TypeError: read() got an unexpected keyword argument 'ignoregamma' (Solution Provided)

[JY251]

I have encountered the following error. I have found a solution so I will share with you.

python run_nerf.py --config configs/fern.txt
Traceback (most recent call last):
  File "run_nerf.py", line 878, in <module>

    return imageio.imread(f, ignoregamma=True)

    result = file.read(index=0, **kwargs)
TypeError: read() got an unexpected keyword argument 'ignoregamma'

This issue is similar to Issue #190 in the original bmild/nerf repository, which is implemented based on Tensorflow (but not PyTorch).
Similar with this, to resolve it, update line 110 of load_llff.py as follows:

            return imageio.imread(f, apply_gamma=True)

I hope this helps!

Updating the version of imageio to 2.9.0 also resolved the issue.
