Hi I am having errors while using SINDy-PI, i am using for implicit ODE

Hi, I am having issue running SINDu Pi for implicit ODE, someone suggest it is due to sci-kit version , so I downgraded it to lower version but I am still having same error:

AttributeError Traceback (most recent call last)
Cell In[3], line 50
41 # Need to pass time base to the library so can build the x_dot library from x
42 sindy_library = ps.SINDyPILibrary(
43 library_functions=library_functions,
44 x_dot_library_functions=x_dot_library_functions,
(...)
47 include_bias=True,
48 )

57 model = ps.SINDy(
58 optimizer=sindy_opt,
59 feature_library=sindy_library,
60 differentiation_method=ps.FiniteDifference(drop_endpoints=True),
61 )
62 model.fit(x_train, t=t)

AttributeError: module 'pysindy' has no attribute 'SINDyPI'

Kindly suggest how to fix this

It is likely that you did not install the cvxpy extras. Run

pip install pysindy[cvxpy] next time to get scs and cvxpy packages. These are required for the SINDyPI optimizer. From your current position, you can just try to run pip install scs cvxpy.

Thanks it worked!
