How to capture index of highest valued array from predict function?

Question

[[0.12673968 0.15562803 0.03175346 0.6858788 ]] This is how my predict function is giving its output, I want to fetch the index of the highest value. Tried this: pred= pred.tolist() print(max(pred)) index_l=pred.index(max(pred)) print(index_l)

But it seems to output only 0.

Printing max(pred) is giving the output: [0.12673968076705933, 0.1556280255317688, 0.031753458082675934, 0.6858788132667542]

The network uses sequential with hidden layers (embedding, BiLSTM, BiLSTM, Dense, Dense)
