Saving Selected Hyperparameter Search Results for Analysis
Summary
This short Chinese-language forum exchange addresses how to preserve promising results from a quantitative strategy’s hyperparameter search. The example need is to save parameter sets whose score exceeds a chosen threshold. The poster reports that attempts to write files directly from the scoring function, using built-in file opening or pandas serialization, did not work in that environment.
The response recommends using a custom run module for more flexible analysis. In that workflow, collect the results for the different parameter settings after the sample strategy finishes, convert them to a DataFrame, and export the table as a CSV. This provides a practical separation between running the search and inspecting or saving its outputs. The post does not explain the platform restriction behind the failed calls, show a complete implementation, or specify how to handle large searches, concurrent runs, or other file formats. Its advice is therefore a high-level workflow rather than a fully documented solution.
Key ideas
- Direct file writing from the scoring function failed for the poster in the described environment.
- A custom run module can provide a more flexible place to collect hyperparameter results.
- Results for different parameter settings can be converted into a DataFrame for further analysis.
- The response suggests exporting that table as a CSV file.
- The post gives a workflow recommendation but no complete implementation or explanation of the platform limitation.
