# MAMBA-2 Tensor Shape Fix - Executive Summary
|
|
|
|
**Agent 128** | **Date**: 2025-10-14 | **Status**: ✅ FIXED
|
|
|
|
---
|
|
|
|
## Problem
|
|
MAMBA-2 training failed with layer norm shape mismatch:
|
|
```
|
|
Error: Layer norm shape mismatch [60, 512] vs [256]
|
|
```
|
|
|
|
## Root Cause
|
|
`DbnSequenceLoader` created tensors **without batch dimension**:
|
|
- Expected: `[batch=1, seq_len=60, d_model=256]`
|
|
- Actual: `[seq_len=60, d_model=256]`
|
|
|
|
This caused MAMBA-2 to interpret sequence positions as batch items, breaking temporal ordering.
|
|
|
|
## Fix
|
|
**File**: `ml/src/data_loaders/dbn_sequence_loader.rs` (lines 596-607)
|
|
|
|
```diff
|
|
- let input = Tensor::from_slice(&features, (self.seq_len, self.d_model), &self.device)?;
|
|
+ let input = Tensor::from_slice(&features, (1, self.seq_len, self.d_model), &self.device)?;
|
|
|
|
- let target_tensor = Tensor::from_slice(&target, (1, self.d_model), &self.device)?;
|
|
+ let target_tensor = Tensor::from_slice(&target, (1, 1, self.d_model), &self.device)?;
|
|
```
|
|
|
|
## Verification
|
|
✅ `cargo check -p ml --features cuda` - **SUCCESS**
|
|
✅ `cargo build --release --example train_mamba2_dbn` - **SUCCESS**
|
|
✅ Training launched (waiting for build lock due to concurrent jobs)
|
|
|
|
## Command to Resume Training
|
|
```bash
|
|
CUDA_VISIBLE_DEVICES=0 cargo run --release -p ml --features cuda --example train_mamba2_dbn -- \
|
|
--epochs 200 \
|
|
--batch-size 16 \
|
|
--learning-rate 0.0001 \
|
|
--sequence-length 60 \
|
|
--hidden-dim 256 \
|
|
--state-dim 64 \
|
|
--data-dir test_data/real/databento/ml_training \
|
|
--output-dir ml/trained_models/production/mamba2 \
|
|
--use-gpu \
|
|
> /tmp/mamba2_cuda_training.log 2>&1 &
|
|
```
|
|
|
|
## Impact
|
|
- **Memory**: No change (same elements, correct shape)
|
|
- **Performance**: No impact
|
|
- **Correctness**: ✅ Fixed temporal ordering in state space model
|
|
- **Breaking Changes**: None
