调研方向

The warning is raised inside scipy at scipy.optimize._differentiable_functions:728 during the climada.test.test_util_calibrate tests, so start by running that test module and finding which calibration call passes a zero gradient difference. Decide whether the fix belongs in climada's calibration code (for example, supplying a Hessian or changing the optimizer call) or whether the warning should be suppressed in the tests, and say which in the discussion. Done means the test run no longer emits the warning, or the issue records why it is expected.

描述

warnings

UserWarning

delta_grad == 0.0. Check if the approximated function is linear. If the function is linear better results can be obtained by defining the Hessian as zero instead of using quasi-Newton approximations.
