Error loading matplotlib python module in Spotfire Analyst

[Luke George]

I am trying to deploy python modules as an .spk file to Spotfire sever and then import those modules in Spotfire analyst (10.8) in Data Function Properties. Everyhting works fine when I create a.spk file without the matplotlib module (or any module that depends on matplotlib). When I add matplotlib to my requirements.txt file, the .spk creation works, and the server deployment works,but then when I try to load any module in Spotfire analyst (not just the matplotlib module specifically), I get the following error:

Could not execute function call 'Untitled'

Traceback (most recent call last):

Any idea why this is

- Make sure that you are updating Analyst as well (Install updates) after deploying packages on Spotfire Server.

- Can you try to use a different version of Matplotlib in your requirements.txt file

- If this still does not help, can you share your requirements.txt file

[Luke George]

I am updating Spotfire analyst when I deploy a new .spk. I've tried now with the previous version of matplotlib but it still didn't work. My requirements.txt looks like this:#### requirements.txt ####matplotlib != 3.2.1

plotly == 4.5.0

seaborn == 0.10.0

scipy == 1.4.1

sklearn == 0.0

pyrolite == 0.2.4

opencv-python == 4.2.0.32

Pillow == 7.0.0

Image == 1.5.28

boto3 == 1.11.17

statsmodels  == 0.10.1

scikit-image  == 0.16.2

PyWavelets == 1.0.3

First of all, I am not sure why you used != in your requirements.txt file for Matplotlib.

 

I created my requirements.txt as 

 

#### requirements.txt ####

matplotlib == 3.2.1

 

 

 

I created a .spk file and deployed it on the server. Later I updated my Analyst client and created a simple python data function with the code:

 

import matplotlib
x=matplotlib.__version__

 

 

 

I collected the 'x' in a document property and I am able to get the version as 3.2.1 in it.

I had matplotlib != 3.2.1 because you asked me to try a different version of matplotlib. When I did that, it installed the previous version 3.2.0. Previously I have also installed 3.2.1 with the same problem.
