Regarding the batch size used for different model training

@glenn-jocher
I saw in README that you set batch-size like this. As far as I know, batch-size is generally 2 to the n-th power, but what is the setting of 40 and 24 here? Or is it arbitrarily set according to the different GPU memory usage?

[glenn-jocher]

@Zengyf-CVer arbitrary for single-GPU, or use --batch -1 for autobatch.

@glenn-jocher
Is this autobatch designed based on the maximum memory of a single GPU?

[glenn-jocher]

@Zengyf-CVer it's an experimental feature only available for single-GPU training at the moment. See #5092

Thank you very much.
