            This space hosts the ShaderEval Suite. more to follow soon.

            # Task1: Return Completion
            ## Explanation
            Modelled after the [CodeXGLUE code_completion_line](https://huggingface.co/datasets/code_x_glue_cc_code_completion_line) task. 
            Using the "return_completion" subset of the [Shadertoys-fine dataset](https://huggingface.co/datasets/Vipitis/Shadertoys-fine).
            All preprocessing and post proessing is done by the custom evaluator for this suite. It should be as easy as just giving it a model checkpoint that can do the "text-generation" task.
            Evaluated is currently with just [exact_match](https://huggingface.co/metrics/exact_match).

            ## Notice
            should you find any model that throws an error, please let me know in the issues tab. Several parts of this suite are still missing.

            ## Instructions
            ### Run the code yourself:.
            ```python
            import evaluate
            suite = evaluate.EvaluationSuite.load("Vipitis/ShaderEval")
            model_cp = "gpt2"
            suite.run(model_cp, snippet=300)
            ```
            
            ### try the demo below
            - Select a **model checkpoint** from the "dropdown"
            - Select how many **samples** to run (there us up to 300 from the test set)
            - Click **Run** to run the suite
            - The results will be displayed in the **Output** box
            
            ## Results 
            ![](file/bar.png)
            Additionally, you can report results to your models and it should show up on this [leaderboard](https://huggingface.co/spaces/autoevaluate/leaderboards?dataset=Vipitis%2FShadertoys-fine)

            ## Todo (feel free to contribute in a [Pull Request](https://huggingface.co/spaces/Vipitis/ShaderEval/discussions?status=open&type=pull_request))
            - [~] leaderboard (via autoevaluate and self reporting)
            - [?] supporting batches to speed up inference 
            - [ ] CER metric (via a custom metric perhaps?)
            - [x] removing the pad_token warning
            - [ ] adding OpenVINO pipelines for inference, pending on OpenVINO release
            - [ ] task1b for "better" featuring a improved testset as well as better metrics. Will allow more generation parameters
            - [ ] semantic match by comparing the rendered frames (depending on WGPU implementation?)
            - [ ] CLIP match to evaluate rendered images fitting to title/description
