ImportError: No module named 'cloudant.client'; 'cloudant' is not a package

I use Python 3.5 and I have installed cloudant package by an execute command:
sudo -H pip3 install cloudant
I try to connect with python database. According to the documentation - https://console.bluemix.net/docs/services/Cloudant/getting-started.html#getting-started-with-cloudant. This code should works:
from cloudant.client import Cloudant
client = Cloudant("username", "password", url="https://user_name.cloudant.com")
client.connect()
client.disconnect()
When I run it I get an error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/tomek/Projects/stage-control/cloudant.py", line 1, in <module>
from cloudant.client import Cloudant
ImportError: No module named 'cloudant.client'; 'cloudant' is not a package

I suspect your problem may be that the pip used to install the module isn't the pip that your python is using:
If I do pip3 install cloudant I get the same problem as you:

>>> from cloudant.client import Cloudant
Traceback (most recent call last):

ImportError: No module named 'cloudant.client'
This is because of this:
(py35) stefans-mbp:work stefan$ which pip
//anaconda/envs/py35/bin/pip
(py35) stefans-mbp:work stefan$ which pip3
/usr/local/bin/pip3
The wrong pip3 was used to install the cloudant module. To remedy, ensure you use the pip in the virtual env you're using:
(py35) stefans-mbp:work stefan$ pip install cloudant

Just rename your file cloudant.py to something else.

Are you running locally or in an app on Bluemix? There must be something wrong with your install, because the code looks fine. This code runs for me:
from cloudant.client import Cloudant
from cloudant.document import Document
client = Cloudant("username", "pw", url="https://username.cloudant.com")
client.connect()
thedb = client["databasename"]
for document in thedb:
print(document)
client.disconnect()
If you're running on Bluemix, make sure you have a requirements.txt file to trigger library imports. See https://pip.readthedocs.io/en/1.1/requirements.html

Python version/import confusion

I'm trying to get this Python 2.7 code to work.
https://github.com/slanglab/phrasemachine
I've downloaded and unzipped the repo from github. Here's what happens when I try to run the code.

So, I need the nltk module. I have that installed here:
Sure enough, Python 2 doesn't know about nltk.

Pip tells me that nltk is already installed, but for 3.5.
$ sudo pip install -U nltk
Requirement already up-to-date: nltk in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/nltk-3.2.1-py3.5.egg
Update 10/10/16: I installed the 2.7 version of Python via brew, which give me the 2.7 pip.
$ /usr/local/bin/pip --version
pip 8.1.2 from /usr/local/lib/python2.7/site-packages (python 2.7)
Then I installed nltk with that pip:
$ sudo /usr/local/bin/pip install -U nltk

It says it installed nltk but the warnings are concerning. And, Python 2.7 still fails to import nltk.

Final update! I pointed Python 2.7 to the site packages directory where Homebrew installs stuff and I'm now good!
>>> import sys
>>> sys.path.append('/usr/local/lib/python2.7/site-packages')

Since you have two python distributions, you also need two versions of pip. Find out where your pip executables are with which -a pip, and install pip for your Python 2.7 distribution if necessary. Then tell the pip that goes with Python 2.7 (perhaps /usr/local/bin/pip) to install the nltk.
(Edit: Pip must be able to find the proper Python on its PATH. I hadn't thought to go into this.)

cassandra-driver: ImportError: No module named queue

I'm installing cassandra-driver with pip on OSX 10.11.
Straight out of pip, cassandra-driver gives this error:
traceback (most recent call last): File "syncS3ToCassandra.py", line 19, in <module>
from cassandra.cluster import Cluster File "cassandra/cluster.py", line 48, in init cassandra.cluster (cassandra/cluster.c:74747)
File "cassandra/connection.py", line 38, in init cassandra.connection (cassandra/connection.c:28007)
ImportError: No module named queue
I haven't tried building cassandra-driver from source but pip is the recommended method. Here's my code:
from cassandra.cluster import Cluster
from cassandra.policies import DCAwareRoundRobinPolicy
cluster = Cluster()
session = cluster.connect('foo')

I also meet this issue on my mbp. And there are some other problems that I can't uninstall six. I use easy_install to update version from 1.4.1 to 1.10.0 to fix it.
$sudo easy_install -U six
Hope it can help you.

From the source code, you need the package six to be installed and it should have a subpackage moves which contains a module queue.py:
38 from six.moves.queue import Queue, Empty
Can you try to reinstall six?
pip uninstall six
pip install six

Since cassandra-driver (version 3.4.1) is only available as .tar.gz package, you have to recompile it from the sources. This is what pip do.
I successfully install it on OSX 10.11.5 (it took at least one minute to compile).
I try this:

The last error is normal because I don't have the server.
EDIT: Installation in Python 3.5
I successfully installed and tested (as much as I can) this driver in Python 3.5.1 on OSX 10.11.5

I have created a virtualenv using base prefix '/Library/Frameworks/Python.framework/Versions/3.5'.

I solved this issue by updating my ~/.profile with:
export PATH=/usr/local/bin:/usr/local/sbin:$PATH
and installing python-2.7.11
$ brew install python
Then restarting my shell.

Why doesn't django-enumfield work as advertised in the manual?

Oops.
