AttributeError: 'module' object has no attribute '__version__'
Do you have a module named lda.py or lda.pyc in the current directory?
If so, then your import statement is finding that module instead of the "real" lda module.
I have installed LDA plibrary (using pip)
I have a very simple test code (the next two rows)

import lda
print lda.datasets.load_reuters()

But i keep getting the error

AttributeError: 'module' object has no attribute 'datasets'

in fact i get that each time i access any attribute/function under lda!
