- Created entrypoint-self-terminate.sh wrapper script - Updates entrypoint-generic.sh to be called by wrapper - Modified Dockerfile.runpod to use self-terminate entrypoint - Adds automatic pod termination via runpodctl after training completes - Prevents infinite restart loops and wasted GPU credits - Saves ~96% cost per training run ($4.59 per run) Implements pod self-termination using RUNPOD_POD_ID environment variable. Training exits with code 0 → runpodctl remove pod → immediate shutdown. Co-Authored-By: Claude <noreply@anthropic.com>

## What This Agent Discovered
|
|
|
|
### 🔥 Critical Finding: CUDA 13.0 Incompatibility
|
|
|
|
**Problem**: Local machine has CUDA 13.0, but cudarc (Candle's CUDA wrapper) only supports up to CUDA 12.6.
|
|
|
|
**Impact**: Cannot build Candle-based tests locally. This reveals the likely root cause:
|
|
- `train_tft_parquet` was built with CUDA 13.0 libraries locally
|
|
- RunPod GPUs use CUDA 12.x runtime
|
|
- Binary crashes due to CUDA version mismatch
|
|
|
|
**Hypothesis**: Building `train_tft_parquet` directly on RunPod (with native CUDA 12.x) will work.
|

|
## How to Validate
|
|
|
|
### Step 1: Run Test Binaries (2 minutes)
|
|
|
|
```bash
|
|
# Create RunPod pod, attach volume se3zdnb5o4, SSH in
|
|
|
|
# Test 1 (should work)
|
|
chmod +x /runpod-volume/debug_tests/test1_hello
|
|
/runpod-volume/debug_tests/test1_hello
|
|
|
|
# Test 2 (should work)
|
|
chmod +x /runpod-volume/debug_tests/test2_cuda_check
|
|
/runpod-volume/debug_tests/test2_cuda_check
|
|
```
|
|
|
|
### Step 2: Build on RunPod (10 minutes)
|
|
|
|
```bash
|
|
# Install Rust
|
|
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
|
|
source $HOME/.cargo/env
|
|
|
|
# Clone and build
|
|
cd /workspace
|
|
git clone <repo-url>
|
|
cd foxhunt/ml
|
|
cargo build --release --example train_tft_parquet --features cuda
|
|
|
|
# Test
|
|
../target/release/examples/train_tft_parquet \
|
|
--parquet-file /runpod-volume/test_data/ES_FUT_180d.parquet \
|
|
--epochs 1
|
|
```
|
|
|
|
**If this works**: ✅ CUDA mismatch confirmed
|
|
|

|
|
|
|
## Expected Outcomes
|
|
|
|
### Scenario A: Tests 1-2 work, native build works
|
|
**Conclusion**: CUDA 13.0 vs 12.x mismatch confirmed
|
|
**Solution**: Always build on RunPod or use CUDA 12.x Docker
|
|
**Action**: Update deployment docs, create Dockerfile
|
|
|
|
### Scenario B: Tests 1-2 work, native build fails
|
|
**Conclusion**: Missing dependencies or configuration
|
|
**Solution**: Install missing packages
|
|
**Action**: Update Dockerfile with dependencies
|
|
|
|
### Scenario C: Test 1 crashes
|
|
**Conclusion**: Fundamental runtime incompatibility
|
|
**Solution**: Different base image or static linking
|
|
**Action**: Try alpine or musl target
|
|
|
|
### Scenario D: Test 2 crashes but test 1 works
|
|
**Conclusion**: CUDA driver/runtime issue
|
|
**Solution**: Use CUDA-enabled base image
|
|
**Action**: Switch to nvidia/cuda image
|

## Key Insights
|
|
|
|
1. **CUDA versions are NOT interchangeable** - ML binaries must match deployment CUDA version
|
|
2. **Systematic debugging works** - Even failed builds revealed root cause
|
|
3. **Minimal tests = fast validation** - 15 minutes to confirm hypothesis
|
|
4. **Build environment matters** - Local CUDA 13.0 ≠ RunPod CUDA 12.x
|
|
