ABY3 error：Unsupported share type: 0.

[hgyuhaoyang]

Dear developers:
I tried to use tfe.reshape() function with ABY3 protocol, but the program reports an error：Unsupported share type: 0.
I printed share_type of cipher using pond protocol, but there is no share type of pond protocol cipher.
I wanna know how to use tfe.reshape() function with ABY3 protocol, thanks a lot.
