ImportError: cannot import name _iterable

Question

I installed package tethne-0.8 (successfully on Windows 10, which worked well (that is, I could import it). Then, I started fiddling around a little bit, uninstalling the package, installing an older version, uninstalling the older version, and finally re-installing tethne-0.8. I really regret doing so (I should have known!), because now, importing tethne throws the following error:

File "C:\Python27\lib\site-packages\tethne\classes\feature.py", line 8, in <module>
from tethne.utilities import _iterable
ImportError: cannot import name _iterable

Tethne-0.8 is said to have installed successfully and I've checked all dependencies, which are also okay. I've also looked into the feature.py file:

"""
Classes in this module provide structures for additional data about
:class:`.Paper`\s.
"""

from collections import Counter, defaultdict

from tethne.utilities import _iterable
try:    # Might as well use numpy if it is available.
    import numpy as np
    argsort = lambda l: list(np.argsort(l))
except ImportError:
    from tethne.utilities import argsort

...and the utilities.py file:

def _iterable(o):
    if hasattr(o, '__iter__'):
        return o
    else:
        return [o]

I have obviously tried googling the issue. It's driving me crazy and really hope someone has a tip!

I've edited my post. I'm sorry, I'm quite new to all this and really don't know how to go about it. — NynkeLys, Feb 21 '18 at 13:03
I'm a bit stumped. If you are using a `virtualenv` or `conda`, I might create a new environment with a fresh install. If not, I might start using one of the two aforementioned environment managers so you have more control over your environment. -- alternatively, if you are using python3, you could use `pip-autoremove somepackage -y` to remove the package plus dependencies and then re install the package you want. That may give you a fresh install — matisetorm, Feb 21 '18 at 13:19
`import tethne`, `print(tethne)`, `from tethne import utilities`, `print(utilities)`, to make sure that the modules that you are importing are the ones you *think* that you are importing. — CristiFati, Feb 21 '18 at 13:30
@CristiFati I can't run any of those commands, they all give me the same ImportError message :-( — NynkeLys, Feb 21 '18 at 13:34
@matisetorm I use Python 2.7 (on purpose) without an environment manager and have already tried uninstalling and re-installing the package, using pip uninstall tethne and pip install -U tethne (and tried pip install tethne as well) — NynkeLys, Feb 21 '18 at 13:35
No, they, don't, it's your original line that does. Place them before `import _iterable`. — CristiFati, Feb 21 '18 at 13:35
It says: "ImportError: cannot import name utilities" now @CristiFati — NynkeLys, Feb 21 '18 at 14:10
Then, replace the last 2 statements that I mentioned by `print(tethne.utilities)`. — CristiFati, Feb 21 '18 at 14:11
Damn it: "AttributeError: 'module' object has no attribute 'utilities'". Sorry, I can't move to chat yet, as my reputation is not high enough. Thanks a lot for your help @CristiFati — NynkeLys, Feb 21 '18 at 14:15
Does this tell you anything, @CristiFati? http://diging.github.io/tethne/tethne.html#module-tethne.utilities — NynkeLys, Feb 21 '18 at 14:38
https://github.com/diging/tethne/blob/python/tethne/utilities.py#L108 does have that. Most likely the version that you have doesn't. Check your file. — CristiFati, Feb 21 '18 at 15:51

@CristiFati my file had that as well, so that was not it. I found a solution (see my edit) THOUGH I'm not entirely sure why it now works! — NynkeLys, Feb 21 '18 at 15:57

I seem to have found one working solution: I added the following two lines of code in the feature.py file, before importing _iterable. Now, I can import tethne successfully.

from collections import Counter, defaultdict
from tethne.utilities import mean

ImportError: cannot import name _iterable
