enabled must be a bool (got str) error so I can't command to txt2img...

[kotran88]

Hello :)
I have issue with error saying
enabled must be a bool (got str).

I commanded with command below
python scripts/txt2img.py --prompt "a professional photograph of an astronaut riding a horse" --ckpt C:\Users\pedro\Downloads\512-base-ema.ckpt --H 512 --W 512 --steps 30 --seed -1 --n_samples 1 --n_iter 1 --precision=autocast

on scripts/txt2img.py,

I changed
from torch import autocast
to
from torch.cuda.amp import autocast

on below,
opt.device is 'cpu'
and error caused

enabled must be a bool (got str)
on precison_scope(opt.device),\

what may be the problem?

    precision_scope = autocast if opt.precision=="autocast" or opt.bf16 else nullcontext
    
    with torch.no_grad(), \
        precision_scope(opt.device), \
        model.ema_scope():
            all_samples = list()
            for n in trange(opt.n_iter, desc="Sampling"):
