torch.hub.load('nvidia/DeepLearningExamples:torchhub','nvidia_tacotron2') HTTP Error 404

I get for the
https://api.ngc.nvidia.com/v2/models/nvidia/tacotron2pyt_fp32/versions/1/files/nvidia_tacotron2pyt_fp32_20190306.pth
an HTTP Error 404 message.
is there a new place and if yes, can we update the hub?
