Error in showing opacity level of PSD file through changing alpha channel

Description

I'm trying to merge two PNG file into a PSD file, but the result showed that it failed to show the opacity attributes. I don't know if I failed to find a correct module to run this operation, or that I had inputed wrong attributes. If it's the case that I found a wrong module, can someone please show me the original source code that directly addresses alpha channels?

What I Did

import pytoshop
from pytoshop.user import nested_layers
from pytoshop import enums
import numpy as np
from scipy import misc #read png
from PIL import Image
import numpy as np

img2 = misc.imread('2.png') 
#print(img2)
print('img2:',img2.shape) 
img2_t = np.transpose(img2, (2, 0, 1)) 
#print(img2_t)
print('img2_t:',img2_t.shape) 
#img2_t = np.transpose(img2_t, (1, 2, 0))
#misc.imsave('2_t.png',img2_t)

img4 = misc.imread('4.png') 
#print(img4)
print('img4:',img4.shape)
img4_t = np.transpose(img4, (2, 0, 1)) 
#print(img4_t)
print('img4_t:',img4_t.shape) 
#img4_t = np.transpose(img4_t, (1, 2, 0))
#misc.imsave('4_t.png',img4_t)

new_layer = pytoshop.user.nested_layers.Image(
    name='2.png', 
    visible=True, 
    opacity=255,
    group_id=0,
    blend_mode= b'norm', 
    top=250, 
    left=250,
    #bottom=1000,
    #right=1000, 
    # channels=(3,1000,1000), 
    channels=img2_t, 
    metadata=None, 
    layer_color=7, 
    color_mode=3
)

new_layer2 = pytoshop.user.nested_layers.Image(
    name='4.png', 
    visible=True, 
    opacity=255,
    group_id=0,
    blend_mode= b'norm', 
    top=0, 
    left=0,
    #bottom=500,
    #right=500, 
    # channels=(3,1000,1000), 
    channels=img4_t, 
    metadata=None, 
    layer_color=7, 
    color_mode=3
)
lays = [new_layer,new_layer2]
new_psd = pytoshop.user.nested_layers.nested_layers_to_psd(lays, color_mode=3, version=1, compression=1, depth=8, vector_mask=False)
print('new_layer:',new_layer)
#print(dir(new_layer))
print('_________________________________')
#print(new_layer.name)
#print('---new_psd:---',type(new_psd))
# # new_psd = pytoshop.user.nested_layers.nested_layers_to_psd(new_layer, color_mode=3)
with open('newfile.psd', 'wb') as fd: 
    new_psd.write(fd)
