L1DIS metric support problem

[XianchaoZhang]

Hi IceClear,
I just try to train CLIP-IQA+ on KonIQ-10k as your instruct:

python tools/train.py configs/clipiqa/clipiqa_coop_koniq.py

But encounter the following error, it seems only PSNR/SSIM supported.
Did this mean I have to change the config option L1DIS to PSNR/SSIM?

I too face this problem. Any idea how to fix this?

[IceClear]

It seems the env is not correct. You may try reinstall the env or switch to another implementation. See #13

A simple fix that worked for me in the current version of code.
Replace this line with
allowed_metrics = {'PSNR': psnr, 'SSIM': ssim, 'L1DIS': l1dis}
and import l1dis here
