通常、アプリケーションをインストールするときに、さまざまなファイルの欠落や、 .soファイルの欠落などの依存関係などの問題が発生することがよくあります。 Ubuntuには、依存関係を見つけるための強力なツール apt-fileが用意されています。 Docker Imageシステムは通常Ubuntuであるため、最も適切なシナリオはDockerで使用することです。
apt-fileのインストールコマンドは次のとおりです。
# Install
$ apt-get update
$ apt-get install apt-file
# Update apt-file
$ apt-file update
cv.pyファイルがない場合は、 cv.pyファイルを検索します。apt-fileは cv.pyを含むパッケージを一覧表示し、必要なパッケージが python-opencvであることを確認してから、 ythonをインストールします。 -opencv。
# コマンドフォーマット
$ apt-file seach [filename]
# Demo
$ apt-file search cv.py
