rmongodb Tutorial

This is a quick document aimed at highlighting the basics of what you might want to do using MongoDB and R. I am coming at this, almost completely, from a SQL mindset.

Install

The easiest way to install, I believe, is

Installing CUDA 12.1.1 + PyTorch nightly + Python 3.10 on Ubuntu 22.10

Should you keep your NVIDIA driver?

CUDA 12.1.1 toolkit is gonna offer to install Nvidia driver 530 for us. It's from New Feature branch. It's likely to be newer than the default Nvidia driver you would've installed via apt-get (apt would prefer to give you 525, i.e. Production Branch).

If you're confident that you already have a new enough Nvidia driver for CUDA 12.1.1, and you'd like to keep your driver: feel free to skip this "uninstall driver" step.

But if you're not sure, or you know your driver is too old: let's uninstall it. CUDA will install a new driver for us later.

	First install pip for Python2. Download the get-pip.py file from https://bootstrap.pypa.io/get-pip.py
	$ cd <download location>
	$ sudo -H python ./get-pip.py

	Installing pip also installs Python3
	To run Python3
	$ python3

	Install pip3 by just executing the same file as in the step above, but this time using Python3
	$ sudo -H python3 ./get-pip.py

	Qualtrics.SurveyEngine.addOnload(function() {
	var maxWords = 0; //update as needed, 0=no limit

	var input = q.find(".InputText");
	input.after("<div style='font-size:0.8em;float:right'>Word count: <span class='wordCount'>0</span><span class='maxWords'></span></div>");
	var display = q.find(".wordCount");
	if(maxWords > 0) q.find('.maxWords').text("/"+maxWords);
	countWords(input.get(0));
	input.on("input", function() { countWords(this) });
	input.blur(function() { this.value = this.value.trim(); });
