autosmith

Make tools quickly

Install

You must have docker installed and running.

pip install autosmith

Usage

The package will inspect a python function, its imports, argument types, and start a container that serves it on an endpoint.

from autosmith.smith import smith
import requests

def hello():
    """Return hello"""
    return 'hello'

with smith(hello) as env:
    r = requests.get(env.url + '/hello')
    print(r.text)
    # 'hello'

By default, the container will be removed when returned ToolEnv (env below) is garbage collected. You can keep the container via env.save(). You can then load via env.load().

def double(x: int):
    """Double an integer"""
    return x * 2

env = smith(double)
url = env.url + '/double?x=2'
r = requests.get(url)
print(r.text)
# 4

env.name = 'myenv'
env.save()
del env

r = requests.get(url)
print(r.text)
# 4

env = ToolEnv.load('myenv')

# now the container will be removed since we didn't save
del env

The ToolEnv object is meant to collect functions and slowly build up an environment. Note that the functions you define need not be executable in your python environment.

def nparange(n: int):
    """Return a numpy array"""
    import numpy as np
    # can only output standard python types
    return np.arange(n).astype(int).tolist()

def double(x: int):
    """Double an integer"""
    return x * 2

env = smith(nparange)
env = smith(double, env=env)

r = requests.get(env.url + '/nparange?n=5')
print(r.text)
# [0, 1, 2, 3, 4]
env.close() # another way to close the container
