Visualise Data

[MZ82020]

I have a question regarding visualization. I don't understand why when I launch the visualization I always get this. I had the data prepared properly. But I don't understand why these messages! please explain to me?

And, when I run your code '' vis_multifuture_trajs_video.py'' ,there happened the follow problem: File "code/vis_multifuture_trajs_video.py", line 85, in raise Exception("Cannot open %s" % video_file) Exception: Cannot open forking_paths_dataset/multifuture_visualization/0000_0_303_cam1.mp4

I don't understand why!

I got in multifutur_visualizations 507 elements (but photos with a bbox only without the possible multifutur paths in green as mentioned!).

Exemple:

And in rgb videos I have 3000 videos.

Thanks!

Are the videos put under "forking_paths_dataset/multifuture_visualization/"?

@JunweiLiang yes!

@JunweiLiang What can I do to solve this problem please ??

@MZ82020 The warnings are normal. That is due to the video encoding missing some frames at the end of the video. And I follow my instructions to generate the visualization and they work fine. I'm guessing you are missing a step according to here.

@MZ82020 Hi, I have the same problem as you, have you solved it?

[Jctrp]

I ''Cannot open forking_paths_dataset/multifuture_visualization/0000_29_420_cam3.mp4''

OK, I finally found what was the problem. It's because of the lack of ffmeg module in my new virtual environment. Hope it is useful for all guys who have the same question as me.

Closing for now.
