[Pkg-electronics-devel] Bug#1032392: python3-scikit-rf: import fails: AttributeError: module 'collections' has no attribute 'Sequence'

[Josef Schneider]

Hello,

I have attached a debdiff where I import the collections.abc python 
package which has the Sequence and MutableMapping attributes instead of 
collections. This patch is applied to the 0.15.4 upstream which is the 
current in debian. With this fix, the package builds and importing the 
skrf package in a python console works as expected. I can upload this RC 
bug fix as a NMU if you want. Thanks!
