the code I used to plot alphas

alphas.py

def load_alpha_data(log_file):
  data = [[], [], []]
  with open(log_file) as log:
    for line in log:
      if line.startswith('data'):
        num = int(line[5])
        row = [float(x) for x in line[7:].split()]
        data[num].append(row)
  return data

def plot_all_alphas(data, only_3=False):
  for k in range(3):
    arr = numpy.array(data[k])
    if only_3:
      arr = arr[:, [4, 5, 7]]
      arr = numpy.exp(arr) / numpy.exp(arr).sum(axis=1)[:, None]
    pyplot.figure(figsize=(15, 3))
    for i in range(arr.shape[1]):
      pyplot.plot(arr[:, i])
    if only_3:
      pyplot.legend(['X', 'R', 'Y'])
    pyplot.xlabel('alpha_{}'.format(k))
    pyplot.show()
