ValueError: object __array__ method not producing an array

discrete_sigma = 10 ** np.linspace(np.log10(min_sigma), np.log10(max_sigma), num_sigma + 1)[1:]
ValueError: object array method not producing an array

so I print the min_sigma and max_sigma，min_sigma: <class 'float'> 0.02, max_sigma: <class 'torch.Tensor'> tensor(2.0200),how this problem should be solved
