# Run Chattensor

## With vanilla python:
python server.py --neuron.model_id mock --wallet.name sn1 --wallet.hotkey v1 --netuid 1 --neuron.tasks math --neuron.task_p 1 --neuron.device cpu --subtensor.network local

## With PM2:
```
EXPECTED_ACCESS_KEY="hey-michal" pm2 start app.py --interpreter python3 --name app -- --neuron.model_id mock --wallet.name sn1 --wallet.hotkey v1 --netuid 1 --neuron.tasks math --neuron.task_p 1 --neuron.device cpu
```

basic testing
```
EXPECTED_ACCESS_KEY="hey-michal" python app.py --neuron.model_id mock --wallet.name sn1 --wallet.hotkey v1 --netuid 1 --neuron.tasks math --neuron.task_p 1 --neuron.device cpu
```
add --mock to test the echo stream
