test wont work unless --config_path is provided?

Hi, thanks for the great library.

I have two questions:

When running: accelerate config, then accelerate test, the script doesnt work and throws the error: FileNotFoundError: [Errno 2] No such file or directory: 'None' Which means the default path is None rather than in the cache folder?

However it does work perfectly when using: accelerate config --config_file /path/config.json accelerate test --config_file /path/config.json

1. If I want to use evaluation on one GPU only (not distributed evaluation), it is mentioned:

You can perform regular evaluation in your training script, if you leave your validation dataloader out of the prepare() method. In this case, you will need to put the input data on the accelerator.device manually.

If I do this, do I also need to wrap my code inside: if accelerator.is_main_process(): ?

Thanks a lot!

No, pip install accelerate installs the last released version 😃
