Here we show some interesting results as an example of the dreambooth script.
Prompt: A ‘sks’ dog in a bucket.
Prompt: A ‘sks’ dog in Acropolis.
Prompt: A ‘sks’ dog in front of Eiffel tower.
Prompt: A ‘sks’ dog mecha robot.

Latency times are started directly before the text encoding (CLIP) and stopped directly after the output image decoding (VAE). For framework we use the Torch Automated Mixed Precision (AMP) for FP16 computation. For TRT, we export the various models with the FP16 acceleration. We use the optimized TRT engine setup present in the deployment directory to get the numbers in the same environment as the framework.
GPU: NVIDIA DGX A100 (1x A100 80 GB)
