|
|
- [ ] Build with CUDA 13.0 fails with clear error message
|
|
- [ ] Build with CUDA 12.9 succeeds with "✅ CUDA 12.9 detected"

### Essential Commands
|
|
|
|
**Check CUDA Version**:

|
|
|
**Switch to CUDA 12.9**:
|
|
```bash
|
|
sudo rm /etc/alternatives/cuda
|
|
sudo ln -s /usr/local/cuda-12.9 /etc/alternatives/cuda
|
|
nvcc --version # Verify
|
|
```
|
|
|
|
**Validate Environment**:
|
|
```bash
|
|
./scripts/validate_cuda_env.sh
|
|
```
|
|
|
|
**Build with Validation**:
|
|
```bash
|
|
cargo clean
|
|
cargo build -p ml --release --features cuda
|
|
```
|
|
|
|
**Verify Binary**:
|
|
```bash
|
|
ldd target/release/examples/train_tft_parquet | grep cublas
|
|
# Expected: libcublas.so.12
|
|
```
|
|
|
|
**Deploy to Runpod**:
|
|
```bash
|
|
python3 scripts/runpod_deploy.py --gpu-type "RTX A4000"
