dat1-cli 0.1.4

No project description provided

dat1-cli

A command line interface for the dat1 platform.

Installation

pip install dat1-cli

Usage

Initialize with your API key:

dat1 login

To initialize a new model project, run in the root directory of your project:

dat1 init

This will create a dat1.yaml file in the root directory of your project. This file contains the configuration for your model:

model_name: <your model name>
exclude:
  - '**/.git/**'
  - '**/.idea/**'
  - '*.md'
  - '*.jpg'
  - .dat1.yaml

Exclude uses glob patterns to exclude files from being uploaded to the platform.

To upload your model to the platform:

dat1 deploy

A good starting point for your model is using the example model.

Otherwise, the platform expects a handler.py file in the root directory of your project that contains a FastAPI app with two endpoints: GET / for healthchecks and POST /infer for inference. An example handler is shown below:

from fastapi import Request, FastAPI
from vllm import LLM, SamplingParams
import os

llm = LLM(model=os.path.expanduser('./'), load_format="safetensors", enforce_eager=True)

app = FastAPI()

@app.get("/")
async def root():
    return "OK"

@app.post("/infer")
async def infer(request: Request):
    request = await request.json()
    prompts = request["prompt"]
    sampling_params = SamplingParams(temperature=0.8, top_p=0.95)
    outputs = llm.generate(prompts, sampling_params)
    return { "response" : outputs[0].outputs[0].text }
