要修改Langchain-Chatchat Web页面的标签栏文字和页面左上角的LOGO,您可以参考以下信息:

  1. 修改标签栏文字
    标签栏的文字是在 webui.py 文件中通过 st.set_page_config 函数设置的。您可以在该文件中找到以下代码并进行修改:

    st.set_page_config(
        "Langchain-Chatchat WebUI",
        os.path.join("img", "chatchat_icon_blue_square_v2.png"),
        initial_sidebar_state="expanded",
        menu_items={
            'Get Help': 'https://github.com/chatchat-space/Langchain-Chatchat',
            'Report a bug': "https://github.com/chatchat-space/Langchain-Chatchat/issues",
            'About': f"""欢迎使用 Langchain-Chatchat WebUI {VERSION}!"""
        }
    )

    您可以将 "Langchain-Chatchat WebUI" 修改为您想要的标题[1]

  2. 修改页面左上角的LOGO
    LOGO的引用在多个地方。一个是在侧边栏中,使用 os.path.join 函数指定路径 "img/logo-long-chatchat-trans-v2.png"。您可以在 webui.py 文件中找到相关代码并修改路径以指向您自己的LOGO文件:

    with st.sidebar:
        st.image(
            os.path.join(
                "img",
                "logo-long-chatchat-trans-v2.png"
            ),
            use_column_width=True
        )

    另外,在前端组件中,LOGO也通过不同的类型引用,如 'flat'、'3d'、'combine' 和 'text'。您可以在 frontend/src/components/Logo/index.tsx 文件中找到这些引用并进行相应的修改[2][3]

希望这些信息能帮助您完成毕设项目的修改!

要删除Langchain-Chatchat项目中与上传图片相关的Web内容,您需要修改文件 libs/chatchat-server/chatchat/webui_pages/dialogue/dialogue.py。具体来说,您应该删除或注释掉以下代码部分:

  1. 注释掉的文件上传代码:

    # uploaded_file = st.file_uploader("上传附件", accept_multiple_files=False)
    # files_upload = process_files(files=[uploaded_file]) if uploaded_file else None
  2. 与图片上传相关的代码:

    upload_image = None
    def on_upload_file_change():
        if f := st.session_state.get("upload_image"):
            name = ".".join(f.name.split(".")[:-1]) + ".png"
            st.session_state["cur_image"] = (name, PILImage.open(f))
        else:
            st.session_state["cur_image"] = (None, None)
        st.session_state.pop("paste_image", None)

通过删除或注释掉这些部分,您将有效地从项目中移除与图片上传相关的Web内容[1]

To save your changes, copy your custom theme into the clipboard and paste it into the[theme] section of your .streamlit/config.toml file.
.streamlit/config.toml file找不到文件位置,请问位置在哪里

dosubot bot commented Apr 10, 2025

The .streamlit/config.toml file is typically located in the root directory of your Streamlit project. If it doesn't exist, you can create it manually. Simply create a new directory named .streamlit in the root of your project, and then create a config.toml file inside that directory. This file is used to configure various settings for your Streamlit application, including custom themes.
