chore: Fix Pixano deployed app

[cpvannier]

Description

With the merge of Pixano Annotator and Explorer in #23 and #27, and the use of svelteKit with the new ImageWorkspace, running the Pixano deployed app is not yet working and needs to be fixed.

Warning: breaking change for local run

To run the backend locally you should now use LIBRARY_DIR instead of DATA_DIR (and pixano.app instead of pixano.apps as of #27):

LIBRARY_DIR=your_datasets_directory/ uvicorn pixano.app:create_app --factory --reload

And S3 parameters are now named:

• endpoint_url
• region_name
• aws_access_key
• aws_secret_key
• local_model_dir

Using S3 datasets

For datasets on S3 storage, you can add the required parameters similarly to LIBRARY_DIR:

LIBRARY_DIR=my_s3_path ENDPOINT_URL=aws AWS_ACCESS_KEY=password uvicorn pixano.app:create_app --factory --reload

For the deployed app installed with PyPI, LIBRARY_DIR is an argument while S3 parameters are options added to the command with --{option_name}:

Usage: pixano [OPTIONS] LIBRARY_DIR

  Launch Pixano App in LIBRARY_DIR

  LIBRARY_DIR is the local or S3 path to your dataset library

Options:
  --endpoint_url TEXT     S3 endpoint URL, use 'AWS' if not provided.
                          Used if library_dir is an S3 path
  --region_name TEXT      S3 region name, not always required for private
                          storages. Used if library_dir is an S3 path
  --aws_access_key TEXT   S3 AWS access key. Used if library_dir is an S3
                          path
  --aws_secret_key TEXT   S3 AWS secret key. Used if library_dir is an S3
                          path
  --local_model_dir TEXT  Local path to your models. Used if library_dir
                          is an S3 path
  --host TEXT             Pixano app URL host  [default: 127.0.0.1]
  --port INTEGER          Pixano app URL port  [default: 0]
  --help                  Show this message and exit.

For example:

pixano my_s3_path --endpoint_url aws --aws_access_key password

Changes

Fixed

• Fix build paths for Pixano app
• Fix getting Pixano app settings with lru_cache for deployed app and unit tests
• Fix accessing S3 dataset settings in deployed app
• Remove outdated comment
• Revert lancedb and pylance versions to older versions to prevent issues with some datasets (pixano/pixano-project-manager#8)
