Hello,
I using the following code:
if (PyArray_TYPE(arr1) == NPY_DATETIME) {
// Ensure datetime64[ms]
auto tmp =
reinterpret_cast<PyArrayObject*>(PyObject_CallMethod(reinterpret_cast<PyObject*>(arr1),
"astype", "(s)", "datetime64[ms]"));
std::swap(arr1, tmp);
Py_XDECREF(tmp);
// Ensure integer
tmp =
reinterpret_cast<PyArrayObject*>(PyObject_CallMethod(reinterpret_cast<PyObject*>(arr1),
"astype", "(s)", "i8"));
std::swap(arr1, tmp);
Py_XDECREF(tmp);
tmp = reinterpret_cast<PyArrayObject*>(PyArray_FromArray(arr1,
PyArray_DescrFromType(NPY_INT64), NPY_ARRAY_IN_ARRAY));
std::swap(arr1, tmp);
Py_XDECREF(tmp);
}
First, if something is wrong with my code let me known. Then I wonder
if I can have a safe shortcut to avoid converting datetime64 to i8. I
guess the internal data of datetime64[ms] is i8 thus copying and
casting the array may be avoided.
Thanks by advance
Best regards.
