Error when using pretrained model with mel-sepcs from "deepvoice3-pytorch"

Hey, when i try to synthesis wav from mel files , this error occurs:

python synthesis.py --conditional=./output_mel/0_mel.npy ./wavenet_premodel/20180510_mixture_lj_checkpoint_step000320000_ema.pth generated

The mel(.npy) files is the file generated from "deepvpice3-pytorch" project. I extract the mel-spec (don't use lws to synthesis wav in deepvoice3-pytorch) and want to synthesis with wavenet-vovoder. But this error occurs, can you help me this?

The follow info may be helpful .

ar = np.load(0_mel.npy)
ar.shape ==> (80,48)
