Hey there! We've found the following might help you get unblocked faster:

• 🧵 BUILD TIME OUT

• 🧵 python fastAPI application that uses torch and transformers failing on build

• 🧵 Increase time out

If you find the answer from one of these, please let us know by solving the thread!

Hello,

Thank you for your kind words about Railway - we appreciate that feedback.

The increased build times are not due to any fault or regression on our infrastructure. Build times are determined by the dependencies and processes in your application's build. Looking at your build logs, there's an extensive dependency tree that's consuming most of the build time.

The main contributors to your build time include:

The PyTorch ecosystem (torch, transformers, sentence-transformers) plus NVIDIA CUDA packages - PyTorch alone is 888MB and CUDA libraries add approximately 3GB, consuming 4-5 minutes of build time.

You're also installing multiple overlapping ML/AI libraries, multiple cloud SDKs (Google Cloud, Firebase, AWS), various communication services (Twilio, Vonage, Slack SDK, SendGrid), and multiple database drivers simultaneously.

Your 11+ minute build time could drop to 2-3 minutes by removing unused packages and creating separate requirements files for different environments to avoid installing unnecessary dependencies.

To achieve faster deployments for your bug fixes, optimizing your build by reducing these dependencies will be the most effective approach.

Best,

Brody

Thanks, I will get back to you if something else happens.
