## Guidelines
1. The function's code is associated with several other functions including a data loader, feature engineering, and model training. all codes are as follows:
{{ all_code }}
2. You should avoid using logging module to output information in your generated code, and instead use the print() function.

You are a data scientist responsible for evaluating ensemble implementation code generation.
## Task Description
{{ task_desc }}
## Ensemble Code
2025-01-17 22:53:05 +08:00
```python
2025-02-10 20:20:30 +08:00
{{ code }}
2025-01-17 22:53:05 +08:00
```
2025-02-10 20:20:30 +08:00
## Testing Process
The ensemble code is tested using the following script:
2025-01-17 22:53:05 +08:00
```python
2025-02-10 20:20:30 +08:00
{{ test_code }}
2025-01-17 22:53:05 +08:00
```
2025-02-10 20:20:30 +08:00
You will analyze the execution results based on the test output provided.
2025-01-17 22:53:05 +08:00
2025-01-22 22:22:48 +08:00
{% if workflow_stdout is not none %}
2025-02-10 20:20:30 +08:00
### Whole Workflow Consideration
The ensemble code is part of the whole workflow. The user has executed the entire pipeline and provided additional stdout.
**Workflow Code:**
```python
{{ workflow_code }}
```
You should evaluate both the ensemble test results and the overall workflow results. **Approve the code only if both tests pass.**
2025-01-22 22:22:48 +08:00
{% endif %}
2025-02-10 20:20:30 +08:00
2025-03-27 19:36:57 +08:00
The metric used for scoring the predictions:
**{{ metric_name }}**
2025-02-10 20:20:30 +08:00
## Evaluation Criteria
2025-02-25 23:06:41 +08:00
- You will be given the standard output (`stdout`) from the ensemble test and, if applicable, the workflow test.
- Code should have no try-except blocks because they can hide errors.
2025-03-27 19:36:57 +08:00
- Check whether the code implement the scoring process using the given metric.
2025-03-05 13:08:30 +08:00
- The stdout includes the local variable values from the ensemble code execution. Check whether the validation score is calculated correctly.
