Theano 'Expected An Array-like Object, But Found A Variable': Using Scan & Categorical_crossentropy

I'm trying to sum multiple loss in theano but I can't make it work. I'm using the categorical crossentroy. Here is my code: import numpy as np import theano import theano.tenso

Solution 1:

I found my problem, it's really a stupid one.

loss = loss_cal(answers, predictions)

This is wrong, as predictions is the theano matrix, I should have been using pred.

pred = []
for i in range(0, max_nbr):
    temp = np.ones(8)
    temp[i] = temp[i] + 5
    temp = temp/sum(temp)
    pred.append(temp)

It works now with loss = loss_cal(answers, pred) Thanks anyway
