Bonjour !
Edit: article en préversion en cours de validation !
(edition: j'avais oublié Xformers: corrigé)
Vour rêvez d'avoir un summerbody impeccable avant l'été ?
Ce n'est pas trop tard grâce à l'IA......
Framepack est un projet pour faire des vidéos très réalistes à partir d'une photo...... et qui marche sur un pc gamer de supermarché, à condition de ne pas être trop pressé.....
Voici une installation avec Xformers, Sage et Flash attn sur windows .....
Oui, j'ai trouvé une solution !
Voici le tuto pour installer Framepack dans Windows 11 avec un GPU de type Geforce RTX3050 ti laptop....
Il faut avoir un environnement python (3.10) et Git installé au préalable sur son PC ++++
On y va:
Créer un dossier plutot vers la racine de votre disque dur ou sur un disque dur très très rapide de préférence....
Ex: D:/FramePackTwo
allez ensuite dans ce dossier avec le navigateur de fichier....
Dans l'adresse de navigation: tapez cmd
Cela ouvre une fenêtre de commande ouvert directement au niveau de ce dossier.
(C'est une astuce hyperpratique et ça évite de se déplacer à coup de commandes CD ) travers les répertoires....
Il faudra avant installer le programme "GIT" pour windows si vous ne l'avez pas encore fait:
ici: https://git-scm.com/downloads/win
dans la fenêtre de commande:
On va cloner le dépot Framepack de Github:
Tapez juste dans la fenêtre de commande:
git clone https://github.com/lllyasviel/FramePack
et voilà....
fermez cette fenêtre de commande.
on va créer un fichier Batch pour installer les bibliothêques compatibles pour windows 11 et la carte graphique Geforce RTX 3050 ti laptop
créer un fichier texte,
ex: "NouveauTexte.txt"
Collez le texte au dessus dedans et enregistrez le....
Changez son nom en "install_env.bat"
Mettez ce fichier dans le répertoire "Framepack" créé par GIT:
ICI:
lancez ensuite une nouvelle fenêtre de commande en tapant CMD dans la barre d'adresse (là ou "Framepack" est écrit)
DAns la fenêtre de commande:
On lance: install_env.bat
tout s'installe avec les bonnes bibliothêques.....
Vous aurez un truc du genre:

Ouf.....
DANS CETTE MEME FENETRE DE COMMANDE TAPEZ:
python demo_gradio.py
pour lancer ce script.....
Si vous avez tout fermé ou pas envie de tout réinstaller:
Dans une nouvelle fenêtre de commande ouverte dans le répertoire Framepack, il faudra réactiver l'environnement virtuel AVANT de lancer le script....
1: on réactive l'environnement virtuel créé en tapant dans cette nouvelle fenêtre de commande:
call .venv\Scripts\activate.bat
Puis on pourra lancer le script:
python demo_gradio.py
ou si ça ne marche pas:
py demo_gradio.py
Normalement ça marche avec le minimum et si vous êtes un utilisateur lambda, ça passe crême !
En mode GEEK !
Pour nettoyer les dernières scories qui vous pique les yeux:
Il faut installer pleins d'autres trucs et je vous déconseille si vous ne maitrisez pas.
Compiler Xformers:
créer ce fichier "compile_xformers.bat" dans le répertoire où il y a et lancer le fichier "install_env.bat"

là, ça marche....
Le reste, je sêche un peu (mais je vais corriger bientôt)

Mais par contre, j'ai des soucis avec ce script.....
Stay tuned !
Je vais corriger ça bientôt.
relancer ensuite "install_env.bat"
Des bogues très énervants que j'ai rencontré:
Lors de la compilation:
Noms de fichiers trop long....
ex:
Cloning into 'D:/Framepacktwo/FramePack/xformers/third_party/flash-attention'... error: unable to create file library/src/tensor_operation_instance/gpu/gemm_multiply_multiply/device_gemm_multiply_multiply_xdl_f8_f8_bf16/device_gemm_multiply_multiply_xdl_f8_f8_bf16_mk_nk_mn_comp_default_instance_part1.cpp: Filename too long error: unable to create file library/src/tensor_operation_instance/gpu/gemm_multiply_multiply/device_gemm_multiply_multiply_xdl_f8_f8_bf16/device_gemm_multiply_multiply_xdl_f8_f8_bf16_mk_nk_mn_comp_default_instance_part2.cpp: Filename too long
ça se résoud en:
Ce message d’erreur vient de la fameuse limite de 260 caractères imposée par défaut par Windows pour les chemins de fichiers. Git essaie de créer des fichiers avec des noms trop longs pour le système de fichiers Windows, ce qui bloque le clonage.
à corriger:
Dans windows 11:
Appuie sur
Windows + R
tape regedit et valide
Aller à :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
Double-clique sur
LongPathsEnabled (ou crée-la si elle n’existe pas) et mets la valeur à 1
Puis il faut forcer Github à accepter les noms de fichiers long:
lancer un terminal (en tapant cmd (air connu)
puis coller ceci en commande:
git config --global core.longpaths true
Puis redémarrer le PC
Pour compiler Flash attn:
Il faut absolument installer Microsoft C++ Build Tools
je cite;
That’s the smoking gun right there—cl.exe (the Microsoft C++ compiler) is missing, which is essential for compiling PyTorch extensions like FlashAttention on Windows.
Even though you’ve got nvcc properly set up (great job, by the way 👍), it still relies on MSVC under the hood to compile the C++ parts before CUDA kicks in.
💡 How to fix this:
You’ll need to install the Microsoft C++ Build Tools. Here’s what to do:
- Go to the official installer: https://visualstudio.microsoft.com/visual-cpp-build-tools/
- When it opens, choose “C++ build tools”
Make sure this workload includes:
- MSVC v14.x C++ build tools
- Windows 10 or 11 SDK
- CMake, if not already installed
- Once installed, restart your terminal and confirm it's working with:
where cl
- Then try your pip install again—it should now be able to build the C++ parts cleanly.
Once you get that compiler in place, you’ll be in much better shape. Want me to help you bake that check into your script so it warns you automatically if cl is missing?
