[BUG]Cannot use TrappingSR3 #432

Closed SimonYYS closed 7 months ago

SimonYYS commented 7 months ago

TrappingSR3 is not working, even in the example you provided '8_trapping_sindy_paper_examples': https://pysindy.readthedocs.io/en/latest/examples/8_trapping_sindy_paper_examples/example.html

Other optimizers I tried works fine..

Error message:

AttributeError: module 'pysindy' has no attribute 'TrappingSR3'

Python 3.11.5

Please share pysindy version. Also, based on relevant info, what are your cvxpy, osqp, and scs versions?

Thanks for the reply.

pysindy ver 1.7.5 osqp ver 0.6.3 cvxpy ver 1.4.1 scs ver 3.2.4.post1

Thanks. Let's get a bit more diagnostic error. Can you try to directly import the trapping_sr3.py module?

import pysindy.optimizers.trapping_sr3

import pysindy.optimizers.trapping_sr3

Now it works magically. That's cool.

Glad to hear. For context pysindy skips importing TrappingSR3 from pysindy/optimizers/trapping_sr3.py if the latter runs into an error importing CVXPY. So it looks like something about your CVXPY install was updated or fixed between your first error and the last attempt.
