2 years ago Hi @G-1nOnly, both modes are for evaluation: eval is the default evaluation mode and test-optim is a special mode that
- enables backprop for test-time optimization (disabled by default), and
- samples random rays instead of rendering the entire image, as in training mode (here and here).
You can think of the test-optim mode as the training (optimization) mode for evaluation. Hope this helps!
I would like to ask a question about the difference between test and evaluate, I notice that for the "test-optim" mode, you would still perform some refinement and for the "eval" part, you evaluate the results, so if I have trained a model, I'm going to test the model and regenerate the figure, I should use the "test-optim" mode or the "eval" mode, from my understanding, I should use the "test-optim" mode? I'd appreciate it if you answered my questions about the difference about test and evaluate.
By the way, great works and thank you in advance!!!
