研究方向

從 sasctl/pzmm/mlflow_model.py 中的 MLFlowModel.read_mlflow_model_file() 開始,特別檢查 stack trace 中所示的 inputs_dict 和 outputs_dict 解析過程。使用所參照的 MLflow 模型目錄重現此範例,並檢查產生的模型中繼資料;當該方法在沒有 JSONDecodeError 的情況下回傳三個預期的字典時,即表示完成。

描述

bug

Describe the issue
Trying to read mlflow model using pzmm.MLFlowModel.read_mlflow_model_file result in JSONDecodeError. I'm just using a simple example from here:
https://medium.com/@rehabreda/registering-mlflow-models-to-sas-model-manager-using-sasctl-a-comprehensive-guide-a47dbf183338

To Reproduce
The rest of the training code can be found on the above link. The code that perform the read mlflow model file is shown below:

## define randomforest model 
model = RandomForestClassifier(n_estimators=300).fit(x_train, y_train)

##Model signature defines schema of model input and output
signature = infer_signature(x_train, model.predict(x_train))

## log model score to mlflow
score = model.score(x_test, y_test)
print("Score: %s" % score)
mlflow.log_metric("score", score)

### log model 
mlflow.sklearn.log_model(model, "model", signature=signature)
print("Model saved in run %s" % mlflow.active_run().info.run_uuid)

mlPath = Path(f'./mlruns/1/{mlflow.active_run().info.run_uuid}/artifacts/model')

## get info aboud model variables ,input and output
varDict, inputsDict, outputsDict = pzmm.MLFlowModel.read_mlflow_model_file(mlPath)

Expected behavior
Getting the dictionary successfully from pzmm.MLFlowModel.read_mlflow_model_file().
