I have an image classification project. I would like to fit the model. However, I got error messages.
This is my code for fitting the model.
model.fit(x=train_batches,
steps_per_epoch=len(train_batches),
validation_data=valid_batches,
validation_steps=len(valid_batches),
epochs=10,
verbose=2
)
This is the error message:

Looking at the error message, you have 4 different classes in your data. However, the logits contain 2 values for each sample. You probably need to adjust the final layer of your network. The output layer should output a tensor of dimension [batch_size, num_classes], or namely [batch_size, 4] but you are outputting [batch_size, 2].

I keep getting a "graph execution error" The complete code is in the link if you'd like to see it. I don't really understand the error at all. I was trying to get the epochs running but instead, I get "1/30" and then it just stops. I checked my folders and it appears that I have all jpeg files. I'm in a corner I don't know what to do.

I am currently working on a deep learning project in the signal processing domain. The currently used loss function is the mean square error (MSE). However, it turns out that this loss function does not directly reflect my evaluation metric. Thus, I decide to use the alternative loss function, named Zero mean Normalization Cross-Correlation (ZNCC).
Note: I use TensorFlow 2.0 for this project
Here is my defined loss function.
def ZNCC(true, predict):
true = true.numpy()
predict = predict.numpy()
x_bar = np.average(true)
y_bar = np.average(predict)
u = true - x_bar
v = predict - y_bar
top = np.dot(u,v)
bottom = np.linalg.norm(u) * np.linalg.norm(v)
zncc = top/bottom
if zncc<0:
zncc = 0
return tf.convert_to_tensor(1-zncc)
Here is the compilation statement
model = MyModel()
model.compile(optimizer=tf.keras.optimizers.Adam(learning_rate=0.002,beta_1=0.99,beta_2=0.989,epsilon=1e-07), loss=ZNCC, run_eagerly=True)
And here is my model.fit() statement
history = model.fit(training_generator,
validation_data=validation_generator,
epochs=150,
callbacks=[tensorboard_callback, model_checkpoint_callback])
After I run the above cell, I run into this error.

Could anyone provide the reason for this error and the solution to fix it?
Much appreciated.
EDIT
I have tried to reimplement the loss function like so:
def ZNCC(true, predict):
x_bar = tf.math.reduce_mean(true)
y_bar = tf.math.reduce_mean(predict)
u = true - x_bar
v = predict - y_bar
print(x_bar)
print(y_bar)
print(u)
print(v)
u = tf.dtypes.cast(u, tf.float64)
v = tf.dtypes.cast(v, tf.float64)
top = tf.tensordot(u,v,1)
bottom = tf.norm(u) * tf.norm(v)
zncc = top/bottom
print(top)
print(bottom)
print(zncc)
zncc = tf.cond(tf.less(zncc,0),lambda: tf.dtypes.cast(0, tf.float64), lambda: zncc)
return 1-zncc
Then I have also try to evaluate the function like so:
x = tf.constant([1, 2, 3, 4, 5])
y = tf.constant([2,2,2,2,1])
ZNCC(x,y)
It return the result as follow as expected:
tf.Tensor(3, shape=(), dtype=int32)
tf.Tensor(1, shape=(), dtype=int32)
tf.Tensor([-2 -1 0 1 2], shape=(5,), dtype=int32)
tf.Tensor([1 1 1 1 0], shape=(5,), dtype=int32)
tf.Tensor(-2.0, shape=(), dtype=float64)
tf.Tensor(6.324555320336759, shape=(), dtype=float64)
tf.Tensor(-0.31622776601683794, shape=(), dtype=float64)
<tf.Tensor: shape=(), dtype=float64, numpy=1.0>
However, when I try to run it as loss function it give the following error:

I'm a beginner in the world of neural networks and I have a Fully-Convolutional Neural Network for segmentation.
The model's architecture is the following:
seg_model = Sequential()
seg_model.add(Conv2D(40, (3,3), input_shape=(16,16, 3), activation="relu", padding="same"))
seg_model.add(Conv2D(20, (3,3), activation="relu", padding="same"))
seg_model.add(Dropout(0.3))
seg_model.add(Conv2D(1, (3,3), activation="sigmoid", padding="same"))
seg_model.compile(optimizer="rmsprop", loss="binary_crossentropy", metrics=["accuracy", "mae"])
After I implemented the input generators for data augmentation and tried to train the model, received an InvalidArgumentError: Graph execution error.
How can I solve this problem?
Input generators:
seg_datagen_params = {
'rotation_range' : 90,
'horizontal_flip': True,
'vertical_flip': True,
'fill_mode': 'constant',
'zoom_range': 0.4
}
seg_datagen = ImageDataGenerator(**seg_datagen_params)
seg_train_input = seg_datagen.flow(x_seg_train, batch_size=64, seed=1)
seg_train_output = seg_datagen.flow(y_seg_train, batch_size=64, seed=1)
seg_val_input = seg_datagen.flow(x_seg_val, batch_size=64, seed=2)
seg_val_output = seg_datagen.flow(y_seg_val, batch_size=64, seed=2)
train_seg_generator = zip(seg_train_input, seg_train_output)
val_seg_generator = zip(seg_val_input, seg_val_output)
Model training for segmentation:
earlystopping_callback = tf.keras.callbacks.EarlyStopping(monitor='val_loss', patience=10)
history = seg_model.fit_generator(generator=train_seg_generator, validation_data=val_seg_generator, epochs=200, verbose=1, callbacks=[earlystopping_callback])
InvalidArgumentError: Graph execution error:

/usr/local/lib/python3.7/dist-packages/ipykernel_launcher.py:5: UserWarning: `Model.fit_generator` is deprecated and will be removed in a future version. Please use `Model.fit`, which supports generators.

If memory growth is enabled for a PhysicalDevice, the runtime initialization will not allocate all memory on the device. Memory growth cannot be configured on a PhysicalDevice with virtual devices configured.
For example:
import tensorflow as tf
physical_devices = tf.config.list_physical_devices('GPU')
try:
tf.config.experimental.set_memory_growth(physical_devices[0], True)
except:
# Invalid device or cannot modify virtual devices once initialized.
pass
