[BUG] Problem using ConstrainedSR3

[mickpires]

I'm following the youtube tutorial and it seems like ConstrainedSR3 isn't working. I searched in the repo and indeed there's a ConstrainedSR3 function, but when I try to use I get

36 )
37 model.fit(x_train_added_noise, t=dt, feature_names=feature_names)

I thought it was because it was inside the optimizers module. I tried to use ps.optimizers.ConstrainedSR3, but it didn't work as well.

I need some help

You need to install with the cvxpy extra, e.g. pip install pysindy[cvxpy]
