Sorry for that. Below is my MWE.
1. the initial particles set saved by
sp = pack.SpherePack()
sp.save('initial_spheres-before_translation-x.txt')
Find file here,
https://drive.google.com/file/d/1VIYd7qzb5b4iIAyldT49I1Fjko8XxjhI/view?usp=sharing
2. the python script to translate those particles in x direction,
import numpy as np
data = np.loadtxt('initial_spheres-before-translation-x.txt',
delimiter=' ', skiprows=0)
with open('initial_spheres_translate_x.txt','w') as fd:
for i in range(len(data)):
fd.write('%.9f %.9f %.9f %.5e %d\n' % (data[i,0]+0.5e-3,
data[i,1], data[i,2], data[i,3], -1))
Find file here,

3. The yade code to load the translated particles,
from yade import pack,geom,utils
sp = pack.SpherePack()
sp.load('initial_spheres_translate_x.txt')
### the initial particles before translation can be loaded ###
#sp.load('initial_spheres-before-translation-x.txt')
print('load initial_spheres')
sp.toSimulation()
Thanks.
