Args:
noise_scheduler (`NoiseScheduler`):
An object containing the noise schedule parameters, specifically `alphas_cumprod`, which is used
to compute the SNR values.
timesteps (`torch.Tensor`):
A tensor of timesteps for which the SNR is computed.

Returns:
`torch.Tensor`: A tensor containing the computed SNR values for each timestep.
