Keep with it if you can. Again, I told have any hard experience in that area, but I'm a software developer by trade, and a geography person (kind of) by academics. Physical Anthro and Geo have some crossover, and both stand to be going in the direction of applying some DL techniques at present and going forward. Particularly in the areas of remote sensing if you want a rabbit hole to dive into :) Unix can be a nightmare, and you just have to suffer it for a while to get used to the patterns. Otherwise, My recommendation is to just work slowly through the bits and pieces. The amount of projects that people seem to have just slapped together in a weekend is daunting, but far from reality for everyone. The expectation of fast progress is the enemy of actual progress.
