‫Welcome back.
‫So let's now install QB solvers.
‫If you use Linux Ubuntu, if you Google QB solvers, then this first result here, it shows you the
‫instructions for the solver.
‫So if you click on it, then you can see that this GitHub is managed by Stephanie Curran.
‫Here you can see installation and here you can see the structure of the QB solvers.
‫You've seen that in the previous section as well.
‫And then here you also have an example.
‫You can later put it in Python and then see how it works.
‫And so in order to install it for Linux Ubuntu, that's actually very easy.
‫In terminal, you have to run these two commands.
‫And so I open my terminal.
‫I copy the first line here.
‫I press enter.
‫Then you have to put your password here, the one that you use in order to log in to your Linux Ubuntu
‫operating system.
‫And once it is done, you write pip three, install cube solvers and there you go.
‫Succesfully installed cube solvers.
‫I will then go into the folder where I have my python simulation.
‫Now I'm inside that folder and then I write Python three and then the main file.
‫But remember inside this folder, you also need to have your support file.
‫So before I run it, I'll just write here.
‫LS And so you can see that this is my main file here.
‫And this is my support file.
‫And so I'm going to run my file.
‫My main file is going to take some time.
‫And there you go.
‫It works.
‫Of course, it's a little bit slow now, but that's because I'm running the animation and recording
‫the screen at the same time.
‫And here you have the plot of the trajectory, and that's it.
‫You have copy solvers for Linux Ubuntu.
‫Thank you very much.
