EfficientSAM と OpenVINO によるオブジェクトのセグメント化¶
この Jupyter ノートブックは、ローカルへのインストール後にのみ起動できます。
セグメント・エニシング・モデル (SAM) は、数多くのビジョン・アプリケーション向けの強力なツールとして登場しました。ゼロショット転送と高い汎用性を実現する優れたパフォーマンスを実現する重要なコンポーネントは、広範囲にわたる高品質の SA-1B データセットでトレーニングされた超大規模トランスフォーマー・モデルです。SAM モデルは有益ではあるものの、計算コストが膨大であるため、その応用範囲は実世界のより広範なアプリケーションに限定されています。この制限に対処するため、複雑さを大幅に削減しながら適切なパフォーマンスを発揮する軽量 SAM モデルである EfficientSAM が提案されました。EfficientSAM のアイデアは、効果的な視覚表現学習のために SAM 画像エンコーダーから特徴を再構築することを学習するマスクされた画像の事前トレーニング (SAMI) を活用することに基づいています。

モデルの詳細については、論文、モデルのウェブページ、元のリポジトリーを参照してください
このチュートリアルでは、OpenVINO を使用して EfficientSAM を変換して実行する方法について説明します。また、NNCF を使用してモデルを量子化する方法も示します
目次¶
必要条件¶
%pip install -q "openvino>=2023.3.0" "nncf>=2.7" opencv-python matplotlib "gradio>=4.13" torch torchvision --extra-index-url https://download.pytorch.org/whl/cpu
DEPRECATION: pytorch-lightning 1.6.5 has a non-standard dependency specifier torch>=1.8.*. pip 24.1 will enforce this behaviour change. A possible replacement is to upgrade to a newer version of pytorch-lightning or contact the author to suggest that they release a version with a conforming dependency specifiers. Discussion can be found at https://github.com/pypa/pip/issues/12063
Note: you may need to restart the kernel to use updated packages.

PyTorch モデルのロード¶
リポジトリーにはいくつかのモデルが用意されています。
efficient-sam-vitt - 画像エンコーダーとして Vision Transformer Tiny (VIT-T) を搭載した EfficientSAM。EfficientSAM ファミリーの最小かつ最速のモデル。
efficient-sam-vits - 画像エンコーダーとして Vision Transformer Small (VIT-S) を搭載した EfficientSAM。Efficiency-sam-vitt よりも重いですが、より正確なモデルです。
EfficientSAM は、モデルとの対話のための統一されたインターフェースを提供します。つまり、ノートブックで提供されるモデルの変換と実行のすべての手順は、すべてのモデルで同じになります。以下では、例としてそのうちの 1 つを選択できます。
from efficient_sam.build_efficient_sam import build_efficient_sam_vitt, build_efficient_sam_vits
import zipfile
MODELS_LIST = {"efficient-sam-vitt": build_efficient_sam_vitt, "efficient-sam-vits": build_efficient_sam_vits}
# Since EfficientSAM-S checkpoint file is >100MB, we store the zip file.

PyTorch モデル推論を実行¶
PyTorchモデルを選択してロードすると、その結果を確認できます
入力データを準備¶
まず、モデルの入力データを準備する必要があります。モデルには 3 つの入力があります。
- 画像テンソル - 正規化された入力画像を持つテンソル。
- 入力ポイント - ユーザーが指定したポイントを持つテンソル。これは、画像上の特定のポイント (画面上でのユーザーのクリックによって提供されるものなど) である場合もあれば、左上の角度ポイントと右下の角度ポイントの形式の境界ボックス座標である場合もあります。
- 入力ラベル - 指定された各ポイントのポイントタイプの定義を含むテンソル。
- 通常のポイント
- 境界ボックスの左上のポイント
- 境界ボックスの右下のポイント
from PIL import Image
image_path = "figs/examples/dogs.jpg"
image = Image.open(image_path)

入力および出力処理のヘルパーを定義¶
以下のコードは、モデル入力と後処理推論結果を準備するためのヘルパーを定義します。入力形式は、上記のモデルで受け入れられます。モデルは、画像上の各ピクセルのマスクロジットと、各領域の交差と結合のスコア、指定されたポイントにどれだけ近いかを予測します。結果の視覚化のためのヘルパー関数もいくつか用意しました。

モデルを OpenVINO IR 形式に変換¶
OpenVINO は、OpenVINO モデル変換 API を使用して中間表現 (IR) 形式に変換することにより、PyTorch モデルをサポートします。openvino.convert_model 関数は、PyTorch モデルのインスタンスとサンプル入力 (正しいモデル操作のトレースと形状の推論に役立ちます) を受け入れ、OpenVINO フレームワークでモデルを表す openvino.Model オブジェクトを返します。この openvino.Model は、ov.Core.compile_model を使用してデバイスに読み込む準備ができており、openvino.save_model を使用してディスクに保存することもできます。

量子化¶
NNCF は、モデルグラフに量子化レイヤーを追加し、トレーニング・データセットのサブセットを使用してこれらの追加の量子化レイヤーのパラメーターを初期化することで、トレーニング後の量子化を可能にします。このフレームワークは、元のトレーニング・コードへの変更が最小限になるように設計されています。
最適化プロセスには次の手順が含まれます。
量子化用のキャリブレーション・データセットを作成します。
nncf.quantizeを実行して、量子化されたエンコーダーおよびデコーダーモデルを取得します。openvino.save_model関数を使用してINT8モデルをシリアル化します。
注: 量子化は時間とメモリーを消費する操作です。以下の量子化コードの実行には時間がかかる場合があります。
EfficientSAM 量子化を実行するかどうかを以下から選択してください。

キャリブレーション・データセットの準備¶
最初のステップは、量子化のキャリブレーション・データセットを準備することです。量子化には coco128 データセットを使用します。通常、このデータセットはオブジェクト検出タスクを解決するために使用され、そのアノテーションは画像のボックス座標を提供します。この場合、ボックス座標はオブジェクト・セグメント化の入力ポイントとして機能し、以下のコードはデータセットをダウンロードし、EfficientSAM モデルの入力を準備する DataLoader を作成します。

モデル量子化の実行¶
nncf.quantize 関数は、モデルの量子化のインターフェイスを提供します。OpenVINO モデルのインスタンスと量子化データセットが必要です。オプションで、量子化プロセスの追加パラメーター (量子化のサンプル数、プリセット、無視される範囲など) を提供できます。EfficientSAM には、活性化の非対称量子化を必要とする非 ReLU 活性化関数が含まれています。さらに良い結果を得るため、mixed 量子化プリセットを使用します。モデル・エンコーダー部分はビジョン・トランスフォーマー・アーキテクチャーに基づいており、このアーキテクチャー・タイプに特別な最適化を有効にするには、model_type で transformer を指定する必要があります。

FP16 モデルと INT8 モデルの推論時間を比較¶
FP16 モデルと INT8 モデルの推論パフォーマンスを測定するには、bencmark_app を使用します。
