|
||||
|
||||
## 下一步建议
|
||||
|
||||
### 高优先级修复
|
||||
1. **重新下载模型权重** (12B Layer 6, 31B Layer 40, E2B Audio)
|
||||
2. **修复Audio NaN问题** (E4B, 12B Audio Tower)
|
||||
3. **修复Batch Embedding NaN**
|
||||
4. **运行Vision测试**
|
||||
|
||||
### 中优先级优化
|
||||
1. 提高权重预读取成功率 (60% → 80%)
|
||||
2. 进一步优化Layer构造时间
|
||||
3. 添加更多benchmark测试
|
