The above results may be due to the IEEE floating representation. However, when arr has shape [1, 3, 321, 481], jt.mean(arr) offers unexpected results with error ~4.3e-3 as shown below.
Same result in my case, which leads to imprecise SSIM.
A simple testing code example

This may be a bug in jittor, and it has brought inconsistent results with numpy or pytorch in terms of SSIM metrics.
