How does one install the stable diffusion webUI for use with TensorRT?
-To install the stable diffusion webUI, one needs to create a new folder under the C drive, open a command prompt from this folder, and use the code from automatic1111's GitHub page followed by 'git clone'. Then, change to the dev branch using the commit hash from the stable diffusion commit hash page.
What is the purpose of installing the development version of NVIDIA's TensorRT?
-The development version of NVIDIA's TensorRT is installed to optimize the performance of deep learning models for inference, which is particularly useful for speeding up image generation with stable diffusion webUI.
How does exporting the TensorRT engine to the checkpoint work?
-To export the TensorRT engine to the checkpoint, one needs to select the model they want to incorporate the engine into from the stable diffusion checkpoint. Different TensorRT engines are required for each image size, so one would export engines for various sizes such as 512x512, 1024x1024, and others as needed.
What is the impact of using TensorRT on image generation speed?
-Using TensorRT can make image generation significantly faster. For instance, with an RTX4090, the number of iterations per second can reach around 51.12 compared to the usual 30, making the process about 1.5 times faster.
How does TensorRT affect VRAM consumption during image generation?
-TensorRT seems to reduce VRAM consumption compared to normal mode. For example, when generating a 512x512 image and upscaling it to 2x with Hi-Res Fix using TensorRT, the VRAM usage was 5.04GB, whereas with SD Unet set to none, it was 6.19GB.
What is the recommended method for upscaling images when using TensorRT?
-The future of image upscaling with TensorRT might be better served by using the img to img method rather than using high resolution fix, as it can be faster and more efficient.
What is SDXL and how does it relate to TensorRT?
-SDXL is a feature that is currently only available on the dev branch of stable diffusion webUI. It allows for the export of a 1024x1024 TensorRT engine for use with specific base models, which can significantly increase the speed of image generation.
