Hi,

I wanted to use Accelerate on 1 GPU. I answered the questions as below:

```auto
(env) niels:~/python_projects/community-events-1$ accelerate config
In which compute environment are you running? ([0] This machine, [1] AWS (Amazon SageMaker)): 0
Which type of machine are you using? ([0] No distributed training, [1] multi-CPU, [2] multi-GPU, [3] TPU): 0
Do you want to run your training on CPU only (even if a GPU is available)? [no]:no
Do you want to use DeepSpeed? [yes/NO]: no
How many processes in total will you use? [1]: 1
Do you wish to use FP16 or BF16 (mixed precision)? [NO/fp16/bf16]: no

```

But when printing the environment, use\_cpu is set to True:

```auto
(env) niels@brutasse:~/python_projects/community-events-1$ accelerate env

Copy-and-paste the text below in your GitHub issue

- `Accelerate` version: 0.6.1

        - distributed_type: NO
        - mixed_precision: no

        - num_processes: 1
        - machine_rank: 0
        - num_machines: 1

To reproduce my error, I am running the following script (that uses Accelerate): [community-events/huggan/pytorch/lightweight\_gan at main · huggingface/community-events · GitHub](https://github.com/huggingface/community-events/tree/main/huggan/pytorch/lightweight_gan).

Thanks!

Should be fixed once this PR is merged: [bug by muellerzr · Pull Request #311 · huggingface/accelerate · GitHub](https://github.com/huggingface/accelerate/pull/311)
