what kind of runtime environment do I need

[zoumaxingjiulic]

Hello, thank you for your code.
If I want to run '/voxelmorph/voxelmorph/scripts/tf/train_template.py' or 'train_cond_template.py',what kind of runtime environment do I need, such as TensorFlow version, Keras version, etc. I tried TensorFlow 1.15gpu, TensorFlow 2.4.0gpu, but none of them worked.

In addition, is a reverse deformation field necessary during the training process of constructing templates.

Also, image_ Loss_ Is there a significant difference in using NCC or MSE for Func.

Looking forward to and thank you for your reply！
