The order of upsampling_dilations

[junjun3518]

Hi! My name is Junhyeok Lee and I appreciate your works!
Maybe I found a slight mistake in your config file.

WaveGrad/configs/default.json

Lines 6 to 12 in 721c37c

	"upsampling_dilations": [
	[1, 2, 1, 2],
	[1, 2, 1, 2],
	[1, 2, 4, 8],
	[1, 2, 4, 8],
	[1, 2, 4, 8]
	],

In Wavegrad Appendix A, they mentioned "The dilation factors of four convolutional layers are 1, 2, 4, 8 for the first three UBlocks and 1, 2, 1, 2 for the rest". Since they listed kernel sizes starting from the block closest to x(5,5,3,2,2), it seems that upsampling_dilations should be [[1,2,4,8]*3, [1,2,1,2]*2].
Could you confirm this?

@junjun3518 Thank you very much. Checked it quickly, and seems like you are right, I am very sorry for that bug. I am planning to make a huge update of this repo to get better quality of generation, and this will be fixed.
