概要

This article is related to ADDA (light scattering simulator based on the discrete dipole approximation).

ADDA | TensorFlow > TFRecordsへのIntField-Y格納と試し読み v0.2 > 5次元のinput node: [mr], [mi]追加
にて作成したPythonスクリプトを実際にTFRecords化したいディレクトリに対して実行するためのbashスクリプトを作成した。

ディレクトリ内構成

(追記 2017/07/29)
以下のスクリプトで計算したADDAの結果を含んでいる。

run_adda_170701.py
import subprocess as sb

# on Python 3.5.2

# codingrule: PEP8

RUN_PARAM = "-store_int_field -grid 26"
# RUN_PARAM = "-store_int_field"  # for test

# real part of refractive index
mrs = 1.33, 1.4, 1.45, 1.5
# imaginary part of refractive index
mis = 0.0001, 0.001, 0.01, 0.03, 0.05, 0.1

for amr in mrs:
    for ami in mis:
        cmd = "./adda -m %f %f %s" % (amr, ami, RUN_PARAM)
        print(cmd)
        sb.run(cmd.split(), stdout=sb.DEVNULL)

$ ls ../run376_sphere_g26_m1.5/
CrossSec-Y  IntField-Y  log  mueller

ADDAによる計算直後は上記のファイルがある。

  • IntField-Y: 対象とするデータが入ったファイル
  • log: refractive indexの情報を含むログファイル

対象ディレクトリ

$ ls ../run3
run353_sphere_g26_m1.33/ run358_sphere_g26_m1.33/ run363_sphere_g26_m1.4/  run368_sphere_g26_m1.45/ run373_sphere_g26_m1.5/

run356_sphere_g26_m1.33/ run361_sphere_g26_m1.4/  run366_sphere_g26_m1.45/ run371_sphere_g26_m1.5/  run376_sphere_g26_m1.5/

処理の概要

  1. 各ディレクトリに対して対象ファイルのシンボリックリンクを貼る
  2. logからrefractive indexの情報を取得
  3. IntField-YをTFRecordsファイルに変換
  4. 結果ファイルを対象ディレクトリにコピーする
