Error import fdpexpect in some files in the folder Firmware/tools/

[luisan00]

System Ubuntu 18.04 4.15.0-33-generic
Executing some python scripts in /Firmware/tools/ appears the next error:

Traceback (most recent call last): File "./show_regs.py", line 4, in <module> import serial, sys, optparse, time, fdpexpect ImportError: No module named fdpexpect
This error can be avoided changing:
import fdpexpect
by:
from pexpect import fdpexpect

Using the latest pexpect PIP package for python2.7, and using from pexpect import fdpexpect import, returns the following error for me.

Connecting (use ^] to exit)

AttributeError: 'fdspawn' object has no attribute 'interact' 

I can get things working by installing a pre 3.0 version of the package pip install "pexpect<3". The reality is that the python tools haven't been updated since 2012 and pexpect has been refactored a lot.
