ModuleAttributeError: 'MLP' object has no attribute 'DL'

[vishyML]

Hi, I tried running theory_exp.py . I get the following error when trying to to collapse the net to symbolic expression. It will be great help if you can help me resolve it.

Thank you,
Vishy.

Perhaps there is some error under the @Property "def DL" function. The way to debug is to remove the @Property in the DL definition, and when calling the function, use DL() instead of DL. Then you can debug where the error comes from. After debugging, undo the above operations and resume the @Property
