# Wave 3 Agent 10: Quick Reference
|
|
|
|
**Status**: ✅ PARTIAL SUCCESS - Fixed target errors, ML crate has unrelated issues
|
|
|
|
---
|
|
|
|
## 🎯 What We Fixed
|
|
|
|
### 1. DQN Trainable Adapter ✅
|
|
**File**: `ml/src/dqn/trainable_adapter.rs` (Line 219-230)
|
|
```rust
|
|
// Vec → HashMap for safetensors save
|
|
let mut tensors: HashMap<String, Tensor> = HashMap::new();
|
|
let tensors_refs: HashMap<_, _> = tensors.iter().map(|(k, v)| (k.as_str(), v.clone())).collect();
|
|
candle_core::safetensors::save(&tensors_refs, &safetensors_path)
|
|
```
|
|
|
|
### 2. MAMBA Trainable Adapter ✅
|
|
**File**: `ml/src/mamba/trainable_adapter.rs`
|
|
|
|
**Fix 1** (Line 253): Accuracy field
|
|
```rust
|
|
accuracy: self.metadata.training_history.last().and_then(|e| e.accuracy),
|
|
```
|
|
|
|
**Fix 2** (Line 271-281): Async runtime
|
|
```rust
|
|
let runtime = tokio::runtime::Runtime::new().map_err(|e| MLError::ModelError(...))?;
|
|
runtime.block_on(async { model_clone.save_checkpoint(checkpoint_path).await })?;
|
|
```
|
|
|
|
### 3. Feature Imports ✅
|
|
**File**: `ml/src/inference.rs` (Line 30)
|
|
```rust
|
|
use crate::features_old::UnifiedFinancialFeatures;
|
|
```
|
|
|
|

|
|
|
|
## ⏸️ Blocked: Can't Run Tests
|
|
|
|
**Why**: ML crate has 94 compilation errors in unrelated modules
|
|
|
|
**Next Steps**:
|
|
1. Fix `MLSafetyError::FeatureExtractionError` variant (missing)
|
|
2. Remove `pub mod parquet_io;` from `features_old.rs` (line 3513)
|
|
3. Fix Decimal → f64 conversions in `features/unified.rs`
|
|
|

|
|
|
|
## 📊 Results
|
|
|
|
- ✅ **3/3 target files fixed** (DQN, MAMBA, imports)
|
|
- ❌ **0/16 tests run** (blocked by ML crate errors)
|
|
- ⏸️ **94 errors remain** (in dependencies)
|
|

## 🔄 Next Agent
|
|
|
|
**Mission**: Fix ML crate compilation errors
|
|
**Priority**:
|
|
1. `ml/src/safety/mod.rs` - Add FeatureExtractionError variant
|
|
2. `ml/src/features_old.rs` - Remove parquet_io module
|
|
3. `ml/src/features/unified.rs` - Fix Decimal conversions
|
|
|
|
**Command to verify**:
|
|
```bash
|
|
cargo build -p ml --lib
|
|
```
|
|
|
|
**Command to run tests** (after fixes):
|
|
```bash
|
|
cargo test -p ml_training_service --test job_queue_tests --no-fail-fast
|
|
```
