Run Cisco Webex on 64-bit Fedora 28/CentOS 7

With Audio and Screen Sharing Enabled

IMPORTANT NOTE :

1. The Screen Sharing works when you use Xorg instead of Wayland.
2. In my test, I disabled SELinux but maybe it works even if SElinux is permissive.
3. This was tested and worked on the DELL VOSTRO 3560 but does not work on DELL PRECISION 7510

Basic Usage

Example of training an HDBSCAN model using the hdbscan Python package in Scikit-learn contrib:

from sklearn import datasets
from hdbscan import HDBSCAN

X = datasets.make_moons(n_samples=50, noise=0.05)

model = HDBSCAN(min_samples=5)

Comparing cuML K-Means API Against Scikit-learn & Dask-ML

First, a quick code example of K-Means in Scikit-learn

from sklearn.datasets import make_blobs
from sklearn.cluster import KMeans

n_centers = 5

X, _ = make_blobs(n_samples=10000, n_centers=n_centers)
