Banana Dev

6.3.0 · abandoned · verified Tue Apr 07

Python client for Banana's serverless GPU inference platform. Platform permanently shut down March 31, 2024. Package is abandoned. All API calls fail — the backend no longer exists. Do not use.

Common errors

```
requests.exceptions.ConnectionError: HTTPConnectionPool(host='api.banana.dev', port=443): Max retries exceeded with url: /...
```
cause The Banana.dev API server is no longer operational, so the client cannot establish a connection.

fix The Banana.dev platform has shut down. There is no fix to resume service with this library. Users should migrate to an alternative serverless GPU inference platform.
```
requests.exceptions.ConnectionError: ('Connection aborted.', ConnectionRefusedError(111, 'Connection refused'))
```
cause The attempt to connect to the Banana.dev API endpoint was actively refused because the server is not running or listening on the specified port.

fix The Banana.dev platform has shut down. There is no fix to resume service with this library. Users should migrate to an alternative serverless GPU inference platform.
```
ModuleNotFoundError: No module named 'banana_dev'
```
cause The `banana-dev` Python package has not been installed in the current environment.

fix Install the package using pip: `pip install banana-dev`. Note: While this resolves the import error, API calls will still fail due to the platform's shutdown.
```
banana.InvalidAPIKeyError
```
cause Even if a theoretically valid API key is provided, the backend infrastructure required to validate it and process requests no longer exists, leading to an authentication failure from the client's perspective as it cannot communicate with the service.

fix The Banana.dev platform has shut down. While checking the API key's validity might be a first step if the platform were operational, the core issue is the backend's absence. Users should migrate to an alternative platform.

Warnings

breaking Banana.dev platform permanently shut down March 31, 2024. All API calls raise ConnectionError. The backend does not exist.
Fix: Migrate to Modal (closest DX) and ensure it is installed (e.g., via `pip install modal`), RunPod (lowest cost), Replicate (easiest API), or fal.ai.
breaking Package is unmaintained. No releases since shutdown. Do not use banana-dev in any new project.
Fix: Remove banana-dev from requirements.txt entirely.
gotcha Tutorials and LLM-generated code referencing banana.dev or the potassium server framework are entirely non-functional. The potassium library is open-source but unmaintained and has no hosting target.
Fix: Discard any banana.dev or potassium-based code. Rewrite against Modal or RunPod.
gotcha ModuleNotFoundError: No module named 'modal'. The 'modal' library is a required dependency that needs to be installed.
Fix: Install the 'modal' package using pip: `pip install modal`.

Install

pip install banana-dev Python (abandoned — do not use)

Imports

banana

wrong:

import banana
banana.run(api_key, model_key, inputs)

correct:

# No valid usage — platform shut down March 31, 2024

banana.run() will raise a connection error. The API endpoint no longer exists.

Quickstart

Platform is dead. This quickstart shows the recommended Modal migration pattern.

# banana.dev shut down March 31, 2024.
# All API calls will fail with a connection error.
# Migrate to: Modal, RunPod, Replicate, or fal.ai

# Modal equivalent:
import modal
app = modal.App()

@app.function(gpu="A10G")
def run_model(inputs):
    # your model code
    pass
