[!warning] This version is experimental. Please refer to the newer versions pinned above to avoid any complexities.👆👆👆
[!IMPORTANT] This is a copy of the model weights from the https://huggingface.co/deepseek-ai/DeepSeek-OCR model. These weights cannot be used for other purposes. If you wish to do so, please visit the original model page.
Previously, inference with the model https://huggingface.co/deepseek-ai/DeepSeek-OCR ran smoothly on transformers==4.46.3. However, running it on the latest versions of transformers caused compatibility issues with LlamaAttention. We have addressed and fixed the problem, and the model now runs smoothly with the latest transformers (v4.57.1) or any compatible version.
This page, which includes the model weights and corrected configuration, fixed the issue and allowed transformers inference to run smoothly.
[!note] Last updated: 3:00 PM (IST), DEC 04, 2025.
transformers: 4.57.1
torch: 2.6.0+cu124 (or) the latest version (i.e., torch 2.9.0)
cuda: 12.4
device: NVIDIA H200 MIG 3g.71gb
Currently supported up to `transformers==4.57.2`. Support for Transformers v5 will be added soon.
