Bonjour à tous, Dans le cadre d'un projet scolaire j'ai besoin d'effectuer une reconnaissance d'images. Pour cela j'ai décidé d'utiliser la bibliothèque OpenCV sous Python. (J'utilise anaconda si ça peut servir.)

runfile('C:/Users/leots/Documents/1-Scolaire/Prepa SUP/info/sanstitre0.py', wdir='C:/Users/leots/Documents/1-Scolaire/Prepa SUP/info') système -> Windows jeu d'instructions -> 32bit distribution -> 10.0.18362 version python -> 3.7.6

Pour l'installation j'ai ouvert anaconda prompt et entré la ligne de code relative à l'installation d'open cv :

conda install -c conda-forge opencv

Et là c'est le drame, après des heures à tourner, la console me renvoie un flot d'erreurs que je ne comprends pas. Donc voilà si quelqu'un parvient à comprendre ce qui ne marche pas ou a une autre idée pour installer cette bibliothèque ce serait vraiment sympa... ; )

Le message d'erreur renvoyé par la console est vraiment très long, je peux l'envoyer en intégralité en PJ si besoin, voilà le début :

(base) C:\Users\leots>conda install -c conda-forge opencv Collecting package metadata (current_repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible solve. Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source. Collecting package metadata (repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible solve. Solving environment: / Found conflicts! Looking for incompatible packages. This can take several minutes. Press CTRL-C to abort.

Alors tu peux utiliser un fichier wheel se trouvant ICI

Après il suffira de faire un pip install file.whl

où file sera l'endroit où tu as stocké ton fichier wheel.

Salut, Un dernier petit message avant de fermer ce chat, Après un certain temps j'ai réussi (enfin) mon installation en entrant tout simplement py -3.7 -m pip install opencv-python

3.7 étant ma version de python En espérant qu'une des trois commandes proposées ici puissent aider quelqu'un Encore merci pour ton aide

salut j'ai le même problème que toi et après ce que j'ai lu ce doit être un problème d'environnement.... et pares exécution de ton code déjà très difficile a lire,(

 pip install opencv-python

) voici ce que j'ai sur la console
