torch.Tensor.repeat, as its documentation notes, is divergent from np.repeat but similar to np.tile. Now that torch.tile is implemented, we can deprecate torch.repeat in favor of torch.tile by doing the following:

• deprecate torch.Tensor.repeat in favor of torch.tile for a release
  • verify torch.tile implements the same behavior as np.tile and torch.repeat (see discussion and linked PRs)
  • audit and update internal callsites so PyTorch doesn't throw warnings by default
• remove torch.repeat for a release (possibly requires writing an upgrade for serialized torchscript)
• restore torch.repeat analogous to np.repeat

np.repeat is a top 50 NumPy function, and torch.Tensor.repeat (note that torch.repeat does not exist) is popular with hundreds of uses within Facebook.
