x_dict.update({value: x_dict[key]}) at line:156 register key-variable's value as value-variable's value. And key-variable remains.
At next step, key-variable are sometimes overwritten but sometimes not. For example, AddLoss copies an input dictionary, and overwrite old one to updated one.
the key-variable is not updated. So the effect of reccurence is ignored.
Solution
hotfix: delete future variable by replace_dict_keys.
raise exception when some variables are overwritten by sampling (now preparing).
This is hot fix of IterativeLoss.
Issue: a bug of IterativeLoss
