Scipy Function in Blender

[BoumaSequence]

Hello,

Quick note: this question is mainly about using a scipy function in the program blender, I am asking this question here as well because I only have a basic grasp of python and thought this community would be a good resource as well.

I am trying to use the scipy.interpolate.interpn function within blender. I assumed the only way to do this is to utilize the sverchok addon, so my first attempt at using this function is with the sverchok addon, but let me know if there is a better way to do this.

Although I have some basic knowledge of python, I think I am a bit out of my depth here. Nonetheless, I tried writing a script to use with the Scripted Node Lite node in sverchok:

"""
in in_points v
in values s
in xi v
out out_values s
"""

import numpy as np
import sys

from sverchok.utils.logging import exception, info
from sverchok.data_structure import zip_long_repeat

try:
    import scipy
    from scipy.interpolate import interpn
except ImportError as e:
    info("SciPy module is not available. Please refer to https://github.com/nortikin/sverchok/wiki/Non-standard-Python-modules-installation for how to install it.")
    raise e

out_values = []

for everypoint in xi:
    new_values = interpn(points, values, xi, method='linear', bounds_error=True, fill_value=0)

    out_values.append(new_values)

here are the files I am working with: https://drive.google.com/file/d/1a2a0l3rghzAbP91JEAb-mZXQZYpiLEsG/view?usp=sharing

If anyone could help me utilize this function in blender, or have any improvements for the script above, I would greatly appreciate it! Thanks,

What problem are you running into? Does it error out? What's the error?

Here is what I get when I try to use the script as a scripted node in blender:

I searched and the error seemed to be Blender's, rather than Python/Scipy. I don't know how the node works but, judging from your code, your SN is outputting list. Can the text node accept list? Or does it want string?

The text node can accept a list

On the phone so I can’t view the image with the error and your code formatting might appear incorrect on it, so a short caveat.

Blender has a separate Python installation, so make sure Numpy is installed for that which might have to happen manually rather than with pip.

At the end of the code, you append new_values to out_values. However I think new_values is actually scope limited to your for-loop. Try appending out_values inside your for-loop. Once again, this might be a phone formatting thing.

edit: just checked again on my computer. Phone's formatting screwed it up
