BackRead method missing in madgraph.various.misc (272py3)

[Wolfgang Waltenberger]

Hey Olivier, all,

when upgrading from 265py2 to 272py3, my setup crashes, with the error given below.
Do you have any idea what this could be about? It is true, I dont see any "BackRead" methods
in misc modules (neither in the "internal misc" module).
Thanks a lot in advance,

Wolfgang

Hi,

Python3 is so difficult with file handling (so bad since it was a key feature of python2).
That I will need to look at this in details how to put back such type of support.

Using the non python3 version is the work around for the moment.

Cheers,

Olivier

Here is a first attempt to fix the issue.
