Entry from Librosa to Dedian

[Nilsonfsilva]

hello
It is with great pleasure that I would like to inform you that Librosa is being packaged to become part of the debian project.

To adapt the Librosa project to Debian's policies, I had to make a patch disabling both the tests and the docs/examples directory.

Both have the "data" directory, which is missing from the project repository.

From what I've seen, the "data" directory is in a separate repository. https://github.com/librosa/librosa-test-data.

If you are interested in the librosa project package in its entirety, enter a license.

Thanks!

Thanks for this. A few comments/questions:

• I'm curious why you need to make a patch rather than omitting those parts of the repository from the package manifest?

• I would also suggest that either the docs directory is included entirely or not at all. If you remove the examples directory, the documentation will not build properly.

• The docs/examples directory does not include a "data" directory. Do you mean audio? Again, this is necessary for the documentation to build correctly, at least for the html build target. If you're building manpage targets for docs, it might not be necessary (I haven't tried).

• I'm not sure I understand your last comment. We already have a license file in the package. Or are you asking me to add a license file to the test-data repository? I don't think it's necessary to include in a deb package (the resulting archive would be huge!), but you're right that that repo probably should have a license file in it.

Hi Brian McFee!
First of all, all my effort in packaging librosa is because I think that a project like yours deserves to be in our repositories.

I will try to answer your questions:

'm not sure I understand your last comment. We already have a license file in the package. Or are you asking me to add > a license file to the test-data repository? I don't think it's necessary to include in a deb package (the resulting archive
would be huge!), but you're right that that repo probably should have a license file in it.
The librosa is under license, the repository "data" is not.

Per Debian's packaging policy, we can only package any file in a repository that is under license.
If the "data" directory were inside the librosa repository, there would be no problem. Two possible solutions: either the "data" directory is copied into librosa, or a license can be added to the repository "data".

The docs/examples directory does not include a "data" directory. Do you mean audio?

sorry for the mistake. Yes I meant "audio

Again, this is necessary for the documentation to build correctly, at least for the html build targe.

yes the goal is to create html pages.
the issue of documentation it is also showing errors. I think it has to do with the new updates to the "numba " and "numpy" library. We had some issues with some packages that numba and numpy are necessary.
I don't know if this is the case with librosa.

sorry for the mistake. Yes I meant "audio

Again, this is necessary for the documentation to build correctly, at least for the html build targe.

yes the goal is to create html pages.

Got it. To be clear, the tests/data folder is only needed for running the unit tests, and is not needed at runtime or for building the docs. Unless there's specific debian policy on executing unit tests for packages, I don't think it's necessary to include it.

The docs/examples/audio/ folder is necessary for building HTML docs, and there is in fact already a license (CC-BY) for the files in question there (see README.md). Since this is already included in the repo, I don't see any problem here either.

For the doc build issues, it kind of looks like you have a very old numpy installation:

AttributeError: module 'numpy' has no attribute 'float'

It would be most helpful if you could report the versions of the doc build dependencies here. See:
