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.
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.
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.
Accepted answer
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.

The important detail is to validate the exact benchmark artifact rather than stopping at a general upstream answer. The search terms for this failure are: MobileSAM CPU support mobile_sam checkpoint libGL.so.1 convert_masks.py rectangle masks polylines.
