I have a ValueError in code Utils.py

[IamSVP94]

I tried to run op.py with the next command:

python op.py --dataset utk --regression global --experiment_setting coral --im_path UTKFace

But I have a problem with inhomogeneous part of sequence.
The full error text:

  File "/home/vid/hdd/projects/PycharmProjects/MWR2/code/op.py", line 62, in <module>
    global_regression(args, train_data, test_data, sampling=sampling, sample_rate=sample_rate)
  File "/home/vid/hdd/projects/PycharmProjects/MWR2/code/Prediction.py", line 99, in global_regression
    refer_idx, refer_idx_pair = select_reference_global_regression(train_data, pair_idx, np.array(loss_total), limit=1)
  File "/home/vid/hdd/projects/PycharmProjects/MWR2/code/Utils.py", line 98, in select_reference_global_regression
    y_1_idx_tmp, y_2_idx_tmp = idx[row], np.array(pair_idx)[idx[0]][column]
ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (6582,) + inhomogeneous part.

How to fix it?
