The notebooks and code folder respectively contains the latest bug-fixed sample code used in the book chapters.
If you are familiar with git and have a git client installed on your machine, simply clone the repository to your own machine. However, it is up to you to install all the dependencies for the repository. The necessary Python libraries are detailed in the requirements.txt file. The other requirements are detailed in the Requirements section below.
A better way that also ensures that all dependencies are downloaded is using Docker.
Docker is a tool for creating a "containerized" version of software that is independent of the underlying operating system. The included Dockerfile is the recipe that creates an "image" of all the software you need to run the sample code for MTSW, including all of the dependencies. This software image runs within the container managed by the Docker client on your machine.
The authors recommend using Docker. You won't have to worry about which operating system you're using, whether Windows, MacOS, or some Linux variant. You also won't have to worry about installing anything beyond the Docker client.
Visit the Docker Hub and download the free community edition of Docker Desktop for your operating system.
NOTE that versions of Mac OS previous to Sierra 10.12 or versions of Microsoft Windows previous to 10 Professional or Enterprise 64-bit will require that you install the Docker Toolbox instead.
After installing Docker Desktop, run the Docker Desktop application. We will be accessing it from the command line. To make sure that it is installed correctly, type the following from the command line.
docker --version
This should display something like
Docker version 18.09.0, build 4d60db4
If so, congratulations, you've successfully installed Docker.
The Docker image of has been pre-built and is hosted on Docker Hub. To download this (~2GB) image, type the following command into your terminal:
docker pull mikhailklassen/mining-the-social-web-3rd-edition:latest
Next, let's tag the image to something a little shorter. Type the following command into the terminal:
docker tag mikhailklassen/mining-the-social-web-3rd-edition:latest mtsw3e:latest
The Docker image is build using the Dockerfile, which is a recipe that tells the Docker client how to build the image. From within the same directory as this repository's Dockerfile, type
docker build -t mtsw3e .
This will "tag" your image with the name mtsw3e. Building the image will take some time. The Docker client has to download a base image and then install all of the dependencies. You will only need to do this once, provided you don't delete the image from your computer.
Some users report the following error (noted on MacOS):
$ docker build -t mtsw3e .
ERRO[0000] failed to dial gRPC: unable to upgrade to h2c, received 502
context canceled
If this happens to you, disable the experimental features by unchecking the option in your Docker preferences.
Once you've built the image you should see it in your list of images:
$ docker image ls
REPOSITORY TAG IMAGE ID
mtsw3e latest 326387cea398
The last step is to run docker-compose, which will launch the container we just built and connect it to a MongoDB database running in a separate container, which is needed for some of the code examples
$ docker-compose up
The output will look something like this:
You will see the instruction on the screen to copy/paste the URL into your web browser's search bar. Copy and paste the version of this URL that points to 127.0.0.1, e.g.
http://127.0.0.1:8888/?token=9f568d96a24a950fb9525ee2746fcdd1c04e035122067be3
If you do this, you should see a Jupyter Notebook server running and a list of all the Jupyter Notebooks that are a part of this repository.
When you are down working with the sample code, shut down the container as follows: hit CTRL-C in the terminal window where your app is running to interrupt Docker. Next, type
docker-compose down
This performs a clean shutdown of any infrastructure set up by Docker and stops all running containers.
If you're not interested in any of the MongoDB examples in Chapter 9, you can run the MTSW3e container by itself without needing to use docker-compose. To do so, run the command from within the repository's root directory:
docker run --rm -p 8888:8888 -v "$PWD"/notebooks:/home/jovyan/notebooks mtsw3e:latest
If you just to run the sample code on your own machine outside of any Docker container, you will need to install all the requirements yourself.
Assuming you have Python 3.3+ installed, it is best practice to create a virtual environment:
python3 -m venv mtsw
This creates a folder called mtsw. Change into this directory and activate the virtual environment. On Mac OS or Linux:
cd mtsw
source bin/activate
Then use pip to install all requirements:
pip install -r requirements.txt
You will also need to install the Java Development Kit, which is required by boilerpipe.
Note: MongoDB is require to run the last TwitterReference.py You can obtain it at www.MongoDB.com
There are several ways in which you can contribute to the project. If you discover a bug in any of the code, the first thing to do is to create a new issue under the Issues tab of this repository. If you are a developer and would like to contribute a bug fix, please feel free to fork the repository and submit a pull request.
