Missing libpng16

[TommyV6]

I`m trying to install fluxgym and got:
<<PINOKIO_SHELL>>eval "$(conda shell.bash hook)" && conda deactivate && conda deactivate && conda deactivate && conda activate base && source /mnt/ssd2tb/pinokio/api/fluxgym.git/env/bin/activate /mnt/ssd2tb/pinokio/api/fluxgym.git/env && python app.py

Traceback (most recent call last):

I got libpng16 in system but in version extra/libpng 1.6.44-1
in webui i see only ENOENT: no such file or directory, stat '/mnt/ssd2tb/pinokio/api/fluxgym.git/{{input.event[0]}}'
I`m runing up-to-date Arch.

Same problem on Ubuntu 22.04.5 LTS

I am getting the same, Ubuntu 22.04

I found a fix. if you are using pinokio with fluxgym and with forge, then pay attention to the library opencv_python

which is installed in both environments:

/home/YOUR_USER/ai/pinokio/api/fluxgym.git/env/ 

and in

/home/YOUR_USER/ai/pinokio/api/stable-diffusion-webui-forge.git/app/venv/ 

If we do

source bin/activate

In each of them and then

pip list | grep cv

then for fluxgym it will print

opencv-python             4.8.1.78
opencv-python-headless    4.10.0.84

If you do the same for stable-diffusion-webui-forge.git , it will print the same version - 4.10.0.84. In this library the required so file
libpng16-1bde1c40.so.16.43.0 is located.

So, the solution is to run the command

pip install opencv-python==4.10.0.84

in the gluxgym's environment, after which it starts working

For developers: it would be good if you explicitly set this version in the requirements.txt
