Some more possibilities:
# The following does not work in lpython (Issue #2492)
# A_nm: i16[n, m] = empty((n, m), dtype=int16)
# doesn't work
# A_nm : i16[:] = empty((n, m), dtype=int16)
# works!
A_nm : Allocatable[i16[:]] = empty((n, m), dtype=int16)
The following produces an unhandled exception
A_nm : Array[i16[:]] = empty((n, m), dtype=int16)

We need to declare the variables m
, n
as constants. For example:
% cat examples/expr2.py
from lpython import i16, i32, Const
from numpy import empty, int16
def main():
n : Const[i32] = 15 # <~~~~~~~~~~~ LOOKS LIKE COMPILE-TIME CONSTANT ??? ~~~~~~~~~~
m : Const[i32] = 3
# Emulate getting stuff from the C side.
A_nm: i16[n, m] = empty((n, m), dtype=int16)
print(A_nm.size)
if __name__ == "__main__":
main()
% python examples/expr2.py
45
% lpython examples/expr2.py
45
Thanks! I'm leaving it open because of the uncaught exception, but your answer with Const
unblocks my work!
