云服务器部署DeepSeek Janus-Pro生成图片实战

序

本文主要研究一下如何在腾讯云HAI-GPU服务器上部署DeepSeek Janus-Pro来进行文本生成图片

步骤

选择带GPU的服务器

到deepseek2025试用一下带GPU的服务器

下载Janus

git clone https://github.com/deepseek-ai/Janus.git

安装依赖

cd Janus
pip install -e .

安装gradio

pip install gradio

安装torch

pip uninstall torch torchvision torchaudio -y
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121

运行示例

python demo/app_januspro.py --device cuda

输出示例如下

Python version is above 3.10, patching the collections module.

Using a slow image processor as `use_fast` is unset and a slow processor was saved with this model. `use_fast=True` will be the default behavior in v4.48, even if the model was saved with a slow processor. This will result in minor differences in outputs. You'll still be able to use a slow processor with `use_fast=False`.

You are using the default legacy behaviour of the . This is expected, and simply means that the `legacy` (previous) behavior will be used so nothing changes for you. If you want to use the new behaviour, set `legacy=False`. This should only be set if you understand what it means, and thoroughly read the reason why this was added as explained in https://github.com/huggingface/transformers/pull/24565 - if you loaded a llama tokenizer from a GGUF file you can ignore this message.

Some kwargs in processor config are unused and will not have any effect: ignore_id, add_special_token, num_image_tokens, mask_prompt, sft_format, image_tag.

小结

自己部署实际还是挺多麻烦的(最开始是在mac上跑，遇到CUDA_HOME问题，后来是找了cpu版本的，遇到没有GPU的问题，最后用了一个带GPU的服务器才跑成功)，会遇到各种依赖问题，还有GPU等配置问题，另外就是网络访问问题，所以实际折腾下来就是，如果没有其他特殊需求，还是乖乖用云服务的api吧。
