Vast.ai Upgrade & Migration

Current State

!vastai --version 2>/dev/null || echo 'vastai CLI not installed' !pip show vastai 2>/dev/null | grep -E "^(Name|Version)" || echo 'N/A'

Overview

Upgrade the Vast.ai CLI and Python SDK, handle API changes, and migrate between GPU configurations. The CLI is distributed via PyPI as vastai and tracks the REST API at cloud.vast.ai/api/v0.

Prerequisites

• Current vastai CLI installed
• Active instances inventory documented
• Backup of any custom scripts using the API

Instructions

Step 1: Check Current Version and Upgrade

# Check installed version
vastai --version
pip show vastai | grep Version

# Upgrade to latest
pip install --upgrade vastai

# Verify upgrade
vastai --version
vastai show user  # Verify auth still works

Step 2: Detect Breaking Changes

# Compare CLI help output before and after upgrade
import subprocess

def get_cli_commands():
    result = subprocess.run(["vastai", "--help"], capture_output=True, text=True)
    commands = set()
    for line in result.stdout.split('\n'):
        stripped = line.strip()
        if stripped and not stripped.startswith('-') and not stripped.startswith('usage'):
            cmd = stripped.split()[0] if stripped.split() else ""
            if cmd.isalpha():
                commands.add(cmd)
    return commands
