Details
Trying to copy a .NET array to a numpy array using Marshal as in the example on themailing list:
import clrfrom System import Array, Double, IntPtr, Randomfrom System.Runtime.InteropServices import Marshalimport numpy as npr = Random()src = Array.CreateInstance(Double, 10000000)for i in xrange(len(src)): src[i] = r.NextDouble()from System.Runtime.InteropServices import Marshaldest = np.empty(len(src))dest_ptr = IntPtr.__overloads__[int](dest.__array_interface__['data'][0])Marshal.Copy(src, 0, dest_ptr, len(src))was working fine in python 2 but in 3 results in
Traceback (most recent call last): File "test.py", line 12, in <module> dest_ptr = IntPtr.__overloads__[int](dest.__array_interface__['data'][0])TypeError: no constructor matches given argumentsTODO
How can the changedpython 3 int be used in this constructor?
