How can I make gif visualizations like those shown in the README?

You can use the make_gif.py to make your own gif visualizations.

How can I speed up model training?

If you are only using one thread (i.e., --nthreads 1), then training will likely be very slow. Determine how many threads the machine you are using has and use as many as possible.

How do I fix "ValueError: num_samples should be a positive integer value, but got num_samples=0"?

This error comes up when the script can't find the data to train on. Check that the training_filenames and validation_filenames in the configuration file are valid.

How much GPU memory do I need?

It is recommended to have at least 11GB of GPU memory. See GPU Memory and Input Size section of the Configuration File Guide for instructions on how to adjust the input image size to use less memory.

Do I need to use a GPU?

You can run model inference without a GPU, but model training will take far too long without a GPU.
