Hello everyone

I have tried all the steps one by one but all the time i am receiving the same error , i have tried with all image formats but still the issue is same can you please help me in that , I am running this code in colab.

[11:38:41.909878][warning] Image 'shirt0_b.jpg' focal length (in mm) metadata is missing.
Can't compute focal length (px), use default.

[11:38:41.910090][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 approximation they will share the same internal camera parameters.
1 image(s) are concerned.
