EMD runtime error: Please let me know what is the error as the same code works perfectly in a different project on the same PC

[kaali-billi]

match = emd_cuda.approxmatch_forward(xyz1, xyz2)
IndexError: Dimension out of range (expected to be in range of [-2, 1], but got 2)

This is the error I am getting after input :

EMD = earth_mover_distance().cuda()
np1 = np.asarray(TSS.points)
np2 = np.asarray(RSS.points)
T1 = torch.from_numpy(np1).type(torch.float32).cuda()
T2 = torch.from_numpy(np2).type(torch.float32).cuda()
l1 = EMD(T2, T2)
