最近、性能良いとうわさのYolov3が出てきたので、ちょっと試したいと思って試してみた。

ちょっと。。。以下のサイトにたくさん事例があり、ほとんど同じようなことが書いてあるので、簡単なんだろうと思っていた。

###環境作成するよ。。。
darknetでYOLOv3を動かしてみた。の記事のとおり、話を進める。
Ubuntuのようなので、以下を参考にWindows10（1060-3GB）にUbuntuを入れる。
Ubuntu がマイクロソフトストアにやってきた
これはなんとなく再起動して動いた。
そして、「深層学習フレームワークdarknetをインストールする。」

git clone https://github.com/pjreddie/darknet.git
cd darknet

たぶん、ここはハマらずdarknetという一連のディレクトリができると思う。。。
※ウワンはここでもハマった様子①のとおり、ハマりましたが。。。

そして、
「Makefileを修正し、GPUとOpenCVをOnにし、makeする。」
これは、viでMakefileを以下のように編集して、その後makeするという意味です。
※当たり前だけど、。。。少し、ハマりました

vi Makefile

viが無い。。。ということで、ここは単に編集すればいいので、jupyter notebookからMakefileを呼び出して以下の部分を編集しました。

変更前(Makefile)
GPU=0
CUDNN=0
OPENCV=0
OPENMP=0
DEBUG=0

変更後(Makefile)
GPU=1
CUDNN=0
OPENCV=1
OPENMP=0
DEBUG=0

そして、問題はmake。。。
※ここはハマった様子②のようにすごくハマりました

make

無いです。。。

$ sudo apt install make

で入りましたが、gccが必要です。

$ sudo apt-get install gcc

そして、「YOLOv3の学習済みファイルをダウンロードする」

wget https://pjreddie.com/media/files/yolov3.weights

※ここでも実はハマってました。yolo.weightsというファイルもあって、こっちをダウンロードして以下実施するとweightsの読み込みエラーが出てthe endです

ということで、いよいよ「YOLOv3をテストする」

./darknet detect cfg/yolov3.cfg yolov3.weights data/dog.jpg

※以下のyolov3のネットワーク構造と実行結果の通り、動きました

dog: 99%
truck: 92%
bicycle: 99%

そして、以下yolov2の結果です。
yolov2.weightsをダウンロードして、

$ wget https://pjreddie.com/media/files/yolov2.weights

実行します。

$ ./darknet detect cfg/yolov2.cfg yolov2.weights data/dog.jpg

両者で精度はかなり異なりますね。。。

dog: 81%
truck: 74%
bicycle: 83%

めでたしめでたし。。。ですが、。。。
これは、C版です。。。ということで、python版動くかな？？

MuAuan@DESKTOP-S5LF5OV:/mnt/c/Users/user/darknet/python$ python3 darknet.py cfg/yolov3.cfg yolov3.weights data/dog.jpg
Traceback (most recent call last):
  File "darknet.py", line 48, in <module>
    lib = CDLL("libdarknet.so", RTLD_GLOBAL)
  File "/usr/lib/python3.5/ctypes/__init__.py", line 347, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: libdarknet.so: cannot open shared object file: No such file or directory

"libdarknet.so"のファイルが見つかりません。。。
ここでも実はかなりハマりましたが、端折ります。。。

ということで、。。。以下の記事に乗り換えました。
【Darknet】リアルタイムオブジェクト認識 YOLOをTensorflowで試す

これ。。。簡単に動くといいなぁ～
今日はここまでにいたしとうござります^^;

###まとめ
・今回は、噂のYolov3を動かしてみた
・環境構築にすごくハマった
・結果はYolov3はYolov2に比較するとネットワーク構造もディープになって、検出精度も格段に上がっていた
・Python版は動かなかった

以下種々ハマったところなど、参考です。
####ハマった様子①darknetの環境作るまで
前半、YOLOv2(Keras / TensorFlow)でディープラーニングによる画像の物体検出を行うで環境構築を始めたので、その状況が入っています。。。
