Lightstreamer in Anaconda Python Distribution

[Kantor_Lek]

Hello all,

I've been just starting to try to use the Lightstreamer client in Python 3.9 in the Spyder IDE, and I get an error on import.

The only line of code I run is:

from lightstreamer_client import *

and I get the following output:

Traceback (most recent call last):
