broadcast_tensor and mse_loss are ops that are not implemented in ONNX currently. To get unblocked need to modify functional.py as per below comment

mse_loss implementation in https://github.com/pytorch/pytorch/blob/master/torch/nn/functional.py#L2682 uses 2 ops that are not implemented: broadcast_tensors() and mse_loss(). Working around this to get unblocked, made a patch:
#expanded_input, expanded_target = torch.broadcast_tensors(input, target)
expanded_input = input + torch.zeros(target.size())
expanded_target = target + torch.zeros(input.size())
#ret = torch._C._nn.mse_loss(expanded_input, expanded_target, _Reduction.get_enum(reduction))
t = expanded_input - expanded_target
t = t * t
ret = torch.mean(t)

q_bias and v_bias are always const, so commenting them out
Previous iterations i tried to redefine StableDropout to inherit from nn.Dropout, but it led to regression in model stats. Could not figure out why. If i do change this way there is no regression. Something was missing with just redefining StableDropout. |
