SteganoGAN version or git commit:pip install steganogan
Python version (output of python --version):3.7.3
Pip version (output of pip --version):19.0.3
PyTorch version (output of python -c "import torch; print(torch.__version__)"):1.0.0
Operating System:Windows

Description

I am not able to encode or decode images(format .png). Error encountered:

AttributeError: 'PngImageFile' object has no attribute '_PngImageFile__frame'

What I Did

Tried encoding and decoding both the ways mentioned in SteganoGAN github page
1.Using command line and 2.Python interaction

1.Using Command Line
steganogan encode path/to/cover/image.png "Message to hide"
steganogan decode path/to/generated/image.png

2.Python
>>> from steganogan import SteganoGAN
>>> steganogan = SteganoGAN.load('steganogan/pretrained/dense.steg')

>>>steganogan.encode('research/input.png', 'research/output.png', 'This is a super secret message!')

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "..\Python\Python37\lib\site-packages\steganogan\models.py", line 295, in encode
    cover = imread(cover, pilmode='RGB') / 127.5 - 1.0

Hello @SINDHUN97, we have made a new release that may solve the issue that you are facing.

Can you try to install it again and run the example in the README. If you are using pip make sure to use: pip install steganogan=0.1.3, this will install force to install the latest version. I would recommend you to use a new virtualenv this way it will install everything from scratch.

If your problem persists:

Make sure that your Pillow version is 6.2.2 (you can run pip install pillow==6.2.2).
Make sure that reedsolo version is 0.3 (you can run pip install reedsolo==0.3).

Let us know if you were able to solve it or not.

hello sir sir we train this model on DIV2k dataset on 100 epocs and encoding is also done perfectly but in decoding it says failed to find message why?
