# bloom-demo
Early dev prototype for decentralized bloom. Not for public eyes **yet** .
```python
if you.read(this) and you.name not in '@timdettmers @borzunov @mryab @greenfatguy '.split():
you.go("away")
```
# install

# tests
```bash
# run one bloom block for a few steps
python -m cli.inference_one_block --config cli/config.json # see other args
# convert model from HF hub to a distributed format
MY_WRITE_TOKEN=TODO_WRITE_TOKEN_FROM_https://huggingface.co/settings/token
python -m cli.convert_model --model bigscience/bloom-6b3 \
--output_path ./converted_model --output_repo bigscience/test-bloomd-6b3 \
--use_auth_token $MY_WRITE_TOKEN # ^-- todo replace output repo with something you have access to
# minimalistic server with non-trained bloom blocks
python -m cli.run_server --prefix smol --block_config bigscience/bloom-6b3 --num_blocks 2 \
--identity_path ./server1.id --host_maddrs /ip4/127.0.0.1/tcp/31337
# when running multiple servers:
# - give each server a unique --identity_path (or remote --identity_path arg when debugging)
# - if running multiple servers on the same machine, give each a unique port (last integer in --host_maddrs, 0 means random port)
# - when running over the internet, change --host_maddrs according to https://learning-at-home.readthedocs.io/en/latest/user/dht.html#running-across-the-internet
# - each server except first should have --initial_peers pointing to one of pre-existing servers
