Using custom sandbox with Code Interpreter SDK

If you want to customize the Code Interprerter sandbox (e.g.: add a preinstalled package) you can do that by using a custom sandbox template.

Step-by-step guide

Create custom sandbox by following this guide
Use prebuilt E2B Code Interpreter image by replacing the FROM command in your e2b.Dockerfile with following
```
FROM e2bdev/code-interpreter:latest
```
Copy start-up.sh to the same directory where's your e2b.toml
Run the following in the same directory where's your e2b.toml
```
e2b template build -c "/root/.jupyter/start-up.sh"
```

Use your custom sandbox with Code Interpreter SDK

Python

from e2b_code_interpreter import Sandbox
sandbox = Sandbox.create(template="your-custom-sandbox-name")
execution = sandbox.run_code("print('hello')")
sandbox.kill()

# Or you can use `with` which handles closing the sandbox for you
with Sandbox.create(template="your-custom-sandbox-name") as sandbox:
    execution = sandbox.run_code("print('hello')")

JavaScript/TypeScript

import {Sandbox} from '@e2b/code-interpreter'

const sandbox = await Sandbox.create({template: 'your-custom-sandbox-name'}) const execution = await sandbox.runCode('print("hello")') await sandbox.kill()
