+ # Metric Card for apps_metric
20
+
21
+ ## Metric Description
22
+ This metric is used to evaluate code generation on the [APPS benchmark](https://huggingface.co/datasets/codeparrot/apps).
23
+
24
+ ## How to Use
25
+ You can load the metric and use it with the following commands:
26
+
27
+ ```python
28
+ from evaluate import load
29
+ apps_metric = load('codeparrot/apps_metric')
30
+ # to evaluate generations made for all levels for example
31
+ results = apps_metric.compute(predictions=generations, level="all")
32
+ ```
33
+
34
+ ### Inputs
35
+ **generations** list(list(str)): List of code generations, each sub-list corresponds to the generations for a problem in APPS dataset, **the order of the samples in the dataset must be kept (with respect to the difficulty level)**.
36
+
37
+ ### Output Values
38
+
39
+ **average accuracy**: when a single solution is generated, average accuracy computes the average of test cases that are passed.
40
+
41
+ **strict accuracy**: when a single solution is generated, strict accuracy computes the average number of problems that pass all their test cases.
42
+
43
+ **pass@k**: when multiple solutions are generated per problem, pass@k is the metric originally used for the [HumanEval](https://huggingface.co/datasets/openai_humaneval) benchmark. For more details please refer to the [metric space](https://huggingface.co/spaces/evaluate-metric/code_eval) and [Codex paper](https://arxiv.org/pdf/2107.03374v2.pdf).
