buildathena-sdk 0.1.33

Athena Python SDK for block development

athena-sdk

Python SDK for building blocks and workflows on the Athena ML orchestration platform.

Installation

pip install buildathena-sdk

Quick Start

Define a Block

from athena import block, BlockContext

@block(name="TrainModel", outputs=["checkpoint"])
async def train_model(ctx: BlockContext, epochs: int = 100):
    for epoch in range(epochs):
        loss = train_epoch()
        await ctx.emit_metric("loss", loss, epoch=epoch)

    ref = await ctx.artifacts.register("model.pt", schema_type="checkpoint")
    return {"checkpoint": ref}

Use Credentials

Declare required secrets in the @block decorator and access via ctx.secrets:

from athena import block, BlockContext

@block(name="MyBlock", secrets=["OPENAI_API_KEY"])
async def my_block(ctx: BlockContext, config):
    key = ctx.secrets["OPENAI_API_KEY"]

Features

• Block Decorator: @block for defining workflow nodes
• Handler Decorator: @handler for custom URI scheme storage backends (s3://, gs://)
• Inspector Backend: @inspector_backend protocol for interactive UI plugins
• BlockContext: Emit metrics, progress, logs, and register artifacts
• Config System: YAML with $include, $extends, ${ref} substitution
• Discovery: AST-based scanner for workspace block detection
• Credentials: Secure secret management with @block(secrets=...) and ctx.secrets
