Issue following tutorial from video

[mickpires]

I'm following the youtube tutorial of syndy and I believe you need to update the tutorial code ( https://github.com/dynamicslab/pysindy/blob/master/examples/15_pysindy_lectures.ipynb ) because it seems feature_names isn't a parameter of SINDy class anymore. At least I had an error

---

TypeError Traceback (most recent call last)
Cell In[10], line 3
1 feature_names = ['x','y', 'z']
2 opt = ps.STLSQ(threshold=0)
----> 3 model = ps.SINDy(feature_names = feature_names, optimizer=opt)
4 model.fit(x_train, t = dt)
5 model.print()

TypeError: SINDy.init() got an unexpected keyword argument 'feature_names'

Well, I know it's a silly thing to report, but I believe it will make the tutorial better to follow.

I am getting the same thing right now, and if the feature_names is no longer part of expected usage, then the docs are outdated. So I think it might still be a useful issue.

[mickpires]

it seems the docs is outdated regarding this part because it cites that the parameter exists.

Yes, That notebook should be updated. The parameter has been moved from SINDy.__init__ to SINDy.fit, because its a data-dependent parameter.

The current plan was to break that notebook into smaller pieces, since it addresses several issues and it's hard to run a long notebook in CI. However, the youtube video has been a big draw and an important piece of the documentation. Maybe we need to think how to better redirect people to the appropriate documentation.
