Start by disabling browser extensions, particularly ad blockers, as they sometimes interfere with the video player. If the problem persists, try Chrome or Firefox in a private window. Persistent buffering is usually a network issue — a wired connection or switching from mobile data often resolves it.
Yes. Each lesson that includes code or sample datasets has a download button below the video player. Files are in .zip format and include a short readme explaining the expected environment setup.
Access is retained for 12 months from the date of purchase. If a course is substantially updated within that period, the updated materials are included at no additional cost.
Submission errors are usually caused by a session timeout. Refresh the page, log in again, and try submitting once more. If the error recurs on the same exercise, note which lesson and exercise number it affects and email that detail to [email protected].
Before you write to us
These steps solve the majority of reported issues without waiting for a reply.
Clear cache and cookies
Stale session data causes most login and display glitches. Clearing cache in your browser settings takes under a minute and resolves roughly two-thirds of platform complaints.
Check your Python environment
Course notebooks are tested on Python 3.10 with the library versions listed in requirements.txt. Version mismatches between pandas, scikit-learn, or numpy account for most code-related errors.
Try a different browser
The platform is tested on Chrome 120+, Firefox 121+, and Safari 17+. Older versions or Chromium-based browsers with aggressive security policies occasionally block required scripts.
Review the lesson prerequisites
Several modules on feature engineering and model evaluation assume familiarity with linear algebra and basic statistics. The prerequisites are listed at the top of each module page.
