Hello. I have a file anyModule.py which I import with the line "import anyModule" from my YADE script bouncingSphereForum.py, but the following error appears: "ImportError: No module named anyModule". If I place the code of the module inside the YADE script it gives no error. Could anyone tell me how to import python modules from within YADE? Thank you very much. The scripts are the following:


YADE script: 


import numpy as np
import anyModule

# basic simulation showing sphere falling ball gravity,
# bouncing against another sphere representing the support
# DATA COMPONENTS
# add 2 particles to the simulation
# they the default material (utils.defaultMat)
O.bodies.append([
# fixed: particle's position in space will not change (support)
utils.sphere(center=(0,0,0),radius=.5,fixed=True),
# this particles is free, subject to dynamics
utils.sphere((0,0,2),.5)
])


# Prints in file the center coordinates of the bouncing sphere
#def printFile():
    #h = [O.bodies[1].state.pos[2]]
    #np.savetxt("height" + str(O.iter) + ".txt", h)

# FUNCTIONAL COMPONENTS
# simulation loop -- see presentation for the explanation
O.engines=[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb()]),
InteractionLoop(
[Ig2_Sphere_Sphere_L3Geom()],
 # collision geometry
[Ip2_FrictMat_FrictMat_FrictPhys()], # collision "physics"
[Law2_L3Geom_FrictPhys_ElPerfPl()]
 # contact law -- apply forces
),

# damping: numerical dissipation of energy
NewtonIntegrator(damping=0.1, gravity=(0,0,-9.81)),
PyRunner(command = "anyModule.printFile()", iterPeriod = 500000)
]
# set timestep to a fraction of the critical timestep
# the fraction is very small, so that the simulation is not too fast
# and the motion can be observed
O.dt=.5e-4*utils.PWaveTimeStep()
# save the simulation, so that it can be reloaded later, for experimentation
O.saveTmp()

#print "it was here"

O.run(2000000)

*****************************************************************

Python module:

# Prints in file the center coordinates of the bouncing sphere
def printFile():
    #h = [O.bodies[1].state.pos[2]]
    #np.savetxt("height" + str(O.iter) + ".txt", h)
