate
Next you can run the play_gif.py script.
python play_gif.py
The code for this example is embedded below. You can download it, or copy/paste the text into a file.
#!/usr/bin/python3
"""
Display an animated gif
Run like this:
$ python play_gif.py
The animated gif is played repeatedly until interrupted with ctrl-c.
