different spec_min and spec_max values

Bắt đầu với phép tính trong diffsinger_task.py và so sánh các giá trị mel của dataset_cls('train') với usr/config/popcs_ds_beta6.yaml. Truy vết cách dữ liệu huấn luyện và các giá trị cấu hình được tạo ra, sau đó ghi lại hoặc sửa nguồn gốc của sự sai lệch spec_min, đồng thời xác nhận hành vi của spec_max.

Hi,

I use the codes in diffsinger_task.py to calculate the spec_min and spec_max for popcs train set. But I got the different values from the usr/config/popcs_ds_beta6.yaml. Especially for spec_min, there is a big gap between the calculate value and popcs_ds_beta6.yaml.
Could you please help if I miss something in the calculation step?
Thank you very much.

The codes I used is:
def build_tts_model(self):
import torch
from tqdm import tqdm
v_min = torch.ones([80]) * 100
v_max = torch.ones([80]) * -100
for i, ds in enumerate(tqdm(self.dataset_cls('train'))):
v_max = torch.max(torch.max(ds['mel'].reshape(-1, 80), 0)[0], v_max)
v_min = torch.min(torch.min(ds['mel'].reshape(-1, 80), 0)[0], v_min)
if i % 100 == 0:
print(i, v_min, v_max)
print('final', v_min, v_max)

The outputs of spec_mix and spec_max by diffsinger_task.py are the followings:
