You have two options here: * One thing you can do is run in Google Colab, you will not have problems there. * Another, you should add the following code after targets = targets.reshape(observations,) and before ax.plot(xs, zs, targets) to reshape xs to (observations,): xs = xs.reshape(observations,) and add the following code after targets = targets.reshape(observations,1) to reshape it back: xs = xs.reshape(observations,1)
