sudachipy/lattice.pyx:35:12: Assignment to const attribute 'connect_costs'
Hi, After building the latest codes from git (branch "develop"), I have the following issue:
$ python setup.py build_ext --inplace
running build_ext
skipping 'sudachipy/latticenode.c' Cython extension (up-to-date)

self.end_lists.append([bos_node])

Can you show me how to tackle the above issue, please? Thanks advance for your help.
Then, I updated our file "./sudachipy/lattice.pxd" (remove "const" in line "cdef const short[:,:] connect_costs") as follows
from .latticenode cimport LatticeNode
cdef extern from "limits.h":
cdef int INT_MAX
cdef class Lattice:
cdef int size
cdef int capacity
cdef LatticeNode eos_node
cdef list end_lists
cdef object grammar
cdef object eos_params
# cdef const short[:,:] connect_costs
cdef short[:,:] connect_costs
cpdef void resize(self, int size)
cpdef void insert(self, int begin, int end, LatticeNode node)
cdef void connect_node(self, LatticeNode r_node)
cdef void connect_eos_node(self)
Then, building is okie as follows:
