Accessing section-specific data

Some mentors have coordinated with the methodology staff and DSMLP to provide only the students in their section access to data on DSMLP. This data lives in section-specific folders that only the students in their section have access to.

Here’s how to launch a server on DSMLP in a way that you can access this section-specific data. For the purposes of this example, we will assume you want to use the vanilla launch-scipy-ml.sh launch script, but these steps work with any launch script and flags. Also, note that here “team” and “section” mean the same thing; by “team” we don’t mean your project’s team.

  1. ssh onto DSMLP as usual. Don’t run any launch scripts yet.
  2. Run launch-scipy-ml.sh -W DSC180A_FA22_A00 -G list. Note that this won’t actually launch a server – instead, this will list all of the groups you are a part of. You should see a row that contains your capstone section number for the “Team,” like DSC 180A - A14 [88137] in the example below. Copy the “Team ID” (dsc180aa1488137100014352 in the example below).

Note: If you don’t see the right team information at this step, contact Suraj.

  1. Run launch-scipy-ml.sh -W DSC180A_FA22_A00 -G <teamid>, with <teamid> replaced with the Team ID you copied earlier. If you’re in section A14 like in the example above, you’d run launch-scipy-ml.sh -W DSC180A_FA22_A00 -G dsc180aa1488137100014352.

  2. After your server launches, run ls. You should see three folders – private, public, and teams. Your home directory is in private (that’s where all your code should live). The public folder contains files that the methodology course staff may share with the entire course.

  3. To find your section-specific data, cd into teams. Run ls to see a list of all of the teams in the course and identify the name of yours. This may look like the example below. If, again, you’re in section A14, your team-specific folder is "dsc-180a---a14-[88137]" (the quotes are important). If you cd into that folder, you’ll see the files that your mentor uploaded for you!

All you need to do now is access the data in your team’s folder from your code in the private folder! For instance, from a script at the root of your private folder, a path to a file in your team’s folder might be "../teams/dsc-180a---a14-[88137]/example.txt".
