When i run my program, it shows errors: AxisError: axis 1 is out of bounds for array of dimension 1
idx_tmp[0:2, :] = np.concatenate((np.array([[-1], [-1]]), idx[0:2, :]), axis=1) ---> 99
<array_function internals> in concatenate(*args, **kwargs)
AxisError: axis 1 is out of bounds for array of dimension 1
Could you provide a reproducible example?
