No default session is registered. Use `with sess.as_default():` or pass an explicit session to `run(session=sess)`

hello,while I was running your code, there was a problem:
Traceback (most recent call last):
File "eval.py", line 147, in
main()
File "eval.py", line 82, in main
tf.global_variables_initializer().run()

raise ValueError("Cannot execute operation using run(): No default "
ValueError: Cannot execute operation using run(): No default session is registered. Use with sess.as_default(): or pass an explicit session to run(session=sess)
Could you give me some advice about this error please,looking forward to your reply.

This code only supports tf 1.4.

Thank you for your patient reply before.Your advice is helpful to me.I succeeded in getting the test results, but I wanted to get the deformation field and the warped image.Is that right to replace keys = ['pt_mask', 'landmark_dists', 'jaccs', 'dices', 'jacobian_det', ] in eval.py with keys = ['real_flow', 'image_fixed', 'warped_moving']? Are there any specific changes that need to be made elsewhere?
