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

Question

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

Answer 1

Just rename your file cloudant.py to something else.

Answer 2

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

Answer 3

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:

(py35) stefans-mbp:work stefan$ python
Python 3.5.3 |Anaconda 4.4.0 (x86_64)| (default, Mar  6 2017, 12:15:08) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.57)] on darwin

>>> from cloudant.client import Cloudant
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
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
Collecting cloudant
Using cached cloudant-2.7.0.tar.gz
Requirement already satisfied: requests<3.0.0,>=2.7.0 in

Now it works:
