I'm looking for a trained colorization model (wlnet file) that is available to download and immediate use in 11.2. Checking the 21 currently existing NetModels:

all = Flatten[ResourceSearch /@ {"model", "net", "trained"}];
netmodels = DeleteCases[all, x_ /; FreeQ[x, "NeuralNet", \[Infinity]]];

shows such a model it's not available yet as a NetModel[].


Found an unusable example (no data/training code and uses deprecated code) here, might be a starting point.

There are two colorization nets available right now: NetModel["ColorNet Image Colorization Trained on Places Data (Raw Model)"] and NetModel["ColorNet Image Colorization Trained on ImageNet Competition Data (Raw Model)"]. For usage, see here and here.

  • $\begingroup$ But could you give examples about how to train the Model in the website? $\endgroup$

    $\begingroup$ @partida: showing how to train would make it way harder for us to add models. Many models have been trained for days/weeks, often using datasets that are not generally available, and if they are available, they are often massive requiring careful out-of-core processing and pre-processing. It would be very hard for us to verify that our training instructions result in a similar model to the pretrained one. If you want to reproduce the training, you will need to read the reference paper. $\endgroup$
