构建 SID catalog
SkillFiles & storageBuild SID trie catalogs for FlashRec from OpenOneRec RecIF packed mappings. Use when the user mentions sid-vocab-file, sid2pid, 物品目录, catalog, trie, flashrec --catalog, convert_recif_catalog, build_catalog.sh, or illegal SID rate.

--sid-vocab-file 需要逗号 key 的 JSON(如 "a,b,c,1")。RecIF 原始
sid2pid.json / sid2iid.json 用打包整数,必须先转换。不转换直接喂引擎会建错 trie。
默认(按源文件自动分层)
flashrec --catalog /path/to/OpenOneRec-RecIF/benchmark_data
RecIF 打包整数(a*8192^2+b*8192+c)会写成 4 层 data/catalogs/sid2pid_beamrec_l4.json(末段 1 = <|sid_end|>)。逗号 key 按源文件段数原样保留。data/ 已 gitignore,不要提交生成物。
| 旗标 / 变量 | 默认 | 含义 |
|---|---|---|
--catalog / DATA_DIR | (必填) | RecIF benchmark_data 目录或 sid2pid.json |
--catalog-task / TASK | video | video / product / both |
--catalog-levels / LEVELS | (自动) | 覆盖推断层数。3 = "a,b,c";4 = 在 3 层 RecIF 后追加 {sid_begin, sid_end} |
--catalog-out / OUT_DIR | data/catalogs | 输出目录或 JSON 文件 |
flashrec --catalog sid2pid.json --catalog-out out.json
flashrec --catalog sid2pid.json --catalog-out out.json --catalog-levels 3
DATA_DIR=/path/to/benchmark_data bash scripts/build_catalog.sh
与服务参数对齐
服务只需 --model-path + --sid-vocab-file。引擎从 tokenizer 读取
<s_a_*> / <|sid_begin|> / <|sid_end|>,再结合 catalog 层数推断 token
区间、codebook 大小和 boundary。启动日志会打印
Inferred --sid RANGE/SIZES (boundary B) from tokenizer + catalog。
4 层 catalog(key "a,b,c,1")把结束符做成末层 codebook,生成序列为
[a, b, c, sid_end],结束符 logprob 计入 sequence_score。3 层 catalog
("a,b,c")的 range 只含 codebook,boundary 包在后面。
tokenizer 不用这套命名时才显式传 --sid。换模型后会重新推断,不要把旧
checkpoint 的 token id 抄过去。
检查
- 输出 JSON 根对象的 key 是逗号分隔整数,不是打包十进制
- RecIF 打包源默认 4 段且末段为
1;逗号源保持原段数(不要把真实第 4 码改成1) - 启动服务后
invalid_rate应为 0;若 ~0.28,说明仍在跑开放词表(没挂 vocab 文件)
