Error in training

[lchunleo]

Hi

i trying to run the training but encountered issue in the following.

UnboundLocalError: local variable 'discriminator_loss' referenced before assignment when trying to print("discriminator_loss : %f" % discriminator_loss)

You still facing this issue?

You still facing this issue?

Thanks for checking. I managed to resolve the above issue due to some path issues.

I tried to perform the training on my own dataset on google colab but i am still unable to get it running. is it very resource intensive? i tried changing my batch size to almost the min but unable to do so. i resize my images to 384x384

--batch_size=2 --epochs=3 --number_of_images=805 --train_test_ratio=0.8

Hello I can run network,utils files with out any error but when I try to run my training model I am getting an error and I am not understanding how to give input directory and what modifications we have to made to make to give a dataset of images as input for training purpose. Can you please help me to run this code Error: usage: ipykernel_launcher.py [-h] [-i INPUT_DIR] [-o OUTPUT_DIR] [-m MODEL_SAVE_DIR] [-b BATCH_SIZE] [-e EPOCHS] [-n NUMBER_OF_IMAGES] [-r TRAIN_TEST_RATIO] ipykernel_launcher.py: error: unrecognized arguments: -f /root/.local/share/jupyter/runtime/kernel-e1242cbc-2f55-4f63-aae5-b18b2fbfa737.json An exception has occurred, use %tb to see the full traceback.

Please all, I need the code of implementation this part the part is

{The SRResNet networks were trained with a learning rate of 10−4 and 106 update iterations. We employed the trained MSE-based SRResNet network as initialization for the generator when training the actual GAN to avoid undesired local optima.{
