a newbie to django and Cython. I am creating an app in django and need to import function in views.py from cythonized module. following is views.py inside my app.
from django.shortcuts import render
import sys
import numpy as np
import random
import math
from cython_node_val import node_val
def home(request):
return render(request,'Home.html',{"name":"user"})
def shortest_path1(request):
K=int(request.POST['number of layers'])
if ((K%2!=0) or (K < 0)):
return render(request,"shortest_path1.html",{'shortest_path1':"K must be an even integer"})
else:
......
Node_val=node_val(Hash,C,K) #node_val is from cython_node_val which is a .pyx file, Hash C and K
are defined in body after else statement.
sPath=np.zeros((K,3))
sPath[K-1,:]=Node_val[n-1,:]
for m in range(K-2,-1,-1):
sPath[m,:]=Node_val[int(sPath[m+1,1])]
return render(request,"shortest_path1.html",{'shortest_path1':sPath[:,3]})'''
the directory of my project is like following:
my app directory looks like this
cython_node_val.pyx works fine when importing into a normal .py file, but when doing the same inside views.py in my app it throws me following error
File "C:\Users\amit\projects\application_shortest_path\shortest_path\DS2P\urls.py", line 9, in <module>
from . import views
File "C:\Users\amit\projects\application_shortest_path\shortest_path\DS2P\views.py", line 6, in <module>
from cython_node_val import node_val
ModuleNotFoundError: No module named 'cython_node_val'
I believe if views.py is a python file and we can do operations, it should pull cython_node_val and associated functions. Where am i wrong?
Thanks for your time.

Use os.getcwd() to debug where you are running from your script views.py:
import os
print(os.getcwd())
ModuleNotFoundError: No module named 'cimport'
Then adjust the path to your needs
Is usually an error when you are trying to reference something that isn't in the python running path script + the path that you are giving inside your script.
