Running SAM backbone on frontend (cvat-ai#6019)
<!-- Raise an issue to propose your change (https://github.com/opencv/cvat/issues). It helps to avoid duplication of efforts from multiple independent contributors. Discuss your ideas with maintainers to be sure that changes will be approved and merged. Read the [Contribution guide](https://opencv.github.io/cvat/docs/contributing/). --> <!-- Provide a general summary of your changes in the Title above --> ### Motivation and context Resolved cvat-ai#5984 Resolved cvat-ai#6049 Resolved cvat-ai#6041 - Compatible only with ``sam_vit_h_4b8939.pth`` weights. Need to re-export ONNX mask decoder with some custom model changes (see below) to support other weights (or just download them using links below) - Need to redeploy the serverless function because its interface has been changed. Decoders for other weights: sam_vit_l_0b3195.pth: [Download](https://drive.google.com/file/d/1Nb5CJKQm_6s1n3xLSZYso6VNgljjfR-6/view?usp=sharing) sam_vit_b_01ec64.pth: [Download](https://drive.google.com/file/d/17cZAXBPaOABS170c9bcj9PdQsMziiBHw/view?usp=sharing) Changes done in ONNX part: ``` git diff scripts/export_onnx_model.py diff --git a/scripts/export_onnx_model.py b/scripts/export_onnx_model.py index 8441258..18d5be7 100644 --- a/scripts/export_onnx_model.py +++ b/scripts/export_onnx_model.py @@ -138,7 +138,7 @@ def run_export( _ = onnx_model(**dummy_inputs) - output_names = ["masks", "iou_predictions", "low_res_masks"] + output_names = ["masks", "iou_predictions", "low_res_masks", "xtl", "ytl", "xbr", "ybr"] with warnings.catch_warnings(): warnings.filterwarnings("ignore", category=torch.jit.TracerWarning) bsekachev@DESKTOP-OTBLK26:~/sam$ git diff segment_anything/utils/onnx.py diff --git a/segment_anything/utils/onnx.py b/segment_anything/utils/onnx.py index 3196bdf..85729c1 100644 --- a/segment_anything/utils/onnx.py +++ b/segment_anything/utils/onnx.py @@ -87,7 +87,15 @@ class SamOnnxModel(nn.Module): orig_im_size = orig_im_size.to(torch.int64) h, w = orig_im_size[0], orig_im_size[1] masks = F.interpolate(masks, size=(h, w), mode="bilinear", align_corners=False) - return masks + masks = torch.gt(masks, 0).to(torch.uint8) + nonzero = torch.nonzero(masks) + xindices = nonzero[:, 3:4] + yindices = nonzero[:, 2:3] + ytl = torch.min(yindices).to(torch.int64) + ybr = torch.max(yindices).to(torch.int64) + xtl = torch.min(xindices).to(torch.int64) + xbr = torch.max(xindices).to(torch.int64) + return masks[:, :, ytl:ybr + 1, xtl:xbr + 1], xtl, ytl, xbr, ybr def select_masks( self, masks: torch.Tensor, iou_preds: torch.Tensor, num_points: int @@ -132,7 +140,7 @@ class SamOnnxModel(nn.Module): if self.return_single_mask: masks, scores = self.select_masks(masks, scores, point_coords.shape[1]) - upscaled_masks = self.mask_postprocessing(masks, orig_im_size) + upscaled_masks, xtl, ytl, xbr, ybr = self.mask_postprocessing(masks, orig_im_size) if self.return_extra_metrics: stability_scores = calculate_stability_score( @@ -141,4 +149,4 @@ class SamOnnxModel(nn.Module): areas = (upscaled_masks > self.model.mask_threshold).sum(-1).sum(-1) return upscaled_masks, scores, stability_scores, areas, masks - return upscaled_masks, scores, masks + return upscaled_masks, scores, masks, xtl, ytl, xbr, ybr ``` ### How has this been tested? <!-- Please describe in detail how you tested your changes.
