Parallax 실행시 Tensorflow error 문의 #27
Description
안녕하세요,
과제를 진행 중, Parallax에서 실행시에만 발생하는 문제가 생겨 문의 드리고자 합니다.
위의 코드로 training을 수행시 Parallax 에서만 아래의 문제가 발생합니다.

ValueError: Cannot feed value of shape (784,) for Tensor u'Placeholder:0', which has shape '(?, 784)'
Primary job terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.
mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:
Process name: [[59384,1],0]
Exit code: 1

session run에 들어가는 tensor shape이 문제인듯 한데,
다른 실행 코드들도 같은 방식으로 잘 동작하며 feed 전의 모양은 해당하는 tensor의 shape에 알맞은 모양임을 확인하였습니다.
해당 라인 이후로 feed data가 parallax 내부에서 변환되는 부분이 있는지 알고 싶습니다.
