Incorrect Argument Default for DeepSpeed Multi-node Training

[jomayeri]

System Info

pip install accelerate.

Information

• [ ] The official example scripts
• [ ] My own modified scripts

Tasks

• [ ] One of the scripts in the examples/ folder of Accelerate or an officially supported no_trainer script in the examples folder of the transformers repo (such as run_no_trainer_glue.py)
• [ ] My own task or dataset (give details below)

Reproduction

Run accelerate for multi-node training.

Expected behavior

Accelerate is setting the default DeepSpeed hostfile to None this overrides the DeepSpeed default of /job/hostfile. Overriding this default is causing issues with users attempting multi-node trading. Please change the default to match DeepSpeed's default.

Hi @jomayeri, thanks for reporting ! Make sense to switch to the DeepSpeed's default. Would you like to open the PR ? Otherwise, I can do it ! cc @muellerzr
