I constructed an numpy array::
a=np.ndarray([2,3])
then i want to see where its data are::
a.data
>>>Out[213]: <read-write buffer for 0x0482C1D0, size 48, offset 0 at 0x049E87A0>
a.data
>>>Out[214]: <read-write buffer for 0x0482C1D0, size 48, offset 0 at 0x049E82A0>
a.data
>>>Out[215]: <read-write buffer for 0x0482C1D0, size 48, offset 0 at 0x049E81C0>
...
why every time the offset address is different?
if i want to transfer the data to a c function using c_types by::
ctypes_array = (ctypes.c_char * a.size * 8).from_address(ptr)
how should i get the value of ptr?
