模型推理

输入图像url+prompt(单张图片+单轮对话)

另有本地上传图像形式，请进入项目查看

You will be able to see the image once I provide it to you. Please answer my questions.###Human: <Img><ImageHere></Img> <TextHere>###Assistant:"9

将图像上传到本地后的file_path+prompt(多张图片+单轮对话)

效果展示

输入：描述这张图片，使用中文

输出：这张图片显示了一个女性角色，穿着红色和白色的服装，手持一根金色的剑。她的头发是白色的，眼睛是红色的。她站在一张草地上，手持剑的柄子。这个角色看起来像是一个英雄，她的服装和装备显示出她的力量和勇气
