试了一下直接返回全部值，没有看到value相关的信息，但是在tooltip里面又能看得见具体的数值。

@BpointA 试下这个代码

nodes = [
        {"name": "category1"},
        {"name": "category2"},
        {"name": "category3"},
        {"name": "category4"},
        {"name": "category5"},
        {"name": "category6"},
    ]

    links = [
        {"source": "category1", "target": "category2", "value": 10},
        {"source": "category2", "target": "category3", "value": 15},
        {"source": "category3", "target": "category4", "value": 20},
        {"source": "category5", "target": "category6", "value": 25},
    ]
    c = (
        Sankey()
        .add(
            "sankey",
            nodes,
            links,
            edge_label_opt=opts.LabelOpts(is_show=True),
            linestyle_opt=opts.LineStyleOpts(opacity=0.2, curve=0.5, color="source"),
            label_opts=opts.LabelOpts(position="right"),
        )
        .set_global_opts(title_opts=opts.TitleOpts(title="Sankey-基本示例"))
    )

        )
        .set_global_opts(title_opts=opts.TitleOpts(title="Sankey-基本示例"))
    )

可以了，感谢！
我排查了一下，是我在label_opt中设置了格式={b}，去掉之后就好了。
