Thank you for submitting your first PR!

Would you mind taking a look at the code format check flake8?
You could run runtests.sh --autofix
or run isort, black, flake8 one by one
Then run mypy ${your_added_script}

After you finalize the code, please add docstring reference in docs/source/apps.rst and make sure the document looks correct.
Please refer to https://github.com/Project-MONAI/MONAI/blob/dev/CONTRIBUTING.md#building-the-documentation
Thanks!

Please move the unit test to tests folder, not monai.apps

Looks good to me

Have you added rst for the script in monai.networks.blocks?

Please solve this error:
AttributeError: module 'torch.fft' has no attribute 'ifftshift'

Sorry I somehow missed this comment yesterday.
Could you provide more details? Is your pytorch up-to-date?

torch.fft.ifftshift is supported in the latest pytorch release: https://pytorch.org/docs/stable/generated/torch.fft.ifftshift.html
