Force Agg matplotlib backend + miner-facing polish#17
Merged
Conversation
- backtest.py: charts render in worker threads; the default GUI backend on macOS can only run on the main thread, so every chart failed there. Force the non-interactive Agg backend before importing pyplot. - pyproject: fill the placeholder description. - README: back-link to the synth-subnet miner tutorial (the repo is now linked from the miner getting-started docs and synthdata.co/miners).

backtest.py: force the non-interactiveAggmatplotlib backend before importing pyplot. Charts are rendered inside worker threads, and GUI backends (the macOS default) can only run on the main thread — on macOS every chart failed withCannot create a GUI FigureManager outside the main threadwhile the scoring itself succeeded. Verified: a fresh-clonerun_backtest.py --miner-name my_model --competition crypto-24h --asset BTCnow writes all six charts on macOS;uv run pytest tests/backtester/still passes (53 tests).pyproject.toml: fill the placeholder package description.Context
