Module Error?

[AegonLin]

When I execute "python deep_sort_app.py -h" in cmd error is "Traceback (most recent call last): File "deep_sort_app.py", line 14, in from deep_sort.tracker import Tracker File "C:\Users\user\Downloads\deep_sort-master\deep_sort\tracker.py", line 5, in from . import linear_assignment File "C:\Users\user\Downloads\deep_sort-master\deep_sort\linear_assignment.py", line 4, in from sklearn.utils.linear_assignment_ import linear_assignment ModuleNotFoundError: No module named 'sklearn.utils.linear_assignment_"

C:\Users\Administrator\AppData\Local\Programs\Python\Python37\lib\site-packages\sklearn\utils\linear_assignment_.py:21: DeprecationWarning: The linear_assignment_ module is deprecated in 0.21 and will be removed from 0.23. Use scipy.optimize.linear_sum_assignment instead. DeprecationWarning)

so you should reinstall a lower sklearn

from scipy.optimize import linear_sum_assignment as linear_assignment


    # indices = linear_assignment(cost_matrix)
    row_indices, col_indices = linear_assignment(cost_matrix)

    matches, unmatched_tracks, unmatched_detections = [], [], []
    for col, detection_idx in enumerate(detection_indices):
        if col not in col_indices:
            unmatched_detections.append(detection_idx)
    for row, track_idx in enumerate(track_indices):
        if row not in row_indices:
            unmatched_tracks.append(track_idx)
    for row, col in zip(row_indices, col_indices):
        track_idx = track_indices[row]
