S2_reconstruct.py Fails to Write Mesh on Windows: RPly: Unable to create file (Directory Not Found)

[j422917558]

🐛 Bug Report

I am encountering a file writing error when attempting to run the Stage 2 reconstruction script (S2_reconstruct.py) on a Windows environment. The script appears to be failing to create the necessary output directory structure before attempting to save the PLY file.

The error seems to stem from a path resolution/directory creation issue specific to Windows execution.

Steps to Reproduce

1. Run the data download: ```bash
   bash download_data.sh

2. Execute the Stage 2 reconstruction command for the ABC test set:

   python S2_reconstruct.py --delta=0.0 --dataset=ABC_test

Expected Behavior

The script should automatically create the full output directory structure (results/ABC_test/ABC_test/) and successfully save the reconstructed .ply mesh file.

Actual Behavior (Full Error Message)

The script throws the following error/warning and fails to write the file:
