Frequently Asked Questions

Which course should I take first?

All of our courses are designed to stand alone; there is no sequence in which you must take them. If you’re getting started in machine learning, Machine Learning, Data Science and Deep Learning with Python is a good place to start. If you’re more interested in big data, you might start with The Ultimate Hands-On Hadoop: Tame your Big Data.

If you’re interested in AWS certification, we offer both video courses and practice exams for the Data Analytics and Machine Learning Specialty exams. You’ll probably want the practice exams after taking the associated course.

Which Spark course should I take?

First, decide if you’re more comfortable with the Python or Scala programming language. There are two introductory courses that are similar, but one uses Python, and the other uses Scala. Spark works better with Scala.

The Python-based course is Taming Big Data with Apache Spark and Python, and the Scala-based course is Apache Spark 3 with Scala.

Once you’ve completed one of those courses, you may want to dive deeper with Spark Streaming by taking Streaming Big Data with Spark Streaming, Scala, and Spark 3.

Where do I get the course materials from?

Generally one of the first video lectures in the course you have purchased will walk you through how to set up the software you need, and how to obtain the code associated with the course.

How can I get my questions about the course answered?

Just post a comment on the lecture you have a question about, and we’ll see it! You might also check out the “community” menu for a place where you can talk with your fellow students.

Please keep in mind we can only answer questions about the course itself. We can’t offer free advice and consulting on your projects outside of the course.

I’m having a problem with the site; how can I let you know?

Send an email to and we’ll look into it right away!

What is your refund policy?

All sales are final, as stated in our terms of service. We encourage you to check out the free lectures on each course, and our free trial course on deep learning to make sure our platform and teaching style works for you before you purchase. Subscriptions of course may be cancelled at any time.

How do I cancel my membership plan?

If you’ve finished your learning with us, just log into your account from our home page or use the “My Courses / Log In” menu option on our site. From there, select “My Subscriptions,” and you may cancel your membership there.

    Hello Sundog education ,

    I’m George and I am an entrepreneur in the online education business.
    My team and I are working on creating an education platform for teachers like yourself and we are wondering how you feel about udemy and if there is something you are missing when teaching using their platform.

    Any insight would be greatly appreciated and help us a ton

    Thank you for your time

      I can’t say I have any big pain points with Udemy from a feature perspective. My only gripe is the low revenue per enrollment instructors end up with there. They make up for it with volume, but it means you have a lot of students to take care of. Otherwise they’re actually good to work with on the whole. On a higher level, the biggest problem facing online instructors right now is all the competition around the world – a LOT of people decided to become online instructors during the pandemic, and it’s very hard for new courses to find an audience as a result. Best of luck with your venture!

    I am working on making subtitles for your courses on Udemy, and I’m really sorry to tell you this but the video clips of your lecture allowed to me is of low quality and I can barely read the codes (This is only the case for Boltzmann section). So would you mind if I ask you to open up the course for me for some time? A few days would be just fine. Thanks.

      I mean RBM section.

      Hi, I’ll email you a coupon code you can use right now.

    Hi Frank,

    I wanted to understand what is the difference between courses on Udemy and Sundog websites.
    Ex. Machine Learning, Data Science and Deep Learning with Python Course

    There is a price difference on both the platform, Udemy is very cheap compared to Sundog eduction. What additional I will get if I subscribe to Sundog Education.

    I want to get into ML field and need right support to achieve it.


    1. Z S says:

      Also, let me know if there are any coupons available for discounts.

    2. Frank Kane says:

      Sounds like Udemy is running a sale! By purchasing here you will get direct support from the instructor (me) rather than a TA on Udemy, plus your money goes to the instructor instead of to Udemy.

      I’m thinking of running a sale on this site soon as well, but if you’d rather purchase at Udemy, please use this referral link at least: – that way we’ll end up with more than a dollar from your enrollment.

    Have a big problem.. Anaconda3 won’t install. I get the “Failed to create menus” error.
    Evidently this has been a Anaconda problem for a long time, many of the help sites go back to 2016.
    Hoping you have a suggestion so I can get started on the course. Got 60% finished on one of your Udemy courses.
    Made a dozen different attempts to get past the error.
    * I had already deleted my old Anaconda.
    * From CMD zapped out the $Path and reran
    * Tried running as administrator and toggling the Add Path and Install All variables.
    * Downloaded an earlier version and the 32bit version, both failed with the same.
    I can’t post my screen captures but it seems like Anaconda can’t find its own directories it just created in the install.

    Hoping you can give some guidance or provide some links so I can get going.

    1. Frank Kane says:

      I’ve never encountered that myself, so all I can do is point you to the same webpages for troubleshooting that it sounds like you’ve already found (I’d just Google “Anaconda failed to create menus”). I searched all of the existing questions on Udemy and apparently no other student has run into this before either, so I can’t offer any tips from other students.

      It certainly sounds like a permission issue, or perhaps a PATH issue. Is your PATH environment variable too long? I think there is an upper limit beyond which it just doesn’t work anymore. Might be a good idea to un-install and completely remove Anaconda (, reboot your PC, and try installing again as Administrator.

    Hi Team,
    I enrolled in Apache Spark with Scala – Hands-on with Big Data course from my organisation account udemy business. I need slides for that course. If it is possible, then please send me the slides via email. Hope you guys know my email. Thanks in advance.

    1. Frank Kane says:

      Please use the Q&A feature on Udemy for issues or requests there.

      1. balahari619 says:

        it was blocked by my organisation to ask question in Q&A also.

    Hi Frank,

    Thank you for your amazing courses.
    I took a course on Udemy and I have the certificate, is there a way to transfer it to sundog?
    I have already registered for 3 over here and want to aggregate all.

    1. Frank Kane says:

      I’m sorry, Udemy really doesn’t give us any way to transfer courses off-platform.

      1. Mohammad says:

        No problem.
        May I have the slides, please?
        Udemy is the worst platform!

        1. Frank Kane says:

          For which course? Usually slides can be downloaded from our course materials page for any given course.

          1. Mohammad says:

            The Ultimate Hands-on Hadoop. Tame Your Big Data!

  7. Frank Kane says:

    Yes, you’ll find a link to the slides near the bottom of the course setup page for that course.

    1. Mohammad says:

      Thanks, Frank!

    Hey Guys,
    I am trying to find a file called api-gateway-js-sdk for the “build a serverless App with AWS Lambda”. It’s not part of the downloads file?

    1. Frank Kane says:

      Hi, assuming you’re taking that course on Udemy (it’s not offered on this site) please use the Q&A feature there if you’re having trouble. As I recall, that SDK is automatically generated by the AWS API Gateway and the relevant lecture videos walk you through how to create it for your API.

    I’m interested in buying the Big Data bundle but I can’t because I previously bought the Spark 3 course and I get an error message when I tried to. I would be possible somehow to buy the bundle and get a discount since I already bought one of the courses from the bundle?
    Thank you very much.

    1. Frank Kane says:

      Hi, I’m afraid we can’t credit your previous purchases toward the older bundle deal. Rather than purchasing the bundle, I would recommend just enrolling in the Ultimate Hands-On Hadoop and Elasticsearch 8 courses individually as those are the main ones you’re missing based on your past purchases.

      Please check your email though; I’ve sent you something to help.

  10. mahongda says:

    I couldn’t purchase the Mega-Bundle. The error message is as shown below. Could you please help to check?

    You are already enrolled in “Mastering the System Design Interview”. Please remove “The Sundog Mega-Bundle” from your cart to proceed.

    1. Frank Kane says:

      You paid for one of the courses in the bundle already in 2021, and the system is just making sure you don’t end up paying twice for the same course.
      The easiest thing to do would be to create a new account under a different email address, and buy the bundle from there. Or, we can un-enroll you from the system design course if you’d prefer, which would let you buy it again through the bundle.

  11. Umesh Rajendran says:

    Not able to access it on my mobile. It is asking for enrollment. But I can access the course on my MacBook. Why is that so?

    1. Frank Kane says:

      You should be able to hit the “menu” button on mobile, and from there go to my courses / log in to access your courses.

    Regarding the Aws data engineer course should i have prior experience in AWS?
    I am working as a data analyst by the way

    1. Frank Kane says:

      From AWS’s exam guide:
      “The target candidate should have the equivalent of 2–3 years of experience in data engineering. The target candidate should understand the effects of volume, variety, and velocity on data ingestion, transformation, modeling, security, governance, privacy, schema design, and optimal data store design. Additionally, the target candidate should have at least 1–2 years of hands-on experience with AWS services. ”

      The course does not assume a lot of prior AWS experience, but I do think it would make more sense to start with a “cloud practitioner” certification or something. This is one of the more challenging AWS exams and probably shouldn’t be your first one.
