Thanks Sameer. I confirmed on my side as well. I will try to understand the why part now. Much appreciated. On Mon, Apr 16, 2012 at 11:58 PM, Sameer Grover <sameer.grover.1@gmail.com>wrote:

Hi,
I am using f2py to pass a numpy array of type numpy.int8 to fortran. It seems like I am misunderstanding something because I just can't make it work.
Here is what I am doing.
PYTHON b=numpy.array(numpy.zeros(shape=(10,),dtype=numpy.int8),order='F') b[0]=1 b[2]=1 b[3]=1 b array([1, 0, 1, 1, 0, 0, 0, 0, 0, 0], dtype=int8)
FORTRAN subroutine print_bit_array(bits,n) use iso_fortran_env integer,intent(in)::n integer(kind=int8),intent(in),dimension(n)::bits print*,'bits = ',bits end subroutine print_bit_array
RESULT when calling fortran from python bits = 1 0 0 0 0 0 0 0 1 0
Any Ideas? thanks, John

It seems to work if "integer(kind=int8)" is replaced with "integer(8)" or "integer(1)". Don't know why, though.
