I am getting a similar issue to a post i found here

Python Data Function Temp File Not Found - Python Engine Version Change | TIBCO Community

Though I am running a more recent version of Spotfire and the solution dose not seem to apply to my situation.

Previously the post mentioned the following error being related to...

"It was due to an Input Parameter that had not been referenced in the script.

The file not found error occurs whenever there is a mismatch between the parameters defined in Edit Script and those used in Edit Parameters.

Checking required parameter is a handy safeguard for this." -John.lyall

I have went though the script and do not seem to find a mismatch.

Please let me know if you need any other informationon this. Thanks is advance for the support!

--------------Python Script ----------------

from Python_Data_Function import *

# Put package imports here

# Please make sure you have the correct packages installed in your Python environment

from sklearn import preprocessing

from sklearn.ensemble import IsolationForest

import pandas as pd

import numpy as np

#Analysis using IsolationForest

cols = ['ProdPerMinute', 'Pressure', 'BaroPressure',

'WasteGas', 'LossOfEfficiency', 'SR', 'PowerIn', '1dp', '2dp', '3dp',

'4dp', '5dp', '6dp']

train = it[cols]

scale = preprocessing.MinMaxScaler(feature_range=[0,1])

X_train = pd.DataFrame(scale.fit_transform(train),columns = train.columns)

clf = IsolationForest(n_estimators=nEstimators, max_samples=MaxSamples,contamination=Contamination, bootstrap=True)


it['Prediction'] = pd.DataFrame(clf.decision_function(X_train))

ot = it

--------------ERROR MESSAGE-----------

Could not execute function call 'PDF_IsolationForest'
