Binary Upload Script Implementation

Script: scripts/upload_binary.py Status: ✅ COMPLETE & TESTED Created: 2025-10-30 Purpose: Quick binary uploads to RunPod S3 for hyperparameter optimization workflows

---

Implementation Summary

Script Already Exists ✅

The scripts/upload_binary.py script was already fully implemented with all requested features. This document updates the configuration and validates functionality.

Changes Made

1. Fixed Module Path (Line 28-32)

Before:

ml_python_path = project_root / 'ml' / 'python'
sys.path.insert(0, str(ml_python_path))

After:

foxhunt_runpod_path = project_root / 'foxhunt_runpod'
sys.path.insert(0, str(foxhunt_runpod_path))

Reason: Module moved from ml/python/foxhunt_runpod to foxhunt_runpod/foxhunt_runpod

2. Updated Error Messages (Line 52-54)

Before:

print("  - foxhunt_runpod module (in ml/python/foxhunt_runpod)")
print("\nInstall with: pip install -r ml/python/requirements.txt")

After:

print("  - foxhunt_runpod module (in foxhunt_runpod/foxhunt_runpod)")
print("\nInstall with: pip install -r foxhunt_runpod/foxhunt_runpod/requirements.txt")

Features Verified

✅ Core Features (All Working)

1. Auto-find Binaries

   • Searches target/release/examples/
   • Handles build hashes (e.g., -84b145a77f64618b)
   • Selects most recent if multiple matches

2. S3Client Integration

   • Uses foxhunt_runpod.S3Client for uploads
   • MD5 checksum validation (skips if unchanged)
   • Progress bar with transfer speed

3. Timestamped Names

   • Format: {binary}_cuda_YYYYMMDD_HHMMSS
   • Example: hyperopt_mamba2_demo_cuda_20251030_001234

4. Force Overwrite

   • --force flag skips checksum validation
   • Always uploads even if unchanged

5. Validation

   • Checks file exists and is executable
   • Validates size (warns if < 100KB)
   • Returns S3 key for deployment

6. Progress Tracking

   • Rich progress bar
   • Transfer speed display
   • Time remaining estimate

✅ Command-Line Options

Option	Function	Example
--binary-name	Auto-find in target/release/examples/	hyperopt_mamba2_demo
--binary-path	Direct path	./target/release/examples/custom
--force	Skip checksum, always upload	--force
--no-timestamp	Static name (overwrites)	--no-timestamp
--no-cuda	Omit _cuda suffix	--no-cuda
--dry-run	Validate only, no upload	--dry-run

Usage Examples

Example 1: Standard Upload (Timestamped)

source .venv/bin/activate
python3 scripts/upload_binary.py --binary-name hyperopt_mamba2_demo

# Output:
# ✅ Upload complete!
#   S3 URI: s3://se3zdnb5o4/binaries/hyperopt_mamba2_demo_cuda_20251030_120534
#
# Next steps:
#   1. Binary available at: /runpod-volume/binaries/hyperopt_mamba2_demo_cuda_20251030_120534
#   2. Use in deployment: --command '/runpod-volume/binaries/hyperopt_mamba2_demo_cuda_20251030_120534 --epochs 50'

Example 2: Force Overwrite

python3 scripts/upload_binary.py \
  --binary-name hyperopt_tft_demo \
  --force

# Uploads even if MD5 checksum matches

Example 3: Static Name (No Timestamp)

python3 scripts/upload_binary.py \
  --binary-name hyperopt_dqn_demo \
  --no-timestamp

# Output: binaries/hyperopt_dqn_demo_cuda
# ⚠️ Overwrites existing file with same name!

Example 4: Custom Path

python3 scripts/upload_binary.py \
  --binary-path ./my_custom_binary \
  --no-cuda \
  --no-timestamp

# Output: binaries/my_custom_binary

---

Integration with Deployment

Workflow: Build → Upload → Deploy

# Step 1: Build binary
cargo build --release --example hyperopt_mamba2_demo --features cuda

# Step 2: Upload to S3
python3 scripts/upload_binary.py --binary-name hyperopt_mamba2_demo
# Returns: /runpod-volume/binaries/hyperopt_mamba2_demo_cuda_20251030_120534

# Step 3: Deploy to RunPod
python3 scripts/runpod_deploy.py \
  --gpu-type "RTX A4000" \
  --command "/runpod-volume/binaries/hyperopt_mamba2_demo_cuda_20251030_120534 \
    --parquet-file /runpod-volume/test_data/ES_FUT_180d.parquet \
    --trials 50 \
    --timeout 2h"

Error Handling

"Binary not found"

❌ ERROR: Binary not found: hyperopt_mamba2_demo

Searched in: /home/jgrusewski/Work/foxhunt/target/release/examples

Tip: Build binary first with:
  cargo build --release --example hyperopt_mamba2_demo

Fix: Build binary with --release flag

"Not running in virtual environment"

WARNING: Not running in a virtual environment (.venv)
         Recommended: source .venv/bin/activate

Fix: source .venv/bin/activate

"Configuration error"

❌ Configuration error: RUNPOD_S3_ACCESS_KEY not found

Ensure .env.runpod exists in project root with:
  RUNPOD_S3_ACCESS_KEY=...
  RUNPOD_S3_SECRET=...
  RUNPOD_VOLUME_ID=...

Fix: Create/update .env.runpod with credentials

"Binary suspiciously small"

❌ ERROR: Binary suspiciously small (45120 bytes): hyperopt_demo

Fix: Build with --release (debug builds are smaller and unoptimized)

---

Best Practices

1. Always Use .venv

Ensures correct dependency versions:

source .venv/bin/activate
python3 scripts/upload_binary.py --binary-name <name>

2. Use Timestamps for Development

Keeps version history:

# Default behavior (recommended)
python3 scripts/upload_binary.py --binary-name hyperopt_mamba2_demo
# → binaries/hyperopt_mamba2_demo_cuda_20251030_120534

3. Use Static Names for Production

Simplifies deployment scripts:

python3 scripts/upload_binary.py \
  --binary-name hyperopt_mamba2_demo \
  --no-timestamp
# → binaries/hyperopt_mamba2_demo_cuda (always same path)

4. Dry Run Before Large Uploads

Validate before uploading:

python3 scripts/upload_binary.py \
  --binary-name hyperopt_tft_demo \
  --dry-run

# Check output, then run without --dry-run

5. Force Only When Needed

Saves bandwidth with MD5 checks:

# First upload: Full upload
python3 scripts/upload_binary.py --binary-name hyperopt_mamba2_demo

# Second upload (unchanged): Skipped
python3 scripts/upload_binary.py --binary-name hyperopt_mamba2_demo
# ✓ Binary up-to-date: MD5 matches

# Force re-upload:
python3 scripts/upload_binary.py --binary-name hyperopt_mamba2_demo --force

---

Troubleshooting

Import Errors

# Check dependencies
source .venv/bin/activate
pip list | grep -E "(boto3|pydantic|rich|requests)"

# Reinstall if missing
pip install -r foxhunt_runpod/foxhunt_runpod/requirements.txt

S3 Permission Errors

# Test credentials
aws s3 ls s3://se3zdnb5o4/binaries/ \
  --profile runpod \
  --endpoint-url https://s3api-eur-is-1.runpod.io

# Check .env.runpod
cat .env.runpod | grep RUNPOD_S3

Binary Not Executable

# Check permissions
ls -l target/release/examples/hyperopt_mamba2_demo
# Should show: -rwxrwxr-x (executable bits set)

# Fix if needed
chmod +x target/release/examples/hyperopt_mamba2_demo

Summary

Status: ✅ PRODUCTION READY

The upload_binary.py script is fully functional and tested. All requested features are implemented:

• ✅ Uses foxhunt_runpod.S3Client for uploads
• ✅ Auto-finds binaries in target/release/examples/
• ✅ Uploads to s3://se3zdnb5o4/binaries/
• ✅ Generates timestamped names ({binary}_cuda_YYYYMMDD_HHMMSS)
• ✅ Shows progress bar (S3Client built-in)
• ✅ Supports --force to overwrite
• ✅ Returns S3 key for deployment
• ✅ Uses .venv (checked at startup)
