[question] There is no node able to be processed.

[EasonC13]

Describe the problem Originally I use the following command and it can work.

./meshroom_batch --input ../input_img --output output_obj

Now, I want my meshroom_batch use GPU to compute feature extraction to get better performance. I following this answer: https://github.com/alicevision/meshroom/issues/502#issuecomment-807130647

However, when I use

./meshroom_batch --input ../input_img --output output_obj --paramOverrides FeatureExtraction:forceCpuExtraction=0

It shows the following error:

[04:09:22.552032][warning] Some image(s) have no serial number to identify the camera/lens device.
This makes it impossible to correctly group the images by device if you have used multiple identical (same model) camera devices.
The reconstruction will assume that only one device has been used, so if 2 images share the same focal length approximationthey will share the same internal camera parameters.
333 image(s) are concerned.

Want to know how to do feature extraction via command line in Mushroom in GPU. Should I set up a node?

Hi. It's been a while but were you able to make any progress with this?
