YC AI - Hackdot

To give a more exact estimate - if you don't use spot instances ($0.20/hour) it'll cost $0.90/hour, and if you do the suggested 70 hours of work for the course, that's $63. And then there's around $6/month cost for the EBS volume.

Not exactly.

The time you spend on the course, and the time spent by your instance running workloads are two completely separate things.

Your cost per-hour is accurate (plus a few bucks for an IP address), but the number of hours is off by an order of magnitude.

Also, I'm paying double that per instance per month for SSD using the provided scripts to build the instances. It's the smallest part of the cost, but I mention it because it can take newcomers to EC2 by surprise if they have an instance shut-down but consuming disk space.

I'm going through this course, but using Google cloud instead of AWS. I can confirm that at least the first Jupyter notebook works well for me.

I had to adapt the aws-install.sh script, but it was easy enough. I ended up using a snapshot instead of a persistent volume, as the monthly cost when you're not running is much cheaper. So I have a script to create a new instance and then restore that snapshot. It's faster than installing the dependencies each time).

Google Cloud has a $300 free trial for new users: https://cloud.google.com/free/

(Disclosure: I work for Google, but have no involvement in Google Cloud other than being a happy user)

Any chance you can share the adapted scripts? I assume they are easy to make, but the less barriers to entry the better.

Sure:

1) Create the instance the first time: https://gist.github.com/rahimnathwani/40ed3b6f496d377e3d17de...

2) SSH into the instance and run this script (replace anaconda mirror if your instance isn't in Asia, and definitely set the password hash): https://gist.github.com/rahimnathwani/b63ebc5900b832743d9e22...

3) After you've tested the server, snapshot the disk (using the web console) and destroy the instance and the persistent disk.

4) Run this script to recreate the instance and disk from the snapshot (replace with your snapshot name): https://gist.github.com/rahimnathwani/9019df33d4ad7ec4607413...

Buy a laptop with a GPU. If you are serious about learning AI, it's worth spending few hundred dollars to get a proper workstation.

I heard that nowadays it's possible to buy a laptop and a external GPU?

I have a mac, is it possible to really buy an external GPU??

Yes, but GPUs should only be consider for acceleration when there is insufficient local CPU power to accomplish something valuable. Otherwise, it's like buying a Ferrari to get groceries.
