Command 'wal' not found

Hi, I'm new to Linux so installing some things can be pretty difficult. I'm new to Git too. I'm running i3wm using Regolith. I'm using Gnome with gnome-terminal. I installed the dependencies:

• python 3.5+ (I installed python3-pip, hope that's right)
• imagemagick (was already installed on my system)
• pidof (terminal said it was unable to locate package)
• feh (Installed fine)

I then installed pywal using the command pip3 install pywal

I typed this into my terminal to try it out. wal -i /home/szechuan/Pictures/Wallpapers/cool.jpg

but after that I got the error "Command 'wal' not found. Any help would be cool. I'm really new to all this so any beginner friendly responses would be cool. Thanks a lot. Pywal seems really cool & I'm looking forward to trying it out.
