[Kwant] Haldane Model issue since 1.4 version

Dear Kwant community I try to execute from conda-kwant the code for the Haldane model from course "Topology in Condensed Matter: Tying Quantum Knots" on my computer. When executing the code appears the next issue: haldane_model.py:162: KwantDeprecationWarning: The 'args' parameter has been deprecated since version 1.4 -- Instead, provide named parameters as a dictionary via 'params'. mat = sys.hamiltonian_submatrix(args=[par]) I read kwant manual but the change from "args" to "params" modify the definition of others functions and appear other issues. Maybe it is a silly question but I am stuck. Thank you and I look forward to your answer. César
