  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • matplotlib ArtistAnimation returns a blank video

    28 mars 2017, par Mpaull

    I’m trying to produce an animation of a networkx graph changing over time. I’m using the networkx_draw utilities to create matplotlib figures of the graph, and matplotlib’s ArtistAnimation module to create an animation from the artists networkx produces. I’ve made a minimum reproduction of what I’m doing here :

    import numpy as np
    
import networkx as nx
    
import matplotlib.animation as animation
    
import matplotlib.pyplot as plt
    

    
# Instantiate the graph model
    
G = nx.Graph()
    
G.add_edge(1, 2)
    

    
# Keep track of highest node ID
    
G.maxNode = 2
    

    
fig = plt.figure()
    
nx.draw(G)
    
ims = []
    

    
for timeStep in xrange(10):
    

    
    G.add_edge(G.maxNode,G.maxNode+1)
    
    G.maxNode += 1
    

    
    pos = nx.drawing.spring_layout(G)
    
    nodes = nx.drawing.draw_networkx_nodes(G, pos)
    
    lines = nx.drawing.draw_networkx_edges(G, pos)
    

    
    ims.append((nodes,lines,))
    
    plt.pause(.2)
    
    plt.cla()
    

    
im_ani = animation.ArtistAnimation(fig, ims, interval=200,            repeat_delay=3000,blit=True)
    
im_ani.save('im.mp4', metadata={'artist':'Guido'})

    The process works fine while displaying the figures live, it produces exactly the animation I want. And it even produces a looping animation in a figure at the end of the script, again what I want, which would suggest that the animation process worked. However when I open the "im.mp4" file saved to disk, it is a blank white image which runs for the expected period of time, never showing any of the graph images which were showed live.

    I’m using networkx version 1.11, and matplotlib version 2.0. I’m using ffmpeg for the animation, and am running on a Mac, OSX 10.12.3.

    What am I doing incorrectly ?

  • ffmepg suddently stopped working

    30 octobre 2013, par jdartland

    Hi Im using ffmpeg jwplayer to handle my video uploads. It worked just fine untill I added a video upload to a new model. My video files gets uploaded to the database but i can't play them in my jwplayer. I also noticed that ffmpeg converts files to avi eaven though I've specifyed it in both of my models to convert files into flv.

    Here is my javascrip "error" :

    Error loading player:
    
No playable sources found.

    My models, tabels and vews shuld work cus I haven't changed anything in my old working post module.

    Here is whats happening in the upload :

  • Error audio loading when runing Whisper Open AI model

    9 juin 2024, par John mick

    The problem I'm trying to solve is that I can't run Whisper model for some audio, it says something related to audio decoding.

    


    payload.wav: Invalid data found when processing input.
raise RuntimeError(f"Failed to load audio: {e.stderr.decode()}") from e


    


    I tried using the micro-machines.wav and it works fine but when i used other audio it gives me an error.

    


    import whisper

model = whisper.load_model("base")
text=model.transcribe('micro-machines.wav',fp16=False)
print(text)
text=model.transcribe('payload.wav',fp16=False)
print(text)


    


    Error I'm getting for payload :
