Bad marshal data (invalid reference)

[marwacher]

Hi !

i am running your code on python 3.6 and when i was trying to run the example number one this error occurs:
Traceback (most recent call last):
File "C:\Users\Marwa\Desktop\pfe\implementation_dbn\deep-belief-nets-for-topic-modeling-master\serialization.py", line 16, in load
return m.load(file)
ValueError: bad marshal data (invalid reference)

and at the same time and in the same function serialization.py, i got this error:

File "C:\Users\Marwa\Desktop\pfe\implementation_dbn\deep-belief-nets-for-topic-modeling-master\serialization.py", line 21, in load
return p.load(open(path, 'rb'))
_pickle.UnpicklingError: unpickling stack underflow

i am wondering if the problem appears because i am running your code on python 3.6 .
Couldn't fix these issues so any help !!
