Hello,
I'm extending C with python (which is opposite way of what people usually
do, extending python with C), I'm currently stuck in passing a C array to
python layer, could anyone plz advise?
I have a C buffer in my C code and want to pass it to a python function. In
the C code, I have:
npy_intp dims [2];
> dims[0] = 10;
> dims[1] = 20;
> import_array();
> npy_intp m=2;
> PyObject * py_dims = PyArray_SimpleNewFromData(1, &m, NPY_INT16 ,(void
> *)dims ); // I also tried NPY_INT
> PyObject_CallMethod(pInstance, method_name, "O", py_dims);
In the Python code, I want to just print that array:
def f(self, dims):
print ("np array:%d,%d"%(dims[0],dims[1]))
But it only prints the first number correctly, i.e., dims[0]. The second
number is always 0.
Best,
Jialin
