Latest Trackio Space Deployment Approach

Overview

Based on the Hugging Face Hub repository code, I've updated the Trackio Space deployment to use the latest Hugging Face Hub Python API instead of CLI commands.

Key Improvements

1. Latest HF Hub API Integration

Before: Using CLI commands

cmd = ["hf", "repo", "create", f"{username}/{space_name}", "--type", "space"]

After: Using Python API

from huggingface_hub import create_repo

create_repo(
    repo_id=f"{username}/{space_name}",
    token=token,
    repo_type="space",
    exist_ok=True,
    private=False,
    space_sdk="gradio",
    space_hardware="cpu-basic"
)

2. Robust Fallback Mechanism

The deployment script now includes both API and CLI approaches:

def create_space(self) -> bool:
    """Create a new Hugging Face Space using the latest API"""
    try:
        if not HF_HUB_AVAILABLE:
            return self._create_space_cli()
        
        # Use latest API
        create_repo(...)
        
    except Exception as api_error:
        # Fallback to CLI
        return self._create_space_cli()

3. Enhanced Dependencies

Updated requirements/requirements_core.txt:

# Hugging Face Hub for model and space management
huggingface_hub>=0.19.0

API Parameters

Required Parameters

repo_id: Repository identifier (username/space-name)
token: Hugging Face token with write permissions

Optional Parameters

repo_type: Set to "space" for Spaces
exist_ok: Allow existing repositories (default: True)
private: Make repository private (default: False)
space_sdk: SDK type (default: "gradio")
space_hardware: Hardware specification (default: "cpu-basic")

Deployment Process

Step 1: API Creation

# Create space using latest API
create_repo(
    repo_id=f"{username}/{space_name}",
    token=token,
    repo_type="space",
    exist_ok=True,
    private=False,
    space_sdk="gradio",
    space_hardware="cpu-basic"
)

Step 2: File Preparation

# Prepare files in temporary directory
temp_dir = tempfile.mkdtemp()
# Copy template files
shutil.copy2(source_path, dest_path)
# Update README with actual space URL
readme_content.replace("{SPACE_URL}", self.space_url)

Step 3: Git Upload

# Initialize git in temp directory
os.chdir(temp_dir)
subprocess.run(["git", "init"], check=True)
subprocess.run(["git", "remote", "add", "origin", space_url], check=True)
subprocess.run(["git", "add", "."], check=True)
subprocess.run(["git", "commit", "-m", "Initial Trackio Space setup"], check=True)
subprocess.run(["git", "push", "origin", "main"], check=True)

Expected output: ``` 🚀 Testing Latest Trackio Space Deployment

🔍 Testing huggingface_hub import... ✅ huggingface_hub imported successfully

🔍 Testing deployment script import... ✅ TrackioSpaceDeployer class imported successfully ✅ HF API initialized

🔍 Testing API methods... ✅ Method exists: create_space ✅ Method exists: _create_space_cli ✅ Method exists: prepare_space_files ✅ Method exists: upload_files_to_space ✅ Method exists: test_space ✅ Method exists: deploy

🔍 Testing create_repo API... ✅ Required parameter: repo_id ✅ Required parameter: token ✅ Optional parameter: repo_type ✅ Optional parameter: space_sdk ✅ Optional parameter: space_hardware ✅ create_repo API signature looks correct

🔍 Testing space creation logic... ✅ Space URL formatted correctly ✅ Repo ID formatted correctly

🔍 Testing template files... ✅ app.py exists ✅ requirements.txt exists ✅ README.md exists

🔍 Testing temporary directory handling... ✅ Created temp directory: /tmp/tmp_xxxxx ✅ File copying works ✅ Cleanup successful

📊 Test Results: 7/7 tests passed ✅ All deployment tests passed! The latest deployment should work correctly.

## Usage Instructions

### **1. Install Latest Dependencies**
```bash
pip install huggingface_hub>=0.19.0

2. Test the Deployment

python tests/test_latest_deployment.py

3. Deploy Trackio Space

python scripts/trackio_tonic/deploy_trackio_space.py

4. Verify Deployment

Check the Space URL
Test the interface
Verify API endpoints

Troubleshooting

Common Issues

1. Import Errors

❌ Failed to import huggingface_hub

Solution: Install latest version

pip install huggingface_hub>=0.19.0

2. API Errors

API creation failed: 401 Client Error

Solution: Check token permissions and validity

3. Git Push Errors

❌ Error uploading files: git push failed

Solution: Verify git configuration and token access

Fallback Behavior

The deployment script automatically falls back to CLI if:

huggingface_hub is not available
API creation fails
Network issues occur

Reference Implementation

Based on the Hugging Face Hub repository, this implementation:

Uses the latest API patterns
Follows HF Hub best practices
Maintains backward compatibility
Provides robust error handling

The Trackio Space deployment should now work reliably with the latest Hugging Face Hub infrastructure! 🚀
