Wrong Python version causing Attribute Error is_integer() in utils.py

[taesuhpark]

tunix/pyproject.toml

Line 8 in 3b55852

requires-python = ">=3.11"

This version should be set to '>=3.12' (or higher) at least, because tunix/tunix/rl/utils.py calls value.is_integer() which is safely supported for the base int type since Python v3.12. For example, see below:

tunix/tunix/rl/utils.py

Line 37 in 3b55852

if value is not None and (not value.is_integer() or value <= 0):

I tested it with v3.11 and confirmed it causes Attribute Error. You should upgrade the default Python version to 3.12 (or higher) in pyproject.toml or substitute all value.is_integer() with the more primitive and safe isinstance().

Related to #902. A PR #903 has been opened to fix this issue.

One more warning: Installation from source using pip install -e ".[dev]'" causes a build failure with dt-tree when using Python 3.14 or higher. I strongly recommend to set requires-python = "==3.13" for guaranteed installation. In summary:

• v3.11 has an issue with is_ineger() which is valid only with v3.12 or later according to Python release note.
• v3.12 (not tested)
• v3.13 ok
• v3.14 experienced a build failure with dt-tree when tried installation from source.
