`f"{req.project_name}{req.specifier}"` is more generic than `f"{req.project_name}{req.specs[0][0]{req.specs[0][1]}"`. Either solution fix the issue.
#253 Dependency record is not required by Bioimage.IO. Use `generate_default_deps=False` in `export_bioimageio()` by default to streamline the export process and enhance clarity for new users.
In some cases need to add extra context to prevent overlapping write regions of non-neighboring blocks. Cf. https://forum.image.sc/t/trouble-using-stardist-predict-instances-big/88871/6
windows-latest with tensorflow 2.15.0 yields different results ¯\_(ツ)_/¯
Negative values in label masks will turn off all losses for that pixel during training. This is especially useful for training with sparse annotations, i.e. not all pixels of an image have to be annotated. This is similar to https://github.com/ksugar/stardist-sparse, but all negative label pixels are ignored (not just -1), and the object classification loss is also disabled (if 'n_classes' is not None).
To disregard pixels that have been intentionally set to -1
Fix and improve the export function for Bioimage.IO
- Requires Keras 3-ready csbdeep package (to be released) - Use abstracted BACKEND to replace keras.backend Work in progress...
Seems like Keras 3 is more strict about some mixed data type arithmetic operations -> cast ground truth and intermediate variables to float data type. Not all of these casts are likely necessary, but they shouldn't hurt either.
The parameters "workers" and "use_multiprocessing" have moved from `model.fit` to the data generator (based on `keras.utils.PyDataset`). Also, the data generator apparently must return tuples (and not lists)? -> https://stackoverflow.com/a/78158487
Model export seemingly not possible with Keras 3.
Python 3.12 apparently removed distutils
No longer use environment variable SETUPTOOLS_USE_DISTUTILS, which doesn't work with Python 3.12. Don't remember why we had to add this in the first place...
Return lists in data generator
numpy.distutils has been removed in Python 3.12 https://numpy.org/doc/stable/reference/distutils_status_migration.html#distutils-status-migration
Add support for Keras 3
