Hi, I noticed that in upsampling block, the code does Conv1dWithInitialization and then InterpolationBlock. [code link](https://github.com/ivanvovk/WaveGrad/blob/721c37c216132a2ef0a16adc38439f993998e0b7/model/upsampling.py#L61) But in paper network structure it looks like the reverse order of yours.  Could you please confirm this? Thanks
