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

• This code works.

from accelerate import Accelerator

accelerator = Accelerator(log_with="tensorboard", project_dir="./log")

• This code fails to create tensorboard log.

from accelerate import Accelerator

accelerator_log_kwargs = {}
accelerator_log_kwargs["project_dir"] = args.output_dir
accelerator = Accelerator(log_with="tensorboard", **accelerator_log_kwargs)

Expected behavior

Create log file.

args.output_dir

What is the value of args.output_dir? If it's the same as in your first code snippet, "./log", the two snippets should be identical.

[Zhuofeng-Li]

args.output_dir value is "./log".

But the second can not create log dir.

Can you show more code? Where exactly does the error occur? What is the full error message?
