Colab doesn't save cycleGAN images correctly

[BRN]

Hi everyone,
I made an implementation of the cycleGAN model but I find a strange problem.
If I run the model with a PC supplied to the university it works, while on Colab, it saves me empty PNG files. Consider that I use a standard GPU on Colab.

This is my code to save the generated images

def save_generated(image_ds, label, generator_model, outputs_path):
    i =  1
    for img in image_ds:
        generated = generator_model(img, training = False)[0].numpy()
     
        generated = (generated * 127.5 + 127.5).astype(np.uint8)   # re-scale
        im = Image.fromarray(generated)
        im.save(f'{outputs_path}{str(label)}_fake_image_{str(i)}.png')
        i += 1

Some idea?

Thank you.

Are you using Google Colab? Are you sure the modules are updated? Google Colab is touchy with where files are saved. Make sure it's in the proper folder. Keep thinking of ways the two environments could be different and make the adjustments.
