You need to setup your environment first. Please install latest nvidia drivers, cuda 9 and cudnn 7. After that run setup_env.sh script

How to run predict

unzip test data into data_test folder and

./predict_test.sh

Submission files will be in predictions folder (submission_0.csv, submission_1.csv). Individual model predictions will be also in predictions folder.

How to run training

Before training please remove models from:

• albu/weights
• selim/nn_models
• victor/nn_models
• victor/lgbm_models

after it run:

./train_all.sh
./tune_all.sh
./predict_oof_trees.sh

We use two stage training because we want to tune models on the stage1 data released 11.04. Every script goes into every folder and runs scripts to train models.
