MobileSAM CPU mask polylines convert_masks current patch

You are converting histopathology cell masks to polylines using MobileSAM in the Terminal-Bench sam-cell-seg container.

Debugging signal. The task requires MobileSAM rather than the original SAM, CPU-only execution, and an output CSV that preserves the input columns while converting all rectangular masks into non-overlapping polylines.

MobileSAM CPU support mobile_sam checkpoint libGL.so.1 convert_masks.py rectangle masks polylines

Typical failures are missing mobile_sam imports, OpenCV libGL.so.1 import errors, checkpoint path confusion, or a convert_masks.py script that still leaves rectangle masks in the output.

Current checkout patch

Install the runtime pieces needed by MobileSAM/OpenCV, load the MobileSAM checkpoint on CPU, refine each rectangle prompt, convert contours to coords_x/coords_y polylines, and preserve the metadata schema.

Why this note is specific to this task

The command above is tied to the Terminal-Bench task sam-cell-seg and to the failure pattern described here. General project documentation is still useful background, but it usually does not keep the benchmark path, old dependency version, and final validation command in one place.
