我正在尝试运行一项使用简单的变压器罗伯塔模型进行分类的服务。推理脚本/函数本身在测试时按预期工作。当我将它包含在快速 api 中时,它会关闭服务器。
uvicorn==0.11.8
fastapi==0.61.1
simpletransformers==0.51.6
cmd : uvicorn --host 0.0.0.0 --port 5000 src.main:app
@app.get("/article_classify")
def classification(text:str):
"""function to classify article using a deep learning model.
Returns:
[type]: [description]
"""
_,_,result = inference(text)
return result
错误 :

更新:尝试使用烧瓶并且服务正在运行,但是当在烧瓶顶部添加 uvicorn 时,它会陷入重启循环。
