🔧 Issues Resolved

1. Configuration Mismatch ✅ FIXED

   • Removed conflicting --load_best_model_at_end with --do_eval False

2. Missing Dependencies ✅ FIXED

   • Installed accelerate>=0.26.0
   • All transformers dependencies satisfied

3. Model Download Timeout ✅ WORKAROUND PROVIDED

   • Created scripts/download_models.py for pre-download
   • Extended timeout settings available

4. Gradient Checkpointing Error ✅ FIXED

   • Custom GLENP1Model doesn't support gradient checkpointing
   • Removed from all training scripts
