What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

I recently picked up this book, and it's been a game-changer for me. If you're into AI image generation, this book is the new gold.They walk you through setting up everything you need - CUDA, PyTorch, the works - without making it feel like a slog. And when they get into the nitty-gritty of diffusion models, they somehow make it all click. The authors have this knack for explaining tricky concepts in a way that just makes sense. Whether you're just dipping your toes into this stuff or you've been at it for a while, you'll get something out of this book.All in all, if you're even slightly curious about AI image generation, grab a copy. Trust me, you won't regret it!

From the outset, the author sets a clear and engaging tone, making complex concepts accessible to a broad audience. The book's structure is well-organized, beginning with an introduction to the fundamentals of stable diffusion processes and their significance in various applications. This foundational knowledge is crucial for readers who may not have a strong background in statistics or stochastic processes.One of the book's standout features is its practical approach. The author does an excellent job of not just explaining theoretical concepts but also demonstrating how to implement them using Python. The step-by-step examples and code snippets are particularly useful, providing readers with hands-on experience and making it easy to follow along. The inclusion of real-world applications further enhances the learning experience, showcasing how these techniques can resolve practical issues and save valuable time.

If you ever tried to write your own application for Stable Diffusion, you'd notice that the prompt is limited to only 77 tokens, and you will receive no warning. You need to chunk your big prompt and use a package like Compel to make it work. I learned it the hard way, the book would have told me immediately. Adding LoRas and LyCos are not as easy as doing so in A1111 or ComfyUI. I only hoped I had this book way before it was launched. The author is one of the developers of the Diffusers library and he knows what he is doing. He is also a talented writer. It's not a beginner's book and you are buying it because you are hard core programmer. I bought this book twice in the pre-order by mistake and received a copy as present from a great friend.

The book outlines strategies to refine performance, manage VRAM effectively, and utilize community innovations like LoRAs and textual inversion. It introduces powerful tools like ControlNet and IP-Adapter, enhancing control and quality in image generation. The exploration extends to video creation with AnimateDiff and the art of crafting effective prompts, including the use of LLMs for automation. Additionally, it offers a detailed walkthrough on training a Stable Diffusion LoRA from the ground up, making it an invaluable resource for both novice and advanced users in the field of AI-driven art.
