I tried to compile a single file my_wiggle_falloff.pyx based on wiggle_falloff.pyx, and it pops up an error relative cimport beyong main package is not allowed. Below is the setup.py. Is it possible to compile a single file rather than the whole package?

You probably need to set the include dir to the Animation Nodes header and import using a path relative to the Animation Nodes module.
See the Cython section of the developer guide for extensions:

Thanks Omar！Will try!
Hi Omar,
I was not able to complie correctly, please take a look and many thanks.

Can you provide a more complete version of what you are trying to do so that I can test it locally?
It is unclear to me why you import animation_nodes in the setup file here.

setup.py is as below:
from setuptools import setup, Extension
from Cython.Build import cythonize
from Cython.Distutils import build_ext
extensions = [
Extension(
"my_wiggle_falloff",["my_wiggle_falloff.pyx"],
"include_dirs", ["C:/Users/UPC/Documents/Downloads/animation_nodes_headers"],
),
]
setup(name='my_wiggle_falloff',
ext_modules=cythonize(extensions),
)my_wiggle_off.pyx is below:
import bpy
from bpy.props import *
from ... base_types import AnimationNode
from ... data_structures cimport BaseFalloff
from ... algorithms.perlin_noise cimport perlinNoise1D
class WiggleFalloffNode():
def execute(self, seed, evolution, speed, offset, amplitude, octaves, persistance):
evolution *= max(speed, 0) / 10
return WiggleFalloff(seed, evolution, offset, amplitude, octaves, persistance)
cdef class WiggleFalloff(BaseFalloff):
cdef:
double evolution
double offset, amplitude
double persistance
int octaves
def __cinit__(self, float seed, float evolution,
float offset, float amplitude,
int octaves, float persistance):
self.evolution = seed * 341312 + evolution
self.amplitude = amplitude
self.persistance = persistance
self.offset = offset
self.octaves = min(max(octaves, 0), 100)
self.clamped = False
self.dataType = "NONE"
cdef float evaluate(self, void *object, Py_ssize_t index):
cdef double x = self.evolution + index * 1127
cdef double noise = perlinNoise1D(x, self.persistance, self.octaves)
return <float>(self.amplitude * noise + self.offset)You should probably set the include path in the cythonize function as follows:
from Cython.Build import cythonize
from Cython.Distutils import build_ext
from setuptools import setup, Extension
extensions = [
Extension(
"my_wiggle_falloff", ["my_wiggle_falloff.pyx"]
),
]
setup(
name = "my_wiggle_falloff",
ext_modules = cythonize(extensions,
include_path = ["/path/to/animation_nodes_headers", "."],
compiler_directives = {"language_level" : "3"}),
)And use absolute imports relative to the animation_nodes module as follows:
from animation_nodes.data_structures cimport BaseFalloff
from animation_nodes.algorithms.perlin_noise cimport perlinNoise1Danimation_nodes.
It worked well now. Thanks a lot Omar! Your supports are always great!
Hi Omar, although the compilation is ok, when call my_wiggle_falloff, it will generate below errors:animation_nodes.data_structures.meshes,mesh_data.Mesh size changed ,may indicate binary incompatibility, expect 88 from c header, got 80 from pyobject. not sure why?
This likely means that your headers are older/newer than your compiled files. Make sure both the headers and the compiled objects are of the same version.

Thanks Omar again.
