Pythonの軽量な顔認識・顔属性分析フレームワーク・ライブラリ「deepface」をインストールする

スポンサーリンク

Pythonの軽量な顔認識・顔属性分析フレームワーク・ライブラリ「deepface」をインストールしてみます。

deepface（ディープフェイス）は、Python用の軽量な顔認識および顔属性分析（年齢、性別、感情、人種）フレームワークです。ライブラリのベースは、主にKerasとTensorFlow。またVGG-Face, Google FaceNet, OpenFace, Facebook DeepFace, DeepID, ArcFace,Dlibなどの最新モデルを搭載。

■Python

今回のPythonのバージョンは、「3.8.5」を使用しています。（Windows10）（pythonランチャーでの確認）

■deepfaceをインストールする

deepfaceをインストールを行いますが、今回はpipを経由してインストールを行うので、まずWindowsのコマンドプロンプトを起動します。

pip install deepface

起動後、上記のコマンドを入力し、Enterキーを押します。

なお、今回は、pythonランチャーを使用しており、Python Version 3.8.5にインストールを行うために、pipを使う場合にはコマンドでの切り替えを行います。

py -3.8 -m pip install deepface

切り替えるために、上記のコマンドを入力し、Enterキーを押します。

WARNING: You are using pip version 20.1.1; however, version 21.2.1 is available.
You should consider upgrading via the 'C:\Program Files\Python38\python.exe -m pip install --upgrade pip' command.

Enterキーを押すと、インストールが開始され、上記のように「Successfully installed」と表示されます。これが表示されれば、deepfaceが正常にインストールされたことになります。

なお、今回はdeepfaceのバージョン0.0.67をインストールしました。

ちなみに、今回インストールを行うと、「ERROR: tensorflow 2.5.0 has requirement numpy~=1.19.2, but you’ll have numpy 1.20.3 which is incompatible.」というエラーが発生。deepfaceのベースとなるtensorflowのバージョン2.5.0はnumpyモジュールの1.19.2を要求していますが、互換性のないnumpyモジュールのバージョン1.20.3を使用という内容なので、numpyをアンインストールし、バージョンを変更した方が良い。

バージョンを変更せずに、「ERROR: tensorflow 2.5.0 has requirement numpy~=1.19.2, but you’ll have numpy 1.20.3 which is incompatible.」というエラーが発生した状態で、顔の表情の検出してみましたが、検出することができました。
