在我的macOS v 10.11.6上，我在jupyter笔记本上运行moviepy时遇到错误 Python v 3.5.2 Conda v 4.3.8 Jupyter 4.2.1
我导入并运行一个简单的单元格：
from moviepy.editor import VideoFileClip
from IPython.display import HTML
new_clip_output = 'test_output.mp4'
test_clip = VideoFileClip("test.mp4")
new_clip = test_clip.fl_image(lambda x: cv2.cvtColor(x, cv2.COLOR_RGB2YUV)) #NOTE: this function expects color images!!
%time new_clip.write_videofile(new_clip_output, audio=False)
错误是：
TypeError Traceback (most recent call last)
<ipython-input-8-27aee53c99d8> in <module>()
1 new_clip_output = 'test_output.mp4'
--> 2 test_clip = VideoFileClip("test.mp4")
3 new_clip = test_clip.fl_image(lambda x: cv2.cvtColor(x, cv2.COLOR_RGB2YUV)) #NOTE: this function expects color images!!
4 get_ipython().magic('time new_clip.write_videofile(new_clip_output, audio=False)')

是不是因为各种库的版本存在冲突？
