Version 2.0.0 runs slowly

[Anqi00]

When I switched to version 2.0.0, the multi-camera matching issue was resolved by adding parameters.
general:
camera_model: "opencv"
single_camera: false

0: DJI Drone

cam0:
camera_model: "opencv"
intrinsics: ~
images: "*.JPG"

1: Azure Kinect

cam1:
camera_model: "opencv"
intrinsics: [
894.637116, 894.415775, 943.383850, 563.671383,
0.078929, -0.045787, 0.003979, -0.002581
]
images: "*.png"

However, I encountered a new problem when I ran python -m deep_image_matching --dir assets/orchard --pipeline superpoint+lightglue --camera_options config/my_cameras.yaml --tiling When running the preselection command, it runs very, very slowly, as if stuck, after displaying "Deep Image Matching loaded in 2.728 seconds." I used all the default settings.
But this doesn't happen when using the old version. What's the reason?

Good that the camera loading is solved. For the new issue, please could you post the complete command that you have run please? In alternative I also suggest to run the code in the new proposed way running ./demo.py, just properly changing:

args = {
    "dir": "./assets/example_cyprus",
    "pipeline": "superpoint+lightglue",
    "strategy": "bruteforce",
    "quality": "medium",
    "tiling": "none",
    "camera_options": "./assets/example_cyprus/cameras.yaml",
    "openmvg": None,
    "force": True,  # Remove existing features and matches
}

Let me know if you still encounter the issue

When I modify the args content as follows:
args = {
"dir": "./assets/orchard2",
"pipeline": "superpoint+lightglue",
"strategy": "bruteforce",
"quality": "medium",
"tiling": "none",
"camera_options": "./config/my_cameras.yaml",
"openmvg": None,
"force": True, # Remove existing features and matches
}
The output after 10 minutes is still the same:

And the same is true when running the example data.

With the same input parameters, what is the difference in execution time between versions 1.3 and 2.0?

[Anqi00]

In version 2.0 or the dev branch of version 1.3, for example, the first run goes smoothly, taking about 1 minute. The second run of the same command and the same dataset takes 10 minutes or more, and the third run may take 1 minute or 30 minutes.

"Deep Image Matching loaded in 2.715 seconds.
PNG file does not have exif data."
Sometimes there's a long delay between these two output lines. Is this process extracting the camera's intrinsic parameters?

[lcmrl]

Ok thanks for reporting. Are you on linux or windows? How many images are you processing and which is the resolution? I also had some delays but never so long, I'll look into it. Clearly if you also want to have a look feel free =)

[Anqi00]

I am using Linux, and there are 6 pictures in total, five of which are 4k resolution and one is 2k resolution.

Hi, I was not able to replicate the issue, do you still have this issue? Or did you solve in any way?
