### Run server
```python
python -m run_server --custom_module_path ./your_code_here.py --expert_cls ExampleModule --hidden_dim 512 \
--dht_prefix "enter_name_here" --identity server1.id --host_maddrs "/ip4/0.0.0.0/tcp/31337"
# connect extra servers via --initial_peers ADDRESS_PRINTED_BY_ONE_OR_MORE_EXISTNG_PEERS # e.g. /ip4/123.123.123.123/rcp/31337
```
### Call remote inference
```python
hivemind-server --custom_module_path ./your_code_here.py --expert_cls ExampleModule --hidden_dim 512 --num_experts 1 \
--expert_pattern "expert.0.[0:9999]" --identity server1.id
