error with kmos view command

[Abel-Ding]

Expected behavior

run thekMC model about CO adsorption and desorption according to the tutorials: A first kMC Model- the API way (http://kmos.readthedocs.io/en/latest/tutorials/index.html)

Actual behavior

I installed the kmos and the dependencies on ubuntu 16.04, and learn the tutorials "A first kMC Model-the API way"

while, after I export the xml, and try to view the model, it rised an TypeError, the error info is shown as followed:

    View.__init__(self, self.vbox, rotations)
TypeError: __init__() takes exactly 2 arguments (3 given)

It seems to be related to the ase.view, but I don't know how to deal with it.
How could I fix this problem? Did I do something wrong in installation?
Looking forward to your solution and suggestion.

I took a quick look and it looks like somewhere between ase version 3.12.0b1 (the one I happen to have in my workstation) and the current version, they changed the signature for ase.gui.view.View from

def __init__(self, vbox, rotations):
to
def __init__(self, rotations):

Sadly, I am not familiar with how this class works on ase and/or the significance of the vbox parameter for kmos. If you need to use the viewer as soon as possible, I would recommend reverting to and older ase version for now.

An alternative quick hack that could work, but is definitely not guarranteed to is to change
View.__init__(self, self.vbox, rotations)
to
View.__init__(self, rotations).
If you test this and works, you could then wrap this line in a try-except block, that calls the function without the vbox arguments in case of an exception.

However, I doubt this will work. I guess @mhoffman should be able to come up with an estimate on how difficult implementing support for this newer ase version would be.

Hope this helps,
Juan
