[grahamking]

1. Create my_engine.py

import asyncio

async def generate(request):
    yield {"id":"1","choices":[{"index":0,"delta":{"content":"The","role":"assistant"}}],"created":1841762283,"model":"Llama-3.2-1B-Instruct","system_fingerprint":"local","object":"chat.completion.chunk"}
    await asyncio.sleep(0.1)
    yield {"id":"1","choices":[{"index":0,"delta":{"content":" capital","role":"assistant"}}],"created":1841762283,"model":"Llama-3.2-1B-Instruct","system_fingerprint":"local","object":"chat.completion.chunk"}
    await asyncio.sleep(0.1)
    yield {"id":"1","choices":[{"index":0,"delta":{"content":" of","role":"assistant"}}],"created":1841762283,"model":"Llama-3.2-1B-Instruct","system_fingerprint":"local","object":"chat.completion.chunk"}
    await asyncio.sleep(0.1)
    yield {"id":"1","choices":[{"index":0,"delta":{"content":" France","role":"assistant"}}],"created":1841762283,"model":"Llama-3.2-1B-Instruct","system_fingerprint":"local","object":"chat.completion.chunk"}
    await asyncio.sleep(0.1)
    yield {"id":"1","choices":[{"index":0,"delta":{"content":" is","role":"assistant"}}],"created":1841762283,"model":"Llama-3.2-1B-Instruct","system_fingerprint":"local","object":"chat.completion.chunk"}
    await asyncio.sleep(0.1)
    yield {"id":"1","choices":[{"index":0,"delta":{"content":" Paris","role":"assistant"}}],"created":1841762283,"model":"Llama-3.2-1B-Instruct","system_fingerprint":"local","object":"chat.completion.chunk"}
    await asyncio.sleep(0.1)
    yield {"id":"1","choices":[{"index":0,"delta":{"content":".","role":"assistant"}}],"created":1841762283,"model":"Llama-3.2-1B-Instruct","system_fingerprint":"local","object":"chat.completion.chunk"}
    await asyncio.sleep(0.1)
    yield {"id":"1","choices":[{"index":0,"delta":{"content":"","role":"assistant"},"finish_reason":"stop"}],"created":1841762283,"model":"Llama-3.2-1B-Instruct","system_fingerprint":"local","object":"chat.completion.chunk"}

2. Build

cargo build --release --feature python

3. Run

dynemo-run out=pystr:my_engine.py --name test

And here's a distributed system, with your engine:

• Node 1: dynemo-run in=http out=dyn://test
• Node 2: dynemo-run in=dyn://test out=pystr:my_engine.py

Curious about making the request type schema more flexible or configurable in the future - but this looks great! Very exciting addition!
