Install local version of Haystack's Annotation Tool

Although the instructions in Haystack describe how to install the annotation tool locally using Docker, all attempts have failed. Unfortunately, the website does not contain any more details.

Has anyone been able to get this to work? If so, what am I missing?

Reproduction scenario:

• git clone https://github.com/deepset-ai/haystack.git
• cd haystack
• python -m pip install -e '.[all-gpu]' # I used the latest version to develop a project and, now, I want to use the annotation tool to create a custom dataset, thus the following checkout to an older release.
• git checkout v1.26.x
• docker-compose pull
• I left the docker-compose.yml as is:

All credits to @Stefano Fiorucci - anakin87 for the solution to this problem.

The complete steps are:

1. git clone https://github.com/deepset-ai/haystack.git
2. cd ./haystack
3. python -m pip install -e '.[all]' or '.[all-gpu]' # Use the latest version to develop the project and checkout to the latest 1x release to use the annotation tool.
4. git checkout v1.26.x # Do NOT execute python -m pip install again.
5. cd ./annotation_tool/
6. edit docker-compose.yml # Configure the credentials and the database in ./haystack/annotation_tool/docker-compose.yml (see OP link for the original version of the file). In this case I left everything as is, but uncommented lines 12 - 16.
7. Add a new user group to the annotation/ directory, in windows, so that Docker can have the privileges to create directories and files. Follow these steps here.
8. docker-compose pull # execute this command inside the annotation_tool/ directory.
9. docker-compose up
10. Chrome browser: http://localhost:7001
