Hi all,

I am a happy user of pySim - thanks a lot for the work on it. Unfortunately, I think something broke during recent updates that might have to do with software versions. 

I went through a full reinstall and have done all the software installations mentioned in the, but when I do:

$ ./ -p0                                       

I get:

Traceback (most recent call last):
  File "./", line 31, in <module>
    from pySim.ts_51_011 import EF, DF, EF_SST_map, EF_AD
  File "/home/gagarin/Data/pysim/pySim/", line 324, in <module>
    from construct import *
ModuleNotFoundError: No module named 'construct'

I tried:

$ sudo pip3 install construct                                            
Requirement already satisfied: construct in /usr/local/lib/python3.8/dist-packages (2.10.67)

But that did not solve the issue. 

Any pointers are very welcome.

All the best,
