First try with label studio

Label studio is easy to install and open, but once I started download data online, problem happens, didn’t know exactly which button wors for what, and AI’s instruction makes me confusing. Four hours later, I finally uploaded a picture and started. Without any knowledge about python and code, it’s so difficult to understand the logic, and hard to locate my mistake during training.
So hard to learnt by myself. Anyone has passed through this process successfully? Any advice is highly appreciated.
