DeepMemory: overload of add_ is deprecated

[clementpoiret]

Hi,

I'm currently trying DeepMemory, but with latest pytorch (1.7.0), I get the following warning. Do you have any update for DeepMemory?

/content/utils/optimizers/deepmemory.py:129: UserWarning: This overload of add_ is deprecated:
	add_(Number alpha, Tensor other)
Consider using one of the following signatures instead:
	add_(Tensor other, *, Number alpha) (Triggered internally at  /pytorch/torch/csrc/utils/python_arg_parser.cpp:882.)
  exp_avg.mul_(beta1).add_(1 - beta1, grad)

Thanks,
Clément
