blosc2 seems to require python>=3.11

[scarere]

Blosc2>=3.0.0b1 seems to have been added as a dependency in nnunetv2==2.6.0. The pyproject.toml still says the nnunetv2 supports python3.10 however the new blosc2 requirement seems to require python>=3.11

"blosc2>=3.0.0b1"

@scarere It does appear 3.0.0b1 specified Python >=3.10.

It appears 3.0.0rc1 specified the bump to Python 3.11.

My bad it seems the issue is related to the acvl-utils dependency, which in turn depends on blosc2 which further in turn depends on python>=3.11. My project uses poetry for dependency management. Defining the only 2 requirements as python >=3.1.0,<3.11 and nnunetv2>=2.6.0 results in the following output.

The current project's supported Python range (>=3.10.0,<3.11) is not compatible with some of the required packages Python requirement:
  - blosc2 requires Python >=3.11, so it will not be satisfied for Python >=3.10.0,<3.11
  - blosc2 requires Python >=3.11, so it will not be satisfied for Python >=3.10.0,<3.11
  - blosc2 requires Python >=3.11, so it will not be satisfied for Python >=3.10.0,<3.11
  - blosc2 requires Python >=3.11, so it will not be satisfied for Python >=3.10.0,<3.11

    Because no versions of acvl-utils match >0.2.3,<0.2.4 || >0.2.4,<0.2.5 || >0.2.5,<0.3
 and acvl-utils (0.2.3) depends on blosc2 (>=3.0.0b4), acvl-utils (>=0.2.3,<0.2.4 || >0.2.4,<0.2.5 || >0.2.5,<0.3) requires blosc2 (>=3.0.0b4).
(1) So, because acvl-utils (0.2.4) depends on blosc2 (>=3.0.0b4)
 and acvl-utils (0.2.5) depends on blosc2 (>=3.0.0b4), acvl-utils (>=0.2.3,<0.3) requires blosc2 (>=3.0.0b4).

    Because no versions of blosc2 match >=3.0.0b4,<3.0.0 || >3.0.0,<3.1.0 || >3.1.0,<3.1.1 || >3.1.1,<3.2.0 || >3.2.0
 and blosc2 (3.0.0) requires Python >=3.11, blosc2 is forbidden.
    And because blosc2 (3.1.0) requires Python >=3.11, blosc2 is forbidden.
    And because acvl-utils (>=0.2.3,<0.3) requires blosc2 (>=3.0.0b4) (1), acvl-utils (>=0.2.3,<0.3) requires blosc2 (3.1.1 || 3.2.0)
    And because blosc2 (3.2.0) requires Python >=3.11
 and blosc2 (3.1.1) requires Python >=3.11, acvl-utils is forbidden.
    Because no versions of nnunetv2 match >2.6.0,<3.0.0
 and nnunetv2 (2.6.0) depends on acvl-utils (>=0.2.3,<0.3), nnunetv2 (>=2.6.0,<3.0.0) requires acvl-utils (>=0.2.3,<0.3).
    Thus, nnunetv2 is forbidden.
    So, because fl4health depends on nnunetv2 (^2.6.0), version solving failed.
