Hello. I am wondering if there is any workarounds in the library to support box constraints during the Levenberg Marquardt optimization. Any guidance would help tremendously. Thanks in advance!

SciPy has the option to use the Levenberg-Marquardt algorithm in the least_squares function via the `method="lm"` argument. This method doesn’t handle bounds, but in Pastas parse them by default. My s…

I have instructed a 3d reconstruction and it appears that it got stuck in LM strategy. My images had low number of features so I get why, but I must admit it's quite annoying that it spends hours just…

Thanks you for sharing this library.
In some case using forward automatic differentiation can be useful, for example when solving non-linear least square problems, where having the jacobian matrix o…

# Summary of your issue
The classes and functions related to Rotation Estimation and Bundle adjustment seems to be missing.
These are part of the core Stitching module but can normally be used dir…

# Feature
Implementation of Levenberg Marquardt optimizer.
# Motivation
In MATLAB, the `feedforwardnet` supports many optimizers, and some are not implemented in PyTorch, such as `trainlm` ([Levenb…
