PrototxtとCaffemodelって何だ？

Last updated at Posted at 2019-03-10

Memo#

Darknet/Yoloのモデルや重みデータを、prototxt、caffemodelに変換したいので調べてます。

やりたい事はつまり、Tsingjinyunの説明を引用しますと、

「Darknet configuration file .cfg to the .prototxt definition in Caffe, a tool to convert the weight file .weights to .caffemodel in Caffe and a detection demo to test the converted networks.」

Convert Darknet model to Caffe's#

検索すると、関係するリンクが集められたサイトがあった。その中のリンクを含め片っ端から調べてみる。

Tsingjinyun/Caffe-YOLO2###

This is a set of tools to convert models from Darknet to Caffe, and in particular to convert the YOLO networks for object detection. For more details, see the paper:

手当たり次第、cfgとweightsを使って実行してみた。まずcfgからprototxtへの変換。

READMEに従い、できあがったprototxtとcaffemodelを使って、Caffeで動かして確認する。

# python yolo_detect.py \
　darknet_deploy.prototxt darknet.caffemodel \
　images/dog.jpg

エラーを吐いて実行できず。
このGitにある元々のファイルを使うと、tiny-yoloだけOKだった。

# python yolo_detect.py \
　prototxt_caffemodel/tiny_yolo_deploy.prototxt　prototxt_caffemodel/tiny_yolo.caffemodel \

深追いは止めて、一先ずここまでにしておく:thermometer_face:

Pushyami/YOLOv3-Caffe###

Pytorchで、スクラッチからYOLOv3を実装する方法ということらしく、「オブジェクト検出の学習に取り組むための最善の方法は、最初からアルゴリズムを自分で実装すること」と書かれていました。

Part1#####

YOLOのしくみ、層の説明があり、参考になるかな。

Part2#####

YOLOのcfg（つまりCaffeのprototxt）の簡単な説明がある。YOLOで使用されるレイヤは、Convolutional、Shortcut、Upsample、Route、YOLO（検知層）の5種類だそうな。

Part3#####

Pytorchでの実装に入ってくるので、ビギナーにはつらいな～:frowning2:

Part4######
Part5#####

Jasonlovescoding/YOLOv3-Caffe###

CaffeでYolov3を動かしているみたい。
prototxtとcaffemodelをGoogleDriveからダウンロードできたので、Netronで見てみると、100ぐらいの隠れ層があって、とっても深～い！Netronの表示結果は　ここ　をクリック。

Python3のCaffeが必要みたい、良くわからないので断念:sob:

ChenYingpeng/Caffe-YOLOv3###

こちらはBaidouにprototxt/caffemodel、cfg/weightsがUpされているが、Baidouのアプリをインストールしないといけないようで、怖いから止めとこ:relaxed:

Marvis/Pytorch-Caffe-Darknet-convert###

Pytorch、Caffe、DarknetのConvert、これもPytorchが要る。

# python darknet2caffe.py \
  ../darknet_Cfg-Weights/tiny-yolo-voc.cfg \
  ../darknet_Cfg-Weights/tiny-yolo-voc.weights \
  tiny-yolo-voc.prototxt tiny-yolo-voc.caffemodel

  File "/home/hoge/temp/darknet2caffe/Marvis_Pytorch-Caffe-Darknet/cfg.py", line 1, in <module>
    import torch
ImportError: No module named torch

仕方ない、Pytorchをインストールしてみるか:frowning2:

Ysh329/Darknet2Caffe###

ysh329/darknet-to-caffe-model-convertorが元のようで、これもPytorchがいるみたい:thinking:

This is a caffe implementation of the YOLO

まだ試していない・・・

まだ試していない・・・

Xilinx/ML-Suite###

まだ試していない・・・

Abars/Darknet2Caffe###

これもPytorchが必要みたい:rolling_eyes:
