The meaning and usage of sample_log

[jqliu09]

Hey, I saw the stored "sample_log" pictures in the Image_logs. But Actually the generated images in "sample_log" is different from the reconstructed ones. So could I ask what is that usage?

    if sample:
        # get denoise row
        samples, z_denoise_row = self.sample_log(cond={"c_concat": [c_cat], "c_crossattn": [c]},
                                                 batch_size=N, ddim=use_ddim,
                                                 ddim_steps=ddim_steps, eta=ddim_eta)
        x_samples = self.decode_first_stage(samples)
        log["samples"] = x_samples
        if plot_denoise_rows:
            denoise_grid = self._get_denoise_row_from_list(z_denoise_row)
            log["denoise_row"] = denoise_grid
