This repository will contain the teaching material and other information associated with our scikit-learn tutorial.
Parts 1 to 12 make up the day 1 session, while parts 13 to 23 will be presented in the day 2 session.
The 2-part tutorial will be held on Friday and Saturday, 5-6 May, 2017.
- Parts 1 to 12: 9:00 AM - 3:00 PM
- Parts 13 to 23: 9:00 AM - 3:00 PM
If you have a GitHub account, it is probably most convenient if you fork the GitHub repository. If you don’t have an GitHub account, you can download the repository as a .zip file by heading over to the GitHub repository (https://github.com/rhiever/webstep-sklearn-quickstart) in your browser and click the green “Download” button in the upper right.
Please note that I may add and improve the material until shortly before the tutorial session, and I recommend that you update your copy of the materials one day before the tutorials. If you have an GitHub account and forked/cloned the repository via GitHub, you can sync your existing fork with via the following commands:
git remote add upstream https://github.com/rhiever/webstep-sklearn-quickstart.git
git fetch upstream
git checkout master merge upstream/master
If you don’t have a GitHub account, you may have to re-download the .zip archive from GitHub.
This tutorial will require recent installations of
The last one is important, and you should be able to type:
jupyter notebook
in your terminal window and see the notebook panel load in your web browser. Try opening and running a notebook from the material to see check that it works.
For users who do not yet have these packages installed, a relatively painless way to install all the requirements is to use a Python distribution such as Anaconda, which includes the most relevant Python packages for science, math, engineering, and data analysis; Anaconda can be downloaded and installed for free including commercial use and redistribution.
The code examples in this tutorial should be compatible with Python 2.7, 3.4, 3.5, and 3.6.
After obtaining the material, we strongly recommend that you open and execute the Jupyter Notebook
check_env.ipynb that is located at the top level of this repository. You can open the notebook
by executing
jupyter notebook check_env.ipynbinside this repository. Inside the notebook, you can run the code cell by clicking on the "Run Cells" button as illustrated in the figure below:
Finally, if your environment satisfies the requirements for the tutorials, the executed code cell will produce an output message similar to the one shown below:
Although not required, we also recommend that you update the required Python packages to their latest versions to ensure best compatibility with the teaching material. Please upgrade already installed packages by executing
conda update [package-name]- or
pip install [package-name] --upgrade
The data for this tutorial is not included in the repository. We will be using several data sets during the tutorial: most are built-in to scikit-learn, which includes code that automatically downloads and caches these data.
Because the wireless network connections can often be spotty,
it would be a good idea to download these
data sets before arriving at the workshop.
Please run python fetch_data.py to download all necessary data beforehand.
The download size of the data files are approx. 280 MB, and after fetch_data.py
extracted the data on your disk, the ./notebook/dataset folder will take 480 MB
of your local solid state or hard drive.
