OpenCV kurulumu, "skbuild" i bulamadığı için başarısız oluyor

Aug 17 2020

OpenCV'yi kurmam gereken bir docker imajım var ve dün "skbuild" modülünü bulamadığı için başarısız olmaya başladı:

    ModuleNotFoundError: No module named 'skbuild'

Ve ana bilgisayarda da bu modülü bulamıyorum ve pip searchya hiçbir şey döndürmüyor ya da bir sunucu hatası veriyor:

sudo pip3 search skbuild

    raise Fault(**self._stack[0])

Bunun nedeni sunucularının bazı sorunları olması veya benim pip'imle ilgili olması mı?

Güncelleme

Bunu farklı python ve pip sürümlerinde, python 3.6 ve 3.7 sürümlerinde ve pip sürüm 19.12 ve 20.2.2 ve 9.0.1'de denedim (içerideki resim).

Eklediğim pip install scikit-buildopencv kurulumdan önce bir adım ama cmake ilişkin yaptığı bir hatayı alıyorum:

opencv-python PyPI'deki SSS paketini okursanız, bu özel sorun için açıkça bir cevap sağlar : koşmalısınızpip install --upgrade pip . pipDaha sonra ile sürümü kontrol edin pip -V.

Bunun nedeni pip, yeni manylinux2014paket biçimini anlamak için çok eski olmanız ve kaynaktan derlemeye çalışmasıdır. Bu da başarısız olacaktır pip, çünkü pyproject.tomlgibi derleme bağımlılıklarının nasıl kurulacağını anlamak için çok eski scikit-build.

Fark ettiğim bir diğer sorun da hem opencv-pythonve hem de yüklemeniz opencv-contrib-python. Bunu yapmamalısın. Ayrıca paketlerin PyPI sayfasında da açıklanmıştır. Büyük olasılıkla opencv-contrib-python-headlessDocker kullandığınız için sadece paket kullanmalısınız ve OpenCV'nin GUI işlevlerini kullanmadığınızı varsayıyorum.

skbuild Scikit-build içindir.

Pip kullanarak kurun:

Windows için: pip install scikit-build

Başarılı kurulumdan sonra:

pip install cmake
