TypeError: must be real number, not NoneType when writing with moviepy

[mjedmonds]

I receive the following error using the demo. I'll try to resolve myself, and update the issue if I find a fix.

python visualize.py --song beethoven.mp3 --duration 15 --resolution 128

Were you able to find the fix for this?

[mjedmonds]

I was not unfortunately. I didn't spend much time on it though…so may be possible with relatively little effort.

Oh okay, i have been at it for the entire day, still no luck

I re-installed moviepy and that seemed to get rid of this error for me, running Python 3.6.8 on W10

pip3 install moviepy

Reinstalling doesn't work either, and the problem still occurs on Spyder

I know I am late but for the sake of someone else: If you have JUST installed pip3 install moviepy make sure to restart the kernel if you are on Juypter notebook otherwise you will keep getting TypeError: must be real number, not NoneType

YOU SAVED MY DAY

我知道我迟到了，但为了其他人：如果您刚刚安装，pip3 install moviepy请确保重新启动内核（如果您使用的是 Juypter 笔记本），否则您将不断收到TypeError: must be real number, not NoneType

牛牛牛
