    25 avril 2011, par

    MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
    The zip file provided here only contains the sources of MediaSPIP in its standalone version.
    To get a working installation, you must manually install all-software dependencies on the server.
    If you want to use this archive for an installation in "farm mode", you will also need to proceed to other manual (...)

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Can't save matplotlib animation

    2 janvier 2020, par renger

    I am trying to get a simple animation saved using ffmpeg. I followed a tutorial to install ffmpeg, and I can now access it from the command prompt.

    Now I run this piece of code :

    import numpy as np
    
from matplotlib import pyplot as plt
    
from matplotlib import animation
    

    
fig = plt.figure()
    
ax = plt.axes(xlim=(0, 2), ylim=(-2, 2))
    
line, = ax.plot([], [], lw=2)
    

    
def init():
    
    line.set_data([], [])
    
    return line,
    

    
def animate(i):
    
    x = np.linspace(0, 2, 1000)
    
    y = np.sin(2 * np.pi * (x - 0.01 * i))
    
    line.set_data(x, y)
    
    return line,
    

    
anim = animation.FuncAnimation(fig, animate, init_func=init,
    
                               frames=200, interval=20, blit=True)
    

    
mywriter = animation.FFMpegWriter()
    
anim.save('mymovie.mp4',writer=mywriter)
    

    
plt.show()

    I get this error :

    Traceback (most recent call last):

WindowsError: [Error 2] Het systeem kan het opgegeven bestand niet vinden

    The last dutch sentence does mean something like : The system can’t find the specified file.

    What do these errors mean, and how can I solve them ?
