Pinferencia?

没听说过Pinferencia，这不是你的错。主要我的宣传经费，实在是不够多。

你是不是训练了一堆模型，然而别人谁用都不行。不是环境搞不定，就是bug命太硬。

你想:

要是我能有个API，谁能不陷入我的爱。不用安装不用等待，发个请求结果自己到来。

可是世上API千百万，却没有哪个我能玩得转。用来用去，看来还是我心太软，有些产品真的不能惯。

我多想这个世界变得简单，我的模型1分钟就能上线。然而现实这么残酷，一天两天过去，我的眼泪哗哗止不住。

到底谁能给予我这个恩赐啊，看来只有Pinferencia。

还嫌不够?

创建应用程序

app.py
import joblib
import uvicorn

from pinferencia import Server


# train your model
model = "..."

# or load your model
model = joblib.load("/path/to/model.joblib") # (1)

service = Server()
service.register(
    model_name="mymodel",
    model=model,
    entrypoint="predict", # (2)
)

  1. For more details, please visit https://scikit-learn.org/stable/modules/model_persistence.html

  2. entrypoint is the function name of the model to perform predictions.

    Here the data will be sent to the predict function: model.predict(data).

app.py
import torch
import uvicorn

from pinferencia import Server


# train your models
model = "..."

# or load your models (1)
# from state_dict
model = TheModelClass(*args, **kwargs)
model.load_state_dict(torch.load(PATH))

# entire model
model = torch.load(PATH)

# torchscript
model = torch.jit.load('model_scripted.pt')

model.eval()

service = Server()
service.register(
    model_name="mymodel",
    model=model,
)
