Hi @nathanieltagg, thanks for your interest in SparseInst! I'm glad to hear about the usage of SparseInst and I'm concerned about some details as follows:
NUM_MASKS=100
, which keeps the pre-trained weights of the IAM?@wondervictor Thanks for the response! I turned down masks in the hopes that it would reduce parameter space, but I'll try the other way too.
So far we've tried the R-50 and the R-50-giam models, without much change. We're trying to segment the face of loading pallets. We've got about 8k labelled images at 1080p, most with a single instance but a few with mutliple instances. The annotation quality is quite good; we've trained an RCNN detectron model with great success, but we're after more speed and better segmentation with obscruring obstacles.
Any suggestions would be welcome! Thanks!
Hi, we're interested in evaluating this model, and we're trying to run it over our custom dataset with our custom object, so we have only one class, and usually just have a handful of instances in an image. We've tried loading the R-50 model and setting cfg.MODEL.SPARSE_INST.DECODER.NUM_MASKS = 10 cfg.MODEL.SPARSE_INST.DECODER.NUM_CLASSES = 1 This generates errors when loading the pre-trained model. It does actually train, but objects have very bad boundaries. The loss function does not seem to be converging after the first few iterations, and bounces up and down further than we'd expect.
Would it be possible to have a quick example showing how to add an object class, or any pointers on things to try? Thanks!
