Hi MD,
Some models in SAS Visual Data Mining and Machine Learning are packaged in a single downloadable DATA step code file. Other models are based on a SAS analytical store such as the model created by a Gradient Boosting or Forest node. Each analytic store is a binary representation of the state of an analytic procedure after training. This analytic store must also be accompanied by analytic store score code, also referred to as EP score code. These files represent your model and can be imported into your project.
Without knowing the exact steps that replicate your issue, I assume you’ve performed the following steps:
1) Select Download score code from the Project Pipeline menu in the Pipeline Comparison tab
2) Save the ZIP file.
3) Import the zip file to your project to define your model in SAS Model Manager.
4) Score a new table using "Manage Models" -> "Scoring" -> "New Test".
If my assumption is correct, you are seeing the error most likely because the ZIP file approach requires complete model contents consisting of model input and output metadata, and score code file. Additionally, if an analytical store is a part of the model, then the binary model file needs to be available in the ModelStore CAS library after a model is registered. Otherwise, you will get an error like what you are observing because this binary model file cannot be found.
Depending on the purpose of scoring, you can consider the following options: ·
-- If you only want to score a new table, then score within Model Studio. To score holdout data, complete the following steps:
- Select the waterfall icon in the upper right corner of the Pipeline Comparison
- Select Score holdout data.
- The Browse Data window appears. Select the data set that contains the holdout data that you want scored.
- Click OK.
- Model Studio will score the holdout data. To see the results of this process, use the Data menu below Pipeline Comparison to select Holdout.
-- If your objective is to manage and publish models, then score with SAS Model Manager.
- Click the waterfall icon in the upper right corner of the Pipeline Comparison tab in the interface of Model Studio and select Register models. This registers the model in SAS Model Manager. SAS Model Manager is used to store and organize models in a common repository.
- Score the new table using "Manage Models" -> "Scoring" -> "New Test".
Hope this helps.
