Second code block in "Example of minimally complex ESN" appears not to work #226

Something isn't working

It seems here the errors stem from two different things:
Regarding 1. I think I'll need some help here (pinging @ChrisRackauckas ), regarding 2. let me sketch a quick working example with the new API: the first block also a slight change, using using PredefinedDynamicalSystems
train_len = 3000
predict_len = 2000
ds = Systems.henon()
traj, t = trajectory(ds, 7000)
data = Matrix(traj)'
data = (data .-0.5) .* 2
shift = 200
training_input = data[:, shift:shift+train_len-1]
training_target = data[:, shift+1:shift+train_len]
testing_input = data[:,shift+train_len:shift+train_len+predict_len-1]
testing_target = data[:,shift+train_len+1:shift+train_len+predict_len]The second block looks goes as follows: using ReservoirComputing, StatsBase
res_size = 300
input_layer = [minimal_init(; weight = 0.85, sampling_type=:irrational),
minimal_init(; weight = 0.95, sampling_type=:irrational)]
reservoirs = [simple_cycle(; weight=0.7),
cycle_jumps(; cycle_weight=0.7, jump_weight=0.2, jump_size=5)]
for i=1:length(reservoirs)
esn = ESN(training_input, 2, res_size;
input_layer = input_layer[i],
reservoir = reservoirs[i])
wout = train(esn, training_target, StandardRidge(0.001))
output = esn(Predictive(testing_input), wout)
println(msd(testing_target, output))
endbut this will not work until #227 is merged, I found a little problem in the implementation of the minimal reservoirs that needed fixing. I will also take the opportunity to add this example to the docs again so I'll leave this issue open. In the meantime you can |

Describe the bug 🐞
Executing the second block of code in the documentation, throws unexpectedly an error.
