tavor 1.0.0

Python SDK for Tavor cloud sandboxes

Tavor Python SDK

Official Python SDK for Tavor, the cloud sandbox platform that provides secure, isolated execution environments.

Installation

pip install tavor

For async support:

pip install tavor[async]

Quick Start

from tavor import Tavor

# Initialize the client
tavor = Tavor(api_key="sk-tavor-...")

# Create and use a sandbox
with tavor.box() as box:
    result = box.run("echo 'Hello from Tavor!'")
    print(result.stdout)  # "Hello from Tavor!"

Features

• Simple API: Intuitive interface for creating and managing boxes
• Automatic cleanup: Boxes are automatically cleaned up when done
• Streaming output: Real-time command output streaming
• Async support: Full async/await support for concurrent operations
• Type hints: Complete type annotations for better IDE support
• Error handling: Comprehensive error handling with specific exception types

Usage Examples

Basic Command Execution

from tavor import Tavor

tavor = Tavor(api_key="sk-tavor-...")

with tavor.box() as box:
    # Run simple commands
    result = box.run("pwd")
    print(f"Current directory: {result.stdout}")

    # Install packages
    box.run("pip install numpy pandas")

    # Run Python code
    result = box.run("python -c 'import numpy as np; print(np.array([1,2,3]))'")
    print(result.stdout)

Error Handling

from tavor import Tavor, CommandTimeoutError, TavorError

try:
    with tavor.box() as box:
        # This will timeout
        result = box.run("sleep 120", timeout=5)
except CommandTimeoutError as e:
    print(f"Command timed out: {e}")
except TavorError as e:
    print(f"Error: {e}")

Streaming Output

with tavor.box() as box:
    # Stream output as it's generated
    result = box.run(
        "for i in {1..5}; do echo \"Line $i\"; sleep 1; done",
        on_stdout=lambda line: print(f"[LIVE] {line}", end=""),
        on_stderr=lambda line: print(f"[ERROR] {line}", end="")
    )

Custom Box Configuration

from tavor import Tavor, BoxConfig, BoxTemplate

config = BoxConfig(
    template=BoxTemplate.PRO,  # More CPU and RAM
    timeout=7200,  # 2 hours
    metadata={"project": "data-analysis"}
)

with tavor.box(config=config) as box:
    # Run resource-intensive tasks
    result = box.run("python train_model.py")

Async Operations

import asyncio
from tavor import AsyncTavor

async def run_parallel_tasks():
    async with AsyncTavor(api_key="sk-tavor-...") as tavor:
        async with tavor.box() as box:
            # Run multiple commands in parallel
            results = await asyncio.gather(
                box.run("task1.py"),
                box.run("task2.py"),
                box.run("task3.py")
            )

            for result in results:
                print(result.stdout)

asyncio.run(run_parallel_tasks())

Manual Box Management

# Create a box without automatic cleanup
box = tavor.create_box()

try:
    # Wait for box to be ready
    box.wait_until_ready()

    # Run commands
    result = box.run("echo 'Hello'")
    print(result.stdout)

    # Check box status
    print(f"Box status: {box.status}")
finally:
    # Don't forget to clean up!
    box.stop()

API Reference

Client Classes

• Tavor: Main client for synchronous operations
• AsyncTavor: Client for async operations (requires pip install tavor[async])

Configuration

• BoxConfig: Configuration for box creation
  • template: Use predefined templates (BoxTemplate.BASIC, PRO) - defaults to BASIC
  • template_id: Use custom template ID
  • timeout: Maximum lifetime in seconds (default: 3600, or TAVOR_BOX_TIMEOUT env var)
  • metadata: Custom metadata dictionary

Models

• Box: Represents a box instance
• CommandResult: Result of command execution
  • stdout: Command output
  • stderr: Error output
  • exit_code: Process exit code
  • status: Command status (QUEUED, RUNNING, DONE, FAILED, ERROR)

Exceptions

• TavorError: Base exception for all SDK errors
• APIError: Base for API-related errors
• AuthenticationError: Invalid API key
• BoxNotFoundError: Box doesn't exist
• CommandTimeoutError: Command execution timeout
• ValidationError: Invalid request parameters

Environment Variables

The SDK supports the following environment variables:

• TAVOR_API_KEY: Your API key (alternative to passing it in code)
• TAVOR_BASE_URL: API base URL (default: https://api.tavor.dev)
• TAVOR_CPU: CPU to allocate to the sandbox (default: 1)
• TAVOR_MIB_RAM: MiB RAM to allocate to the sandbox (default: 1024)
• TAVOR_BOX_TIMEOUT: Default box timeout in seconds (default: 3600)

Example:

export TAVOR_API_KEY="sk-tavor-..."
export TAVOR_BASE_URL="https://api.tavor.dev"
export TAVOR_BOX_TIMEOUT="7200"
export TAVOR_CPU="1"
export TAVOR_MIB_RAM="1024"

# Now you can initialize without parameters
python -c "from tavor import Tavor; client = Tavor()"

Requirements

• Python 3.9+
• requests library
• aiohttp (optional, for async support)
