Migrate to NumPy 2.x.x and raise minimum Python version to 3.10

[muhammad-fiaz]

Hello!

I have updated the project to be compatible with NumPy 2.0 (minimum supported version) and raised the minimum required Python version to 3.10 to ensure consistent dependency resolution when using uv.

NumPy Compatibility

• I updated the project’s NumPy requirement to ensure compatibility with NumPy 2.0 and later.
• I replaced deprecated np.bool with np.bool_ .
• Ruff plugin NPY201

Python Version Requirement

* I raised the minimum supported Python version to 3.10

• Python versions below 3.10 cannot satisfy NumPy’s dependency constraints when resolving environments with uv.

  × No solution found when resolving dependencies for split (markers: python_full_version == '3.8.*'):
  ╰─▶ Because the requested Python version (>=3.8) does not satisfy Python>=3.9.0 and numpy>=1.26.0,<=1.26.1 depends on     
      Python>=3.9,<3.13, we can conclude that numpy>=1.26.0,<=1.26.1 cannot be used.
      And because only the following versions of numpy are available:
          numpy<=1.26.0
          numpy==1.26.1
          numpy==1.26.2
          numpy==1.26.3
          numpy==1.26.4
          numpy==2.0.0
          numpy==2.0.1
          numpy==2.0.2
          numpy==2.1.0
          numpy==2.1.1
          numpy==2.1.2
          numpy==2.1.3
          numpy==2.2.0
          numpy==2.2.1
          numpy==2.2.2
          numpy==2.2.3
          numpy==2.2.4
          numpy==2.2.5
          numpy==2.2.6
          numpy==2.3.0
          numpy==2.3.1
          numpy==2.3.2
          numpy==2.3.3
          numpy==2.3.4
          numpy==2.3.5
          numpy==2.4.0
          numpy==2.4.1
      we can conclude that numpy>=1.26.0,<1.26.2 cannot be used. (1)

      Because the requested Python version (>=3.8) does not satisfy Python>=3.9.0 and numpy>=1.26.2,<=2.0.2 depends on      
      Python>=3.9, we can conclude that numpy>=1.26.2,<=2.0.2 cannot be used.
      And because we know from (1) that numpy>=1.26.0,<1.26.2 cannot be used, we can conclude that numpy>=1.26.0,<2.1.0     
      cannot be used. (2)

      Because the requested Python version (>=3.8) does not satisfy Python>=3.9.0 and numpy>=2.1.0,<=2.2.6 depends on       
      Python>=3.10, we can conclude that numpy>=2.1.0,<=2.2.6 cannot be used.
      And because we know from (2) that numpy>=1.26.0,<2.1.0 cannot be used, we can conclude that numpy>=1.26.0,<2.3.0      
      cannot be used. (3)

      Because the requested Python version (>=3.8) does not satisfy Python>=3.9.0 and all of:
          numpy>=2.3.0,<=2.3.5
          numpy>=2.4.1
      depend on Python>=3.11, we can conclude that all of:
          numpy>=2.3.0,<=2.3.5
          numpy>=2.4.1
       cannot be used.
      And because we know from (3) that numpy>=1.26.0,<2.3.0 cannot be used, we can conclude that all of:
          numpy>=1.26.0,<2.4.0
          numpy>2.4.0
       cannot be used.
      And because numpy==2.4.0 was yanked (reason: Backward compatibility bug), we can conclude that numpy>=1.26.0 cannot   
      be used.
      And because your project depends on numpy>=1.26 and your project requires sam3[dev], we can conclude that your        
      project's requirements are unsatisfiable.

      hint: Pre-releases are available for `numpy` in the requested range (e.g., 2.4.0rc1), but pre-releases weren't        
      enabled (try: `--prerelease=allow`)

      hint: The `requires-python` value (>=3.8) includes Python versions that are not supported by your dependencies        
      (e.g., numpy>=1.26.0,<=1.26.1 only supports >=3.9, <3.13). Consider using a more restrictive `requires-python` value  
      (like >=3.9, <3.13).

      hint: While the active Python version is 3.14, the resolution failed for other Python versions supported by your      
      project. Consider limiting your project's supported Python versions using `requires-python`.

• I ran Ruff with the NPY201 rule and verified that all checks pass.
• I confirmed that uv sync --dev completes successfully with the updated constraints.

these changes follows the official NumPy 2.0 migration guide.

please tell me, if there any additional changes needed!

This PR looks quite obviously LLM-generated. Looking at some other merged PRs like #137 it seems they have much more succinct descriptions. Consider writing the words with your human hands rather than the LLM.

Hello, @tamird first look at the actual changes made in this PR rather than judging based on the description alone. This PR only contains a minor version update along with a small API syntax compatibility change, and the implementation was done manually. btw I even added reference citation links to clearly show the related changes and sources :)

Optional: if anyone would like to try these changes before the PR is merged, you can install them directly from my fork:

pip install git+https://github.com/muhammad-fiaz/sam3.git@main

or

This includes the NumPy 2.x compatibility updates and the Python 3.10+ requirement introduced by this PR.
