A little word cloud generator in Python. Read more about it on the blog post or the website. The code is Python 2, but Python 3 compatible.

Fast install:

pip install wordcloud

If you are using conda, it might be even easier to use anaconda cloud:

conda install -c https://conda.anaconda.org/amueller wordcloud

For a manual install get this package:

wget https://github.com/amueller/word_cloud/archive/master.zip
unzip master.zip
rm master.zip
cd word_cloud-master

Install the package:

python setup.py install

worcloud depends on numpy>=1.5.1, pillow and matplotlib. To install it via pip, you will also need a C compiler.

If you're having trouble with pip installation on windows, you can find a .whl file at:

If the installation of the package fails, due to a missing pyconfig.h file, you need to install the python-dev package.

For Python 2.*

sudo apt-get install python-dev

For Python 3.*

sudo apt-get install python3-dev

If the compilation via gcc of the package fails, due to a missing Python.h file, you need to install the python-devel package.

For Python 2.*

sudo yum install -y python-devel

For Python 3.*

sudo yum install -y python34-devel

The wordcloud_cli.py tool can be used to generate word clouds directly from the command-line:

$ wordcloud_cli.py --text mytext.txt --imagefile wordcloud.png

If you're dealing with PDF files, then pdftotext, included by default with many Linux distribution, comes in handy:

$ pdftotext mydocument.pdf - | wordcloud_cli.py --imagefile wordcloud.png

In the previous example, the - argument orders pdftotext to write the resulting text to stdout, which is then piped to the stdin of wordcloud_cli.py.

Use wordcloud_cli.py --help so see all available options.
