How can change aggregation of a metric or get the total result of a metric

[Freed-Wu]

By default,

from torchmetrics.image.psnr import PeakSignalNoiseRatio
metric = PeakSignalNoiseRatio()
metric(img1, target1)
metric(img2, target2)
...
metric(img100, target100)
metric.compute()
# print the average of 100 pair of image's PSNRs

How can get

from torchmetrics.image.psnr import PeakSignalNoiseRatio
metric = PeakSignalNoiseRatio(aggregation = "concatenate")
metric(img1, target1)
metric(img2, target2)
...
metric(img100, target100)
metric.compute()
# print a list of 100 pair of image's PSNRs

TIA!

Hey, did you figure out how to do this?
