could you tell me how to resolve it? Thanks

I think it may be caused by different version, because i don't have that problem.
My development environment is Anaconda3+spyder 3.2.7+tensorflow1.2.1 (My computer don't have GPU, so I don't try tensorflow-gpu ).
In the code 'var_list=self.parameter_list' , I set the struct of 'parameter_list' like this:
[[W_1 ,b_1],[W_2 , b_2],...,[W_out, b_out]] , which may cause your problem.
It's can be solved by transforming 'parameter_list' to [ W_1 ,b_1,W_2 , b_2,...,W_out, b_out ](='new_parameter_list') . Just setting a new list 'new_parameter_list' and let 'var_list=new_parameter_list'.
Wish this method can solve your problem!

I have changed the struct of 'parameter_list'. You can download new code and try again~

Thank you so much. It works.

I fixed some bug again
