やったこと

ちょっとずつパラメータを変えた3種類のモデル×各5foldでTTA(9 crops)して平均しただけ。

(初submitでは1種類のモデルだったけど結局スコア変わらなかった)

つかいかた

ライブラリ

  • Pillow-SIMD
  • better-exceptions
  • horovod
  • numba
  • numpy
  • opencv-python
  • scikit-learn
  • scipy
  • tensorflow-gpu
  • tqdm

怪しいDockerイメージを使ってたのでpipenvとかは用意してないけどたぶんこのくらい。

Pillow-SIMDはただのPillowでもよかったり、TensorFlowは1.13.0を使ったけどそこそこあたらしい1.x系ならたぶん動くくらいだったり。

学習

./run.sh model1.py
./run.sh model2.py
./run.sh model3.py

OpenMPIが無ければそのまま実行してもたぶん動くつもり。

推論

./averaging.py
