Buffer dtype mismatch, expected 'long' but got 'long long'

[Semihal]

I run torchreid/metric/rank_cyclib/test_cython.py and receive:

  File "C:\Users\Semihal\Documents\Projects\deep-person-reid\torchreid\metrics\rank.py", line 201, in evaluate_rank
    use_metric_cuhk03
  File "torchreid\metrics\rank_cylib\rank_cy.pyx", line 25, in torchreid.metrics.rank_cylib.rank_cy.evaluate_cy
    cpdef evaluate_cy(distmat, q_pids, g_pids, q_camids, g_camids, max_rank, use_metric_cuhk03=False):
  File "torchreid\metrics\rank_cylib\rank_cy.pyx", line 33, in torchreid.metrics.rank_cylib.rank_cy.evaluate_cy
    return eval_market1501_cy(distmat, q_pids, g_pids, q_camids, g_camids, max_rank)
ValueError: Buffer dtype mismatch, expected 'long' but got 'long long'

I have same error when start evaluating phase.
