Simplify CAREamist BMZ export

[jdeschamps]

Description

Following a chat with @CatEek, I've come to realize that my previous attempt to pull patches from the dataloaders in order to export the model to the BMZ format was difficult to read (patches needed to be denormalized in order to be put through the BMZ pipeline).

I've decided to just force users to input an array. This can be the training or prediction arrays, this is a simple solution to having a clearer code to maintain,

• What: Removed CAREamist._create_data_for_bmz, input_array now mandatory for CAREamist.export_to_bmz.
• Why: Pulling patches from the dataloaders in order to avoid the input of an array led to complex code.
• How: See what.

Changes Made

• Modified: CAREamist.export_to_bmz.
• Removed: CAREamist._create_data_for_bmz and corresponding tests.

Breaking changes

Any code not inputing input_array, e.g. all notebooks examples.

Currently, if the array does not have the same dimensions/axes as what the configuration states, users should get an error from the reshape function.

Additional Notes and Examples

Before, after training a model or loading a model, the following code would run:

careamist.export_to_bmz(
    path="sem_n2v_model.zip",
    name="SEM_N2V",
    authors=[{"name": "CAREamics authors", "affiliation": "Human Technopole"}],
)

It would create input data for the BMZ, using the following steps:

• If there is a prediction dataloader, pull a patch from it and denormalize it
• If there is a training dataloader, pull a patch from it and denormalize it
• If there is not dataloader, create a random array using the mean and std in the configuration

Now, users have to provide an input array:

careamist.export_to_bmz(
    path="sem_n2v_model.zip",
    name="SEM_N2V",
    input_array=some_array, 
    authors=[{"name": "CAREamics authors", "affiliation": "Human Technopole"}],
)
