can this package support GAN right now?

[guchengxi1994]

i read the example codes but it seems only support object detection right now, so i am wondering can this package supports a GAN model ?

and i cannot run the example code on release mode, here is the report.

but on debug mode it is good.

Hi ^_^, I am also currently working on an app that requires GANs, were you able to run it using this plugin?

[guchengxi1994]

@NinaM31 I think maybe you can use native android or iOS and flutter channels to do GANs, here is an example https://github.com/guchengxi1994/pytorch-mobile-trial

Thanks a lot @guchengxi1994 !
