Training details

Some examples of training details, including:

  1. VOC12 dataset in this wandb link.
  2. Cityscapes dataset in this wandb link (w/ 1-teacher inference).

In details, after clicking the run, you can checkout:

  1. overall information (e.g., training command line, hardware information and training time).
  2. training details (e.g., loss curves, validation results and visualization)
  3. output logs (well, sometimes might crash ...)
