启动gorse后，master.log错误日志

```
{"level":"error","ts":1695738823.6536405,"msg":"failed to get popular items","error":"strconv.ParseFloat: parsing \"男_社交\": invalid syntax"}

```

Start by reproducing the startup condition and inspect master.log around the “failed to get popular items” entry. Trace where the value "男_社交" is passed to numeric parsing and identify the expected data format. Done means startup no longer emits this error and popular-item retrieval still works.
