Hi:
DMML35 looks like the course code for the Supervised Machine Learning with SAS Viya class which uses that code for the class folder. If you are installing the course data on your own company installation of SAS Viya, you may need to have your SAS Viya Administrator provide you with a write access folder as the location for the data.
It might be easier to use the Hands-On Lab that we provide with the paid version of the course. We give each student access to a pre-configured image on the SAS Viya for Learners server.
If you are taking our self-study version of the class, the location for the data on the server is shown in the course notes as the LIBNAME statement you show. However, you can find the directions for using SAS Viya for Learners 3.5 (which is the platform for the Hands-on Lab for the course), on the Course Materials tab, as shown below:
And this document shows you how to set up the data and your copy of the folder for class. On page 1, you see this explanation for how to use the class data on SAS Viya for Learners:
Then inside the document, it shows a path somewhat similar to what you show but the location is in the Users folder on the SAS Viya for Learners server (step 12):
And then later in Step 12, it shows the path without a leading slash:
But if you are running this class on your own installation of SAS Viya, then you'll need to get the contents of the zip file into a folder on your company SAS Viya server where you have write access.
