Description changed to:
Hi everyone,

I am using Ubuntu 18.04, and Yade 2019-08-08.git-775ae74
I use the Triaxial code by Bruno Chareyre [1] 
[1] https://gitlab.com/yade-dev/trunk/blob/master/examples/triax-tutorial/script-session1.py

My goal is to get micro variables from Triaxial test and save them in a
text file for the whole specimen (for all contacts). To do so, I just
added the following codes at the end of [1] and made no changes:

# the fabric tensor
utils.fabricTensor()

# inter-particle forces
for i in O.interactions:
   fn = i.phys.normalForce
   fs = i.phys.shearForce

# branch vectors, and contact normals
for i in O.interactions:
   normal = i.geom.normal
   b1,b2 = [O.bodies[id] for id in (i.id1,i.id2)]
   p1,p2 = [b.state.pos for b in (b1,b2)]
   branch = p2 - p1
# Save Data
from pprint import pprint
plot.reset()
plot.addData(fn,fs,normal,brach)
pprint(plot.data)
plot.saveDataTxt('/tmp/MicrodataFile.txt.tar.gz',vars=('fn','fs','normal','branch'))

And the output I get is as follows:
