我已經使用自制軟件安裝了ffmpeg。用matplotlib保存動畫?
但是我現在面臨的問題是運行腳本時不保存動畫。 我已經包含下面我的劇本和我的.bash_profile
import matplotlib
matplotlib.use('TKAgg')
import numpy as np
from matplotlib import pyplot as plt
from matplotlib import animation
# First set up the figure, the axis, and the plot element we want to animate
fig = plt.figure()
ax = plt.axes(xlim=(0, 2), ylim=(-2, 2))
line, = ax.plot([], [], lw=2)
# initialization function: plot the background of each frame
def init():
line.set_data([], [])
return line,
# animation function. This is called sequentially
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,
# call the animator. blit=True means only re-draw the parts that have changed.
anim = animation.FuncAnimation(fig, animate, init_func=init,
frames=200, interval=20, blit=True)
# save the animation as an mp4. This requires ffmpeg or mencoder to be
# installed. The extra_args ensure that the x264 codec is used, so that
# the video can be embedded in html5. You may need to adjust this for
# your system: for more information, see
# http://matplotlib.sourceforge.net/api/animation_api.html
anim.save('basic_animation.mp4', fps=30)
的.bash_profile
export PATH=$PATH:/$HOME/../../usr/local/Celler/ffmpreg/2.2.2/bin
export FFMPEG_BIN=/$HOME/../../usr/local/Cellar/ffmpeg/2.2.2/bin/
沒有錯誤?你確定你在正確的目錄中尋找輸出嗎? – tacaswell
會適用於我的路徑或我的PythonPath?我的路徑設置正確。 –
它將保存到運行代碼的python實例的cwd中 – tacaswell
