can this software train models myself?

[liangwei191]

or it can only use pre-trained models?

[rozentill]

You can certainly train models yourself and extract feature maps from the model for patchmatch. We did not provide codes to train a model and use it, we just use a pre-trained model. If you want to do transfer on some special objects, it seems that you need to train a model yourself and modify the codes a little bit.
