visualization

[Kamel-schbock]

Hey, I run training, test, validation successfully. But when i run visualize.py i got the following error:

Video creation for sequence00000 is starting... MovieWriter ffmpeg unavailable; trying to use <class 'matplotlib.animation.PillowWriter'> instead. Traceback (most recent call last): File "/home/user/anaconda3/lib/python3.7/site-packages/PIL/Image.py", line 2114, in save format = EXTENSION[ext] KeyError: '.mp4'

During handling of the above exception, another exception occurred:
