utils.box() vs. box()

[Christian Jakob]

Hi,

I removed all utils stuff from my scripts, now I got this error:

O.bodies.append(box(vec1,vec2,fixed=True,material=WallMat))
TypeError: box() takes at most 1 argument (4 given)

Is it a bug?

... it is working using utils.box() instead of box()

Hello Christian,
I was not able to reproduce your error.. Is it possible, taht you define
"box" function or variable in your script before this call? In case you
will not solve the problem, please attach a script, where the error is
reproducable.
Thanks
Jan

I was also not able to reproduce in a small example script.
I will given more informations, when I found the bug in my script.

Short time ago I had a similar problem with friction angle.
For better understanding I will explain my script handling. I prefer to use a MASTER file:

### MASTER.py ###

execfile('userinput.py')
execfile('scripts/definitions.py')
execfile('scripts/set-filenames.py')

execfile('scripts/0-generate.py')
execfile('scripts/1-replace.py')
...

######

### userinput.py ###

...
friction_coeff = 10
angle = atan(friction_coeff)
...

######

so angle should be a float number, right?

but loading a simulation (xyz.yade) via MASTER file and print angle gave:

print angle
<function angle at 0x2fdfb90>

but:

print atan(friction_coeff)
1.4711276743

I think this is related the the box issue:

print box
<function box at 0x4b2d758>

angle is float number as long as in other files ('scripts/definitions.py'
etc.) or 'userinput.py' itself angle is not a name of a function (as
probably is accodring to your output). With box it is the same case,
somewhere in your files (or possibly in some "from ... import *" or "from
... import box") must be defined 'angle' and 'box' function.

In Ipython, you can try

box?

it could give you some information

cheers

thanks jan for the hints.
i did not define "angle" or "box" in my scripts.

the problem was in importing pylab,
ipython gives:

In [1]: box
---------------------------------------------------------------------------
NameError Traceback (most recent call last)
<ipython-input-1-19a86833023e> in <module>()
----> 1 box

NameError: name 'box' is not defined

In [2]: angle
---------------------------------------------------------------------------
NameError Traceback (most recent call last)
<ipython-input-2-975bff1628dc> in <module>()
----> 1 angle

NameError: name 'angle' is not defined

In [3]: from pylab import *

In [4]: angle
Out[4]: <function numpy.lib.function_base.angle>

In [5]: box
Out[5]: <function matplotlib.pyplot.box>

solved.
