The file superpoint.py included in the repo contains the following license.

I do not believe this file can be legally included in an Apache 2.0 licensed project.

From the README:

SuperPoint follows a different, restrictive license (this includes its pre-trained weights and its inference file)

In this repo, the Apache 2.0 license applies to files that do not include a different license notice in their header.

Thanks for the clarification. So there are three licenses at play here.

• License 1: The Apache 2.0 License which applies to files in the repo, unless otherwise specified in the particular file.
• License 2: The actual license that applies to the superpoint code, which is mentioned in the README and points to an external repository, and which you have linked above.
• License 3: The license that appears in superpoint.py which is quite a bit more restrictive than the above license.

License 3 (superpoint.py) states

ANY REPRODUCTION, MODIFICATION, DISTRIBUTION, PUBLIC PERFORMANCE, OR PUBLIC DISPLAY OF OR THROUGH USE OF THIS SOURCE CODE WITHOUT THE EXPRESS WRITTEN CONSENT OF COMPANY IS STRICTLY PROHIBITED

License 2 gives an academic license. Can you confirm that I should ignore License 3 and consider License 2 to be the one to apply to the superpoint.py file? In that case, would it be okay to copy-paste License 2 over License 3 in my local repository?

[sarlinpe]

The file superpoint.py is copied verbatim from the original repo. I am not a lawyer so I am unable to comment on whether License 2 or 3 applies.

I understand, thank you. To stay on the safe side, I will just delete that file from my local repo.
