tracing.py - delimiter for numpy.loadtxt() cannot be \n

[aleksandaratanasov]

The delimiter is actually \t (single tabulation). The following line

labels = np.loadtxt('synset_words.txt', dtype=str, delimiter='\n')

needs to be changed to

labels = np.loadtxt('synset_words.txt', dtype=str, delimiter='\t')

In CSV files new line means new row, that is a new entry. A delimiter is something the splits the columns in a single row.
