[RxR-Habitat] How to export a robot navigation video based on a baseline

[2201957]

Could you provide me with the code in the image above "Generate a video of a robot navigating with natural language guidance based on baseline"?

[jacobkrantz]

You can use config options to generate a video during evaluation:

VLN-CE/vlnce_baselines/config/default.py

Lines 23 to 24 in 2375f18

	_C.VIDEO_OPTION = [] # options: "disk", "tensorboard"
	_C.VIDEO_DIR = "data/videos/debug"

If you want to update the way in which frames are produced, you can modify/replace the functions in https://github.com/jacobkrantz/VLN-CE/blob/master/habitat_extensions/utils.py

Custom elements in the above videos (arrows, additional text) were added using opencv utilities.

Hi @jacobkrantz what can be reason for not getting a robot navigating video even after make changes to the [default.py](vlnce_baselines/config/default.py) as follows:

_C.VIDEO_OPTION = ["disk"]  # options: "disk", "tensorboard" 
 _C.VIDEO_DIR = "data/videos/debug" 

Do we need to make any others changes?
One more question, what's the difference between using 'disk' and 'tensorboard' and how can they be accessed?

Solved it. Thank you!

嗨，即使在更改 [default.py]（vlnce_baselines/config/default.py） 后仍无法获取机器人导航视频的原因是什么：

_C.VIDEO_OPTION = ["disk"]  # options: "disk", "tensorboard" 
 _C.VIDEO_DIR = "data/videos/debug" 

我们是否需要进行任何其他更改？还有一个问题，使用“disk”和“tensorboard”有什么区别，如何访问它们？

解决了它。谢谢！

How did you solve this problem, and what changes are still needed? I really want to reproduce
