While using the api i am encountering the following error:

Thanks a lot for developing this awesome library. It's incredibly well written with seamless workflow. I guess there was some discussion on robustifying the expr.gen_torch_exp() involving torch and cvxpy. Has there any incompatibility between different versions of torch and cvxpy.

Hello @pauldebdeep9, Thank you for your kind words. We have recently merged a PR that overhauls the way torch expressions are generated. Could you kindly pull that and see if the issue persists?

[pauldebdeep9]

Hi @AmitSolomonPrinceton, works fine. This is an awesome library. This area of optimization is evolving very quickly. The usage of torch is quite appropriate. Hope to witness the widespread adoption.
