我试图调用mlrun中的函数，但出现上述错误。任何人都可以帮助我在that.im上附加代码...

from cloudpickle import load
import numpy as np
from typing import List
import mlrun

class ClassifierModel(mlrun.serving.V2ModelServer):
    def load(self):
        """load and initialize the model and/or other elements"""
        model_file, extra_data = self.get_model('.pkl')
        self.model = load(open(model_file, 'rb'))

    def predict(self, body: dict) -> List:
        """Generate model predictions from sample."""
        feats = np.asarray(body['inputs'])
        result: np.ndarray = self.model.predict(feats)
        return result.tolist()

以下代码将您在上一步中定义的ClassifierModel类转换为服务函数。服务函数使用的类名在spec.default_class中设置。

serving_fn = mlrun.code_to_function('serving', kind='serving',image='mlrun/mlrun')
serving_fn.spec.default_class = 'ClassifierModel'

model_file = project.get_artifact_uri('my_model') 
serving_fn.add_model('my_model',model_path=model_file)

在本地测试函数

my_data = '''{"inputs":[[5.1, 3.5, 1.4, 0.2],[7.7, 3.8, 6.7, 2.2]]}'''

server = serving_fn.to_mock_server()
server.test("/v2/models/my_model/infer", body=my_data)

# Building and Deploying the Serving Function¶

function_address = serving_fn.deploy()

print (f'The address for the function is {function_address} \n')

!curl $function_address

# Now we will try to invoke our serving function

serving_fn.invoke('/v2/models/my_model/infer', my_data)
