Launch training with accelerate launch arg error

Launching training with accelerate launch raise argument errors

Traceback (most recent call last):
  File "/usr/local/bin/accelerate-launch", line 8, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.7/dist-packages/accelerate/commands/launch.py", line 690, in main

    mixed_precision = PrecisionType(args.mixed_precision.lower())
AttributeError: 'NoneType' object has no attribute 'lower'

However, you can still start the training by calling the script with python

python train_unconditional.py ...

@anton-l could you take a look here?

Hi @radames! You need to run accelerate config before launching the scripts for the first time, I've added that step to the training README now: https://github.com/huggingface/diffusers/tree/main/examples#installing-the-dependencies
Thanks for reporting!

Thanks @anton-l
