Drawing the trajectory path

[camillerievan]

I managed to draw the trajectory path of my minimization function on the 2D graph - how can I do the same on the 3D graph?

Hey @camillerievan, you can try to get the 2D trajectory as usual, and then create a new list with the corresponding loss values, lets call them z. You should be able to plot the line via something like
ax.plot(x, y, zs=z)
where ax is your 3D axis, x and y are your 2D projection coordinates.

In short, you can plot on a 3D surface just like you would on any matplotlib 3D axis.
