Question

尝试创建动画并将其保存到文件时，我收到了该错误。

我的代码：

def animate_scatter(x_val, y_val, z_vals,
                        divisions, name, z_max, z_min, units, radius):
    """
    Specific animator.
    """
    try:
        z_val = decompress(z_vals.pop(0), level=settings.medium_comp_level)
    except IndexError:
        return
    plt.cla()
    plt.clf()
    rad = float(radius*1.3)/divisions
    size = (rad/4)**2
    x_min = min(x_val)-rad*1.1
    x_max = max(x_val)+rad*1.1
    y_min = min(y_val)-rad*1.1
    y_max = max(y_val)+rad*1.1
    plt.xlim((x_min, x_max))
    plt.ylim((y_min, y_max))
    #plt.suptitle(name)
    plt.scatter(x_val, y_val, s=size, c=z_val, marker='s',
                vmin=z_min, vmax=z_max)
    plt.gca().invert_yaxis()
    cb = plt.colorbar()
    plt.xlabel("x [pixels]")
    plt.ylabel("y [pixels]")
    cb.set_label(units)

def create_scatter_animation(x_val, y_val, z_vals_avg, divisions, z_max, z_min, units, name, radius=800, fps=15):
    """
    Creates animation from data.
    """
    fig = plt.figure()
    frames = len(z_vals_avg)
    def animate(dummy_frame):
        """
        Wrapper.
        """
        animate_scatter(x_val, y_val, z_vals_avg,
                            divisions, name, z_max, z_min, units, radius)
    anim = animation.FuncAnimation(fig, animate, frames=frames)
    anim.save(name, writer=WRITER, fps=fps)


def import_and_plot(source, radius=None, level=9):
    """
    Imports data from a compressed file and plots it.
    """
    src = open(source, 'r')
    values = decompress(src.read(), level=level)
    #[x_val, y_val, z_vals_avg, divisions, z_max, z_min, units]
    x_val, y_val, z_vals_avg = values[0], values[1], values[2]
    divisions = values[3]
    z_max, z_min = values[4], values[5]
    units = values[6]
    src.close()
    create_scatter_animation(x_val, y_val, z_vals_avg, divisions, z_max, z_min, units, source)

输出：

IOError: [Errno 32] Broken pipe

我在"IOError: [Errno 32] Broken pipe" when saving animation files in anaconda python尝试过解决方案但它对我不起作用。我也在ubuntu中使用anaconda。

_writer = animation.writers['ffmpeg']
WRITER = _writer(fps=15, metadata=dict(artist='name'), bitrate=1800)

matplotlib动画IOError [Error32]管道损坏（使用anaconda）
