JMP functions (neural network)

BathyAly — Wed, 21 Jun 2023 07:38:46 GMT

Hello everyone,

I exported a python code from JMP with a neural network function. I am trying to run the code on Spyder but there is a function called "jmp.mz" and I don't know how to replace it. I do not know what this function does.

Could anyone help me with this ? Thank you in advance for your time.

Have a nice day.

Alyson

I am not sure what you did. I used Big Class as an example. I modeled :weight with :age, :sex, and :height as inputs. I published the model to Formula Depot. I generated Python code. Here it is:

from __future__ import division
import jmp_score as jmp
from math import *
import numpy as np

I do not see the function you asked about.

the mz() function is defined in jmp_score.py which is imported in the first line of the score code.

import jmp_score as jmp

You can find jmp_score.py in:

Mac
/Library/Application Support/JMP/17/scoring/Python

Windows

C:\Program Files\SAS\JMPPRO\17\Scoring\Python
