X13ARIMA & statsmodels: X13NotFoundError: x12a and x13as not found on path

[JaneTan]

I am on Window OS. I downloaded the Windows version of X13 software from https://www.census.gov/data/software/x13...-635278563.

I would like to use it with my Python code as below.
But I get error:
X13NotFoundError: x12a and x13as not found on path. Give the path, put them on PATH, or set the X12PATH or X13PATH environmental variable.

import pandas as pd
from pandas import Timestamp

s = pd.Series(
    {Timestamp('2013-03-01 00:00:00'): 838.2,
 Timestamp('2013-04-01 00:00:00'): 865.17,
 Timestamp('2013-05-01 00:00:00'): 763.0})
     
     
import os
os.chdir(r'C:\Users\user-name\Downloads\x13as_ascii-v1-1-b59\x13as')

import statsmodels.api as sm
sm.tsa.x13_arima_analysis(s)

OK, so what is your question? Is it about setting environment variables? If so, that's a Windows question, rather than a Python one. If you want to specify the path to the executable, then you'll need to consult the documentation for the library to see how it lets you do that.
