error when run python code(created through JMP formula depot )

JMP model would give me a formula and I want pass the formula and used it in python or R program.

Through formula depot, it generated Python code, and I tried to copy the python code and run it through Jupiter Notebook, but always give me error :

for example, I attached the test file and python code created from JMP and run. it didn't recognize  as array... please help. thanks!!! I thought it is easy to copy JMP created python code and run python with no problem. looks it is not.....

 

def score(indata, outdata):
_temp_0 = u""

if (indata[u"Num"] > 50):
_temp_0 = u"High"
else:
_temp_0 = u"Low"
outdata[u"class"] = _temp_0

return outdata[u"class"]

 

 

 890         raise ValueError("The truth value of a {0} is ambiguous. "
    891                          "Use a.empty, a.bool(), a.item(), a.any() or a.all()."
--> 892                          .format(self.__class__.__name__))    893 

 

the following is python code from JMP

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

return outdata[u"class"]

 

the data is looks like

Num Class

15 Low
17 Low
200 High
60 High
72 High
10 Low
20 Low
70 High
55 High
20 Low
854 High

Re: error when run python code(created through JMP formula depot )

Hi Lucy,

The short answer is that you have to use a data structure to hold your data that is compatible with the code generated by JMP. It expects the input and output arguments to be of a dictionary-like type, where values can be accessed and written by key. The ideal data structure to use for a table is a Pandas DataFrame. Here is how you would add a new column to a DataFrame using the JMP score function from your example:

 

 

import pandas as pd

indata_df = pd.read_table(testdata, sep = ',') indata_df['predicted_class'] = indata_df.apply(lambda s: score(s, {}), axis=1)

Please see the attached files for a complete example. Also, please take a look at the example code attached to the Discovery presentations where the Formula Depot code generation was covered, Scoring Outside the Box and Sharing the Ultimate Boon.

 

 

Re: error when run python code(created through JMP formula depot )

Glad you find it helpful! I would suggest that you do not copy and paste the JMP code into the notebook - that only works for very small models and the two you mentioned can be quite large. Instead, just import the generated file as in the Discovery notebook examples I mentioned. 

 

Here is a tip: start your notebook in the same directory you saved the JMP-generated python code, as well as a copy of the helper file jmp_score.py file that comes with the product, so that Python can find them more easily. See this discussion for more details.

Nasif,

 

Thank you so much for your knowledgable and quick reply.  It works very well for this. I will try more complicated python code created by JMP (Boosted tree/Random Forest formula, although looks like take long time even copy and paste jupyter notebook)

yeah, it is really a good suggestion!!! I am not good at python since I have been writing SAS codes for 20 years.

Nasif, 

 

one more question, in the newer version, Formular Depot will generate R code? thanks!

Re: error when run python code(created through JMP formula depot )

Hi again,

 

We have had requests for R language code generation but unfortunately, it is not on the product or on the roadmap yet.

I would suggest adding an entry to the JMP Wish List so that we can track the general interest in this feature.

Re: error when run python code(created through JMP formula depot )

that would be good if JMP could add R code. especially our industry use Spotfire and R codes will be easily embeded with Spotfire. 

Thanks!

Re: error when run python code(created through JMP formula depot )

I don't have access to Spotfire so it is not possible for me to try it, but apparently, it is possible to run Python code in SpotFire too.

Please take a look at these links, they might help:

Nascif, https://community.jmp.com/t5/Discovery-Summit-2016/Scoring-Outside-the-Box/ta-p/22381 the example in this presentation really help me a lot. Great presentation and thank you so much for sharing the example and code.
