About 'lycon' module

[Young-Zzz]

Hi,when I run the 'test_dnd_rgb.py',If I didn't set the Parameter:'--save images',I can ran the code.
However,if I set the Parameter,I met the error:

Traceback (most recent call last):
  File "/workspace/Cycle/test_dnd_rgb.py", line 66, in <module>
    lycon.save(args.result_dir + 'png/'+ filenames[batch][:-4] + '.png', denoised_img)
  File "/opt/conda/lib/python3.7/site-packages/lycon/core.py", line 24, in save
    _lycon.save(path, image, options)
SystemError: <built-in function save> returned a result with an error set

Can u tell me why? Is the error of the 'lycon' version?But I only can pip install the version==0.2.0,the other version can't be pip install.
