신경망을 가르치려고 시도하면서 deeplearning.net에서 Theano 튜토리얼을 통해 작업을 시작했습니다. 방금 튜토리얼의 모든 코드 행을 복사하여 붙여 넣었으므로 예상치 못한 오류가 발생했습니다. 틀린 것은 무엇이든간에 작은 것이고 나는 단지 그것을 살펴보고 있지만 어떤 도움이 많이 감사 할 것입니다. 감사합니다Theano 튜토리얼 : UnusedInputError : theano.function

UnusedInputError: theano.function was asked to create a function computing outputs given certain inputs, but the provided input variable at index 0 is not part of the computational graph needed to compute the outputs: inc.
To make this error into a warning, you can pass the parameter on_unused_input='warn' to theano.function. To disable it completely, use on_unused_input='ignore'.
