This pull request focuses on refactoring the dependency check mechanism and simplifying the codebase by removing redundant imports and functions. The primary changes involve updating the import logic for various dependencies and cleaning up the code by removing unused functions.
Refactoring and simplification:
brainpy/_src/dependency_check.py
: Removed multiple functions related to importing and checking dependencies (import_numba
,import_cupy
, etc.), and replaced them with a more streamlined approach usingimportlib.util.find_spec
to check for module availability. [1] [2] [3]brainpy/_src/dnn/linear.py
: Updated the import logic fortaichi
andbraintaichi
to use the new streamlined approach. Removed checks fornumba
andcupy
dependencies. [1] [2] [3] [4]brainpy/_src/math/defaults.py
: Removed the import oftaichi
and associated type definitions (ti_int
,ti_float
). [1] [2]brainpy/_src/math/environment.py
: Removed the import oftaichi
and associated logic for settingti_float
andti_int
types. [1] [2] [3]brainpy/_src/math/event/csr_matmat.py
: Simplified imports and removed redundant code.brainpy/_src/math/event/csr_matvec.py
: Simplified imports and removed redundant code.
