ValueError: need more than 2 values to unpack #6
Comments
I have met the similar problem, I think this problem is caused by the mismatch between the number of ops and the number of return values,。 Obviously,lastbatch_err don't have corresponding op. |
dense_decoded,lastbatch_err , lr = \
sess.run([model.dense_decoded, model.lrn_rate],
val_feed) sees.run() only return two values,you just need to remove "lastbatch_err ",good luck |
@QiangXie @980044579 thanks,I have solve it by your solutions. |
