Overview

BOHB-template

실행 방법

python main.py

2021-10-10 기준

  • tf keras 버전 (tunecallback 방식) 완료
  • tf gradienttape 버전 (train_iteration 방식) 완료
  • pytorch 버전은 구현 준비중

방법 소개

1. 라이브러리 설치

ray 및 tune 설치

pip install ray[tune]

bohb의 경우

pip install hpbandster ConfigSpace

2. 스케쥴러의 max_t 설정

  • keras나 torch의 epoch은 max_t 값을 기준으로 terminate된다. HB 계열일 경우 eta (reduction_factor)도 잘 고려해서 설정하자.

3. 샘플 수 설정

  • tune.run의 샘플 수는 config에서 정한 조합 중 seed에 맞춰 설정한 수에 맞춰 선별된다.

선별된 샘플은 다음과 같이 pending 되고, running 된다.

+-----------------------+----------+-------+--------------+-----------+-----------+--------------+
| Trial name            | status   | loc   | activation   |   neuron1 |   neuron2 | optimizers   |
|-----------------------+----------+-------+--------------+-----------+-----------+--------------|
| objective_dd8c7_00000 | PENDING  |       | tanh         |        43 |        50 | adam         |
| objective_dd8c7_00001 | PENDING  |       | relu         |        63 |        45 | adam         |
| objective_dd8c7_00002 | PENDING  |       | tanh         |        63 |        52 | rmsprop      |
+-----------------------+----------+-------+--------------+-----------+-----------+--------------+

4. stop 조건 설정

  • tune.run의 stop 항목의 t의 값에 따라 멈출 수 있다.

예를 들어

stop={
"mean_accuracy": 0.99, # 정확도가 0.99 이상일 경우 Terminate
"training_iteration": 1
},

이 경우 max_t가 아무리 길어도, trial이 모두 다 running되었을 때(1번), 1번으로 간주되어 종료된다.

Number of trials: 3/3 (3 TERMINATED)
+-----------------------+------------+-------+--------------+-----------+-----------+--------------+----------+--------+------------------+
| Trial name            | status     | loc   | activation   |   neuron1 |   neuron2 | optimizers   |      acc |   iter |   total time (s) |
|-----------------------+------------+-------+--------------+-----------+-----------+--------------+----------+--------+------------------|
| objective_dd8c7_00000 | TERMINATED |       | tanh         |        43 |        50 | adam         | 0.938278 |      1 |          5.3518  |
| objective_dd8c7_00001 | TERMINATED |       | relu         |        63 |        45 | adam         | 0.942333 |      1 |          5.15036 |
| objective_dd8c7_00002 | TERMINATED |       | tanh         |        63 |        52 | rmsprop      | 0.94     |      1 |          4.28608 |
+-----------------------+------------+-------+--------------+-----------+-----------+--------------+----------+--------+------------------+

5. BOHB의 max_concurrent 및 cpu 값을 잘 활용

  • 병렬적으로 처리하게 되어 최적화 속도가 개선될 수 있다.

6. 시각화

  • 실행 시 지정한 경로에 기록이 쌓이는데, tensorboard 명령어로 확인이 가능하다.
tensorboard --logdir bohb_results/
