@Mushrat_Jahan,

Welcome to the Tensorflow Forum!

Could you please share standalone code to debug the issue?

Thank you!

I was trying to fit the GAN model and faced an error. model fitting code is given below-

g_model = build_generator(latent_dim)

 #g_model.load_weights("/content/drive/MyDrive/Dataset orginial/output/output/g_model.h5")

d_model.summary()
g_model.summary()

gan = GAN(d_model, g_model, latent_dim)

bce_loss_fn = tf.keras.losses.BinaryCrossentropy(from_logits=True, label_smoothing=0.1)

gan.compile(d_optimizer, g_optimizer, bce_loss_fn)

It seems shape mismatch issue between the tensors and the batch in your code.

What is the shape of your input images? You need to ensure that the number of channels in the input tensor matches the number of channels in the batch.

Could you provide tf_dataset() implementation part?

Thank you!

Here is the shape of my image-

IMG_H = 224
IMG_W = 224
IMG_C = 1 ## Change this to 1 for grayscale.
w_init = tf.keras.initializers.RandomNormal(mean=0.0, stddev=0.02)

#tf_dataset part
def tf_dataset(images_path, batch_size):
dataset = tf.data.Dataset.from_tensor_slices(images_path)
dataset = dataset.shuffle(buffer_size=10240)
dataset = dataset.map(load_image, num_parallel_calls=tf.data.experimental.AUTOTUNE)
dataset = dataset.batch(batch_size)
dataset = dataset.prefetch(buffer_size=tf.data.experimental.AUTOTUNE)
return dataset

@Mushrat_Jahan,

It seems that model is expecting RGB image (224,224,3) but the input image are of grayscale (224,224,1). Please ensure the shape compatibility for the model to run.

Thank you!

I had the same issue, however the issue was fixed after I changed my TF version from 2.14.0 to 2.13.0.

i was facing the same error,check the units value and your classes.If your classes are two then the value must be 2 and same for other no of classes.

I have a similar issue but my images already have 3 channels.
Could someone help me with this error?
Following I added my model summary.

The same issue occurs at my end; if you resolve it, please let me know how to fix it.
