Instructions to use ethicalabs/Echo-DSRN-114M-Base with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use ethicalabs/Echo-DSRN-114M-Base with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="ethicalabs/Echo-DSRN-114M-Base", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained("ethicalabs/Echo-DSRN-114M-Base", trust_remote_code=True, dtype="auto")

Training stability on AMD ROCm (distributed backend, gloo vs nccl)

Use gloo, NOT nccl for the distributed backend on single-GPU ROCm.nccl is designed for multi-GPU NVIDIA communication.

On AMD ROCm (HIP), the NCCL comm teardown races with HIP device release during process exit, causing a ProcessGroupNCCL::abortCommsFromMap → getDevice HIP error (exit code 134).

The fix is dist.init_process_group(backend="gloo", ...)

Gloo handles single-process groups cleanly on both CUDA and ROCm with no teardown race.
