Python Data Function Temp File Not Found - Python Engine Version Change

[John Lyall]

Modulesimported and script has runfine previously with Pandas etc, PyDf has now stopped working.Environment variables are all set up set up.

It is possible my Python Engine has changed, i noticed before it was 3.4 and running fine, now it is 3.7.4and there is no option to revert it.

Error Message:

Could not execute function call 'outputcheck'

File not found: C:Usersw55207AppDataLocalTemptmpDD7D.stdf

Example Script:

from Python_Data_Function import *

# Put package imports here

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

# Attempting to output to document propertynamed dataout2

dataout2 = 'madeit'

Solved:

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.

 

Note this is forSpotfire 10.3

There seems to be no issue with the Python Engine Version Change.

UPDATE: as of Spotfire 10.7, Python for data functions is now native in Spotfire. Users on Spotfire 10.7+ should use the native version which you can read about here: https://community.spotfire.com/wiki/Python-data-function-tibco-spotfire"
