Suppose I have
a = np.zeros(2, dtype=[('a', np.int), ('b', np.float, 2)])
a[0] = (2,[3,4])
a[1] = (6,[7,8])
then I define the same Cython structure
import numpy as np
cimport numpy as np
cdef packed struct mystruct:
np.int_t a
np.float_t b[2]
def test_mystruct(mystruct[:] x):
cdef:
int k
mystruct y
for k in range(2):
y = x[k]
print y.a
print y.b[0]
print y.b[1]
after this, I run
test_mystruct(a)
and I got error:
ValueError Traceback (most recent call last)
<ipython-input-231-df126299aef1> in <module>()
----> 1 test_mystruct(a)

ValueError: Expected 1 dimension(s), got 1
My question is how to fix it? Thank you.
