Error after "from new import instancemethod" when importing scipy.stats

I am getting an exception from scipy whenever I try to import the nltk package. The command and the error looks like this:

>>> import nltk

IndentationError: expected an indented block

I executed this command in a terminal (ubuntu 16.04 LTS system). I did not find anything about this error and the indentation doesn't look wrong.

The SyntaxError is in your file new.py (I guess it's in your current working directory). Try to switch to a directory where no new.py file is present (or move the new.py file in another directory), then the internal scipy import should work without problems.

On the other hand you can just upgrade to scipy 0.19.x. They removed the import there and it should work without problems.

Note that it's always a bad idea to name python files like builtin-modules! That's a common source for exceptions or unexpected behaviour.
