The __init__.py imports many things at module level. The first import is signal_bridge. Let me check which specific import is hanging by testing each one.

The process is hanging and getting killed after 5s with exit code 143 (128+15 = SIGTERM). This is a timeout issue during import. Let me check if there's something in the signal_bridge or another module that's trying to connect to a network service during import.

Actually, looking at signal_bridge.py, it imports redis.asyncio which should be fine. But let me check if there's any module-level code that could hang.


Output:
13:    import redis.asyncio as redis
48:    redis = None  # Will fail gracefully if used
57:    redis_url: str = "redis://localhost:6379"

84:        if hasattr(config, 'redis_url'):
86:            self.redis_url = config.redis_url
91:            self.redis_url = config['redis_url']
95:        self._redis: Optional[redis.Redis] = None
107:        """Initialize Redis connection on actor start."""
110:        # Create Redis connection
111:        self._redis = redis.from_url(self.redis_url)
126:        # Close Redis connection
127:        if self._redis:
128:            asyncio.create_task(self._redis.close())
144:                messages = await self._redis.xread(
155:            except redis.ConnectionError as e:
156:                self.log.error(f"Redis connection error: {e}")


I see - the signal_bridge uses redis but doesn't connect at import time. Let me check if maybe there's something in another imported module that hangs. Let me test importing the modules one by one from the __init__.py.

Direct import works! So the issue is with the package import mechanism. There might be something in the import system or a circular import. Let me check if there's a pycache issue.

I see something important: `import 'nautilus_dolphin' # <_frozen_importlib_external.NamespaceLoader object at 0x7ff9b67e9a90>`. This means nautilus_dolphin is being imported as a namespace package, not a regular package. This is because there's no `__init__.py` in the nautilus_dolphin directory!

Let me check.


ls -la /mnt/dolphinng5_predict/nautilus_dolphin/__init__.py 2>/dev/null || echo "No __init__.py in nautilus_dolphin/"


Output: No __init__.py in nautilus_dolphin/

I see - the nautilus_dolphin directory is actually a git repository or has the code directly, but it doesn't have an __init__.py file in the root! The actual package is in `/mnt/dolphinng5_predict/nautilus_dolphin/nautilus_dolphin/` (note the duplication).

So the structure is:
- /mnt/dolphinng5_predict/nautilus_dolphin/ (repo root, no __init__.py)
  - nautilus_dolphin/ (actual package, has __init__.py)
    - nautilus/ (subpackage)

That's why I need to add `/mnt/dolphinng5_predict/nautilus_dolphin` to sys.path. But the namespace loader might be causing issues.

Let me check if maybe there's a .pth file or something creating this namespace issue.

No dolphin in site-packages. Let me check if there's something in the path that's causing this namespace issue. The problem is that Python is treating nautilus_dolphin as a namespace package because there's no __init__.py.

Let me create an __init__.py file to fix this.

I shouldn't use pkg_resources since it's deprecated. Let me just make it a regular package or simply remove the declare_namespace.

Now the problem is that Python is finding the root nautilus_dolphin package but can't find the nautilus_dolphin.nautilus subpackage. This is because the import is looking for:
- nautilus_dolphin (found at /mnt/dolphinng5_predict/nautilus_dolphin/)
- nautilus_dolphin.nautilus (should be at /mnt/dolphinng5_predict/nautilus_dolphin/nautilus/)

But actually the structure is:
- nautilus_dolphin (at /mnt/dolphinng5_predict/nautilus_dolphin/)
- nautilus_dolphin.nautilus_dolphin (at /mnt/dolphinng5_predict/nautilus_dolphin/nautilus_dolphin/)
- nautilus_dolphin.nautilus_dolphin.nautilus (at /mnt/dolphinng5_predict/nautilus_dolphin/nautilus_dolphin/nautilus/)

So the import path should be `nautilus_dolphin.nautilus_dolphin.nautilus.launcher`.

But wait, looking at the launch_paper_portfolio.py file:
```python
sys.path.insert(0, str(PROJECT_ROOT / 'nautilus_dolphin'))
from nautilus_dolphin.nautilus.launcher import NautilusDolphinLauncher
```

This means the code expects to import `nautilus_dolphin.nautilus` where `nautilus_dolphin` is found at `/mnt/dolphinng5_predict/nautilus_dolphin/nautilus_dolphin/` (the subdirectory).

The issue is that I added an `__init__.py` to the repo root, which changed the import behavior. Let me remove it and try a different approach.


rm /mnt/dolphinng5_predict/nautilus_dolphin/__init__.py && echo "Removed root __init__.py"


Output: Removed root __init__.py

Command executed successfully.


Let me understand the import structure better. The sys.path has:
1. `/mnt/dolphinng5_predict` (PROJECT_ROOT)
2. `/mnt/dolphinng5_predict/nautilus_dolphin` (the repo root)

When importing `nautilus_dolphin.nautilus.launcher`:
- Python looks for `nautilus_dolphin` in sys.path
- It finds `/mnt/dolphinng5_predict/nautilus_dolphin/nautilus_dolphin` (a directory)
- Since there's no `__init__.py` in `/mnt/dolphinng5_predict/nautilus_dolphin/`, Python 3 treats it as a namespace package
- Then it looks for `nautilus` inside `nautilus_dolphin`

Actually, wait - let me trace through this more carefully. The path is `/mnt/dolphinng5_predict/nautilus_dolphin/nautilus_dolphin/`. When we add `/mnt/dolphinng5_predict/nautilus_dolphin` to sys.path, Python should be able to find `nautilus_dolphin` (the inner directory) as a package.

Let me test this directly.


source /home/dolphin/siloqy_env/bin/activate && timeout 10 python3 << 'EOF' 2>&1
import sys
# Only add the repo root to path
sys.path.insert(0, '/mnt/dolphinng5_predict/nautilus_dolphin')

print('[TRACE] Importing nautilus_dolphin...')
import nautilus_dolphin
print(f'[TRACE] nautilus_dolphin location: {nautilus_dolphin.__file__}')
print(f'[TRACE] nautilus_dolphin path: {nautilus_dolphin.__path__}')

print('[TRACE] Importing nautilus_dolphin.nautilus...')
from nautilus_dolphin.nautilus import launcher
print('[TRACE] launcher imported!')
EOF


Output:

Command failed with exit code: 124.

Failed with exit code: 124


The import is hanging again. This is the same namespace package issue. When there's no `__init__.py` in the root nautilus_dolphin directory, Python 3 treats it as a namespace package and might have issues.

Let me try a different approach - let me check how the existing code in prod/ handles this.


Output:
import argparse
import yaml
from pathlib import Path
from datetime import datetime, timezone
import sys
import json

HCM_DIR = Path(__file__).parent.parent
sys.path.insert(0, str(HCM_DIR / 'nautilus_dolphin'))

from nautilus_trader.backtest.engine import BacktestEngine, BacktestEngineConfig

def main():

Command executed successfully.


I see - `run_nautilus.py` does the same thing: adds `HCM_DIR / 'nautilus_dolphin'` to path and then imports from `nautilus_dolphin.nautilus`. Let me test if this file works.


source /home/dolphin/siloqy_env/bin/activate && cd /mnt/dolphinng5_predict/prod && timeout 10 python3 -c "

Same hanging issue! This is definitely a problem with the namespace package. Let me try running the actual run_nautilus.py file to see if it behaves differently.


source /home/dolphin/siloqy_env/bin/activate && cd /mnt/dolphinng5_predict/prod && timeout 10 python3 run_nautilus.py --help 2>&1 | head -10


Command executed successfully.


Interesting, running the file directly works but the import test hangs. Let me check if maybe it's a __pycache__ issue or something specific to the interactive mode.


source /home/dolphin/siloqy_env/bin/activate && cd /mnt/dolphinng5_predict/prod && timeout 10 python3 run_nautilus.py --help 2>&1


Command failed with exit code: 124.

Failed with exit code: 124


It also hangs! Let me try with unbuffered output.


source /home/dolphin/siloqy_env/bin/activate && cd /mnt/dolphinng5_predict/prod && timeout 10 python3 -u run_nautilus.py --help 2>&1


It seems like the scripts are all hanging when importing from nautilus_dolphin.nautilus. Let me try a simpler approach - just import nautilus_trader and see if that works.


source /home/dolphin/siloqy_env/bin/activate && timeout 5 python3 << 'EOF' 2>&1
print('[1] Importing nautilus_trader...')
import nautilus_trader
print(f'[1] OK, version: {nautilus_trader.__version__}')

print('[2] Importing nautilus_trader.config...')
from nautilus_trader.config import TradingNodeConfig
print('[2] OK')
EOF


Output:
[1] Importing nautilus_trader...
[1] OK, version: 1.219.0
[2] Importing nautilus_trader.config...
[2] OK

Command executed successfully.


nautilus_trader works fine. The issue is specific to nautilus_dolphin. Let me check if maybe there's a circular import or something in the nautilus_dolphin.nautilus package.

Actually, let me try something - let me just run the paper trader with a timeout and see what error we get, rather than trying to debug the import issue.


source /home/dolphin/siloqy_env/bin/activate && cd /mnt/dolphinng5_predict/prod && timeout 30 python3 -u launch_paper_portfolio.py 2>&1 | tee /tmp/paper_trader_output.log; echo "Exit code: ${PIPESTATUS[0]}"


Output: Exit code: 124

Command executed successfully.


Still timing out with no output. Let me try running it in a way that captures more debug info.


source /home/dolphin/siloqy_env/bin/activate && cd /mnt/dolphinng5_predict/prod && timeout 30 python3 -v -u launch_paper_portfolio.py 2>&1 | head -200

I can see that `nautilus_dolphin.monitoring.prometheus_exporter` and `nautilus_dolphin.monitoring.alerter` are being imported. The import is actually working! The hang must be happening later. Let me continue monitoring and check what's happening at the end.

The imports are happening and then cleanup is happening! This suggests the script is actually running but hitting a timeout. Let me try running it with a longer timeout and see if there's any output.

The script is now running and we can see the output. The error is:
```
Failed to initialize Nautilus: Missing required argument 'config_path'
```

This is the same error I saw earlier. The issue is in the launcher.py when creating ImportableActorConfig for TradeLoggerActor - it's missing the `config_path` argument.

Let me fix this by checking the launcher code and adding the missing config_path.


The paper trader is now running with siloqy_env. The error is:
```
Missing required argument 'config_path'
```

This is a bug in the launcher - the TradeLoggerActor config is missing a `config_path`. Let me fix it:

I need to add `config_path` to the TradeLoggerActor ImportableActorConfig. Let me check what the trade_logger config looks like and add the appropriate config_path.

Now let me run the paper trader again to see if it progresses further.
