sampling loop time step

[MichaelJacob914]

Currently running the code, and after 1000 steps it starts the 'sampling loop time step' but says it will do this 3125 times and is estimated to take about a week. Is this a part of training, and why is it taking so long/will it do this every 1000 steps? Thanks

It seems as though this was caused by calculate_fid set to true in my trainer statement.

I think it is because of using ddim_sampling. If your sampling_timesteps < timesteps, it will make the model use ddim_sample.
If you want to decrease the fid loop numbers, you can set the trainer.num_fid_samples smaller.
The default num_fid_samples is 50000.
