Building Docker image fails

[jonatan-ivanov]

Describe the bug
Since Docker images are unavailable, I tried to build them, using the command in the docs but the build fails.

To Reproduce
Follow what the docs says and try to build the image:

git clone https://github.com/birdnet-team/BirdNET-Analyzer.git
cd BirdNET-Analyzer
docker build -t birdnet-analyzer .

Especially this:

37.66 ERROR: No matching distribution found for tensorflow-cpu>=2.20

Expected behavior
Being able to build the docker image running docker build.

Screenshots
N/A

Desktop (please complete the following information):

• OS: macOS
• Version 26.5.2 arm64

Additional context
I can build the image for the 2.4.0 release:

# clone first
git checkout v2.4.0
git switch -c 2.4.0 # so we won't have a detached HEAD
docker build -t birdnet-analyzer .

#961 was merged recently which seems to be connected since it is forcing the version of tensorflow-cpu that the build also have a problem with:

37.66 ERROR: No matching distribution found for tensorflow-cpu>=2.20
