これまでローカルでやってきたことをazure VM上で実行してみる。
（その３）では男女1名ずつだやったけれども、こんどは女性2名100枚ずつの画像でテスト。
と、その前に、忘れないようにメモメモっと。

#####結果

[yuni@machinelearningvm azureVM]$ find takei_emi/imgs | wc -l
624
沢尻エリカ：621枚
武井咲：624枚
###顔の検出
openCV動かす環境作るのにめちゃめちゃハマりました...
ハマりすぎて実行したこと全部かけない(汗）
#####結果
約600枚の画像について顔の切り出しには7-8分かかりました。
336
yuni@machinelearningvm azureVM]$ find takei_emi/face_only | wc -l
318
目で見て、ごみデータの削除。
273
[yuni@machinelearningvm ~]$ find azureVM/takei_emi/face_only | wc -l
284
めちゃ減った。。。600枚以上集めたはずなのに半分以下。
###準備（train/testデータの仕分けとラベルづけテキストの作成）
まずは前回と同じ100枚で学習
- trainデータ：沢尻エリカ(100枚), 武井咲(100枚)
- testデータ ：沢尻エリカ(30枚), 武井咲(30枚)
細かいけどやったこと（めも）
画像ファイル名の一覧をテキストファイルに書き出し
[yuni@machinelearningvm azureVM]$ls azureVM/sawajiri_erika/face_only > azureVM/sawa.txt
毎行末に0を追記
[yuni@machinelearningvm azureVM]$sed -i -e "s/\$/ 0/g" azureVM/sawa.txt
毎行頭にpathを追記
[yuni@machinelearningvm azureVM]$ sed "s@^@/home/yuni/azureVM/data/@g" azureVM/take.txt > azureVM/take1.txt
1行目から100行目をtrainデータとして書き出し
sed -n 1,100p azureVM/sawa.txt > azureVM/train0.txt
[yuni@machinelearningvm azureVM]$ cat train0.txt|wc -l
100
[yuni@machinelearningvm azureVM]$ cat train1.txt|wc -l
100
[yuni@machinelearningvm azureVM]$ cat test0.txt|wc -l
30
[yuni@machinelearningvm azureVM]$ cat test1.txt|wc -l
30
test0.txtの中身：沢尻エリカの顔切り出し後のデータpath 0（ラベル）

...
train.txtに、pathとラベル(0,1)のテキストをまとめる
[yuni@machinelearningvm azureVM]$ cat train0.txt train1.txt > train.txt
[yuni@machinelearningvm azureVM]$ cat train.txt |wc -l

#####結果１
沢尻エリカの画像10枚（0が帰って来れば正解まる）を使って検証しました。
9枚正解、1枚不正解でした。
（テストデータの正解率85%だから、まあこんなもの？検証というには枚数少なすぎ？）
