I'm a noob so please use laymen terms while supplying feedback. I have a coral mini dev board and after shelling in, updating, etc outlined here I start with the examples at the coral site. I follow instructions 1-3 here and then go to gstreamer and follow the instructions in that readme file. Each time building of lap fails. I have tried to pip install it on its own and end up with the same error. This is a brand new board and I have only followed the instructions to update and implement the example. Here is the error that I'm getting regardless of whether I bash install_requirements.sh or pip3 install lap:
mendel@green-orange:~/google-coral/example-object-tracker/gstreamer$ pip3 install lap

Thank you in advance
Can you run sudo apt-get install python3-dev and then retry the demo?
