Test errors related to distributions

[jpeyhardi]

I have some tests errors

The commit is jpeyhardi/Core@3e19064 and the environment used for the build is described by environment.txt

Using the Sublime Text build system (Ctrl + Shift + B then choosing StatisKit), I have the following error message:

is due to passing an integer that is in fact a numpy.int64 instance instead of being an Python int instance.
This means than int the loop, you must add a line v=int(v)

[pfernique]

Once these changes made, you need to update the Python source code to Python 3 syntax (error with basestring and dictionary changed size during iteration).
To do so, type the following commands (you must be located in the repository root):

 2to3 -n -w src/py/statiskit -x next
 2to3 -n -w test

This kind of errors

TypeError: iter() returned non-iterator of type 'Iterator'

is due to a missing __next__ method in a class that should represent an iterator in Python 3.
The method was named next in Python 2.
