@esc , In the Numba survey, there was a question regarding the features that you find important. One of them was โ€œGet Numba signatures from Python type annotations.โ€ If I understand the concept correctly, this feature is closely linked with ahead-of-time compilation and explicit caching. I assume this feature could make Numba type hinting redundant. A critical condition for its implementation would be enabling numpy typing to specify array dimensions. This will hopefully be possible in future numpy versions. The idea would be that Numba could automatically infer signatures from Python type annotations and apply them automatically, which would be an excellent addition. Is this the case? ```auto # *************************************************************************** # Present # *************************************************************************** import numpy as np from numpy.typing import NDArray from numba.pycc import CC type ArrFloat = NDArray[np.float32] | NDArray[np.float64] cc = CC('my_module') @cc.export('mult2df64', 'float64[:,:](float64[:,:], float64[:,:])') @cc.export('mult2df32', 'float32[:,:](float32[:,:], float32[:,:])') @cc.export('mult1df64', 'float64[:](float64[:], float64[:])') @cc.export('mult1df32', 'float32[:](float32[:], float32[:])') def mult(a: ArrFloat, b: ArrFloat) -> ArrFloat: return a * b if __name__ == " __main__": cc.compile() # *************************************************************************** # Future (Get Numba signature from Python type annotations) # *************************************************************************** import numpy as np from numpy.typing import NDArray from numba import aot aot.infer_python_signature = True type Float = np.float32 | np.float64 type ArrFloat = NDArray[Float, ndim=1] | NDArray[Float, ndim=2] @aot def mult(a: ArrFloat, b: ArrFloat) -> ArrFloat: return a * b if __name__ == " __main__": aot.compile() ``` ---

@Oyibo yes, that is indeed the case. The narrative here is that, since Python is now equipped with typing abilities, it would be quite neat for Numba to leverage those. ---
