InvalidArgumentError with vit-base-patch16-224 model?
Hi. So I am using a  pretrained model based on google’s vit-base-patch16-224-in21k for a binary classification of images (human vs non human) .I am using Keras/tensorflow 2.6.0 API.here are some parts of my code.# Downloading the base model
base_model = TFViTModel.from_pretrained('google/vit-base-patch16-224-in21k')

# Flipping and rotating images
data_augmentation = keras.Sequential(
    [layers.RandomFlip("horizontal"), layers.RandomRotation(0.1),]
)
# Freeze base model
base_model.trainable = False
# Create new model
inputs = keras.Input(shape = (3, 224, 224))
x = data_augmentation(inputs)   # apply data augmentation

x = base_model(x, training=False)[0]
outputs = tf.keras.layers.Dense(1, activation='sigmoid')(x)


# model
model_vit = tf.keras.Model(inputs, outputs)
model_vit.compile(loss='binary_crossentropy',optimizer='adam', metrics=['accuracy'])

model_vit.summary()

Fine, another approach is to use generators and define the batch size manually:from tensorflow.keras.utils import Sequence
import numpy as np   

class DataGenerator(Sequence):
    def __init__(self, x_set, y_set, batch_size):
        self.x, self.y = x_set, y_set
        self.batch_size = batch_size

    def __len__(self):
        return int(np.ceil(len(self.x) / float(self.batch_size)))

    def __getitem__(self, idx):
        batch_x = self.x[idx * self.batch_size:(idx + 1) * self.batch_size]
        batch_y = self.y[idx * self.batch_size:(idx + 1) * self.batch_size]
        return batch_x, batch_y

train_gen = DataGenerator(X_train_images, y_train_labels, 16)
test_gen = DataGenerator(X_val_images, y_val_labels, 16)

history = model_vit.fit(train_gen,
                    epochs=6,
                    validation_data=test_gen)this gives the error relating to input shapes?Epoch 1/6

train_functionCan anyone explain to me what " input depth must be evenly divisible by filter depth: 224 vs 3" means for me and how to fix?the shapes of my train and validation data are as follows:Train: X_train_images=(3932, 224, 224, 3), y_train_labels=(3932, 1)
Validation: X_val_images=(800, 224, 224, 3), y_val_labels=(800, 1)It is my first time experimenting with a ViT transfer model! thank you very much. Any other advice on my model architecture is welcome too.P.S. I have used this article as a guide to install hugging face and transformers through anaconda and run a model with my dataset of images,https://www.philschmid.de/image-classification-huggingface-transformers-keras

sayakpaul:Could you amend your code following this one?@sayakpaulHey, yes I can do it.I noticed 2 differences:You used TFData2VecVisionModel Instead of: TFAutoModelForImageClassificationYou added these lines to code:# Transpose because the `transformers` model has a leading channel dimension.
  dataset = dataset.map(lambda x, y: (tf.transpose(x, [0, 3, 1, 2]), y), AUTO)
  return dataset.prefetch(AUTO)I accept the first change.The second change - I faced some difficulty to aplly for my own dataset.I have dataset that I loaded with that code:data_dir = "/home/data/train"

dataflow_kwargs = dict(target_size=(IMAGE_SIZE,IMAGE_SIZE), batch_size=BATCH_SIZE,
                   interpolation="bicubic")
valid_datagen = tf.keras.preprocessing.image.ImageDataGenerator(
    **datagen_kwargs)
valid_generator = valid_datagen.flow_from_directory(
    data_dir, subset="validation", shuffle=True, **dataflow_kwargs)

I would suggest turning yourImageDataGeneratorinto atf.datapipeline.If you have numpy arrays then you can do something like the following:def pp(x, y):
    x = tf.transpose(x, [0, 3, 1, 2])
    return {"pixel_values": x, "labels": y}


tf_dataset = tf.data.Dataset.from_tensor_slices((x_train, y_train))
tf_dataset = tf_dataset.batch(BATCH_SIZE)
tf_dataset = tf_dataset.map(pp)The above assumes thatx_trainis a NumPy array consisting of the images andy_trainis a NumPy array consisting of the labels.

@sayakpaulI checked your example and the code in the github link.One thing that doesn’t address is, when augmenting, we don’t want to stick to one set of augmented data. The basic idea is the images are transformed in every epoch. If not, then the transformation as per your example is static and is similar to not applying any transformations.I am banging my head around for weeks now, trying to figure a way out. If only there is way to use huggingface model as as layer in a new model as you would normally do in case of keras (tensorflow) models.If you have any insights in that directions please help me out.Thanks.
