PerceptualLoss Bug

[CugAgo]

Describe the bug
When I use PerceptualLoss, if the loss is too low, it may occur "RuntimeError: Function ‘SqrtBackward0‘ returned nan values in its 0th output", I will provide the specific error location later.

@CugAgo Please provide an error location and if it's the same root cause, I'll submit a PRQ (if this is a 👍 issue for a first time contributor).

也许与此问题有关？https://github.com/richzhang/PerceptualSimilarity/pull/139/files

请提供错误位置，如果是相同的根本原因，我将提交 PRQ（如果这是👍第一次贡献者的问题）。

yes, I'm sorry for forgetting to provide accurate error information yesterday. In the normalize_tensor function, I think this bug can be fixed through this method, good job!

Great. #8414

May I ask when this source code will be updated to the MONAI library? Can I update the corresponding version through pip
