python-kerasHow do I use Python and Keras to create a tutorial?

1. To create a tutorial with Python and Keras, you will need to install the packages first. You can do this using the pip install command in the terminal.
2. After the packages are installed, you will need to import the necessary modules. This can be done with the following code:

import keras
from keras.models import Sequential
from keras.layers import Dense

3. Next, you will need to define the model. This can be done with the following code:

model = Sequential()
model.add(Dense(units=64, activation='relu', input_dim=100))
model.add(Dense(units=10, activation='softmax'))

4. Once the model is defined, you can compile it with the following code:

model.compile(loss='categorical_crossentropy',
              optimizer='sgd',
              metrics=['accuracy'])

5. After the model is compiled, you can train it with the following code:

model.fit(x_train, y_train, epochs=5, batch_size=32)

6. Finally, you can evaluate the model with the following code:

loss_and_metrics = model.evaluate(x_test, y_test, batch_size=128)

7. Once the model is evaluated, you can use it to make predictions. This can be done with the following code:

classes = model.predict(x_test, batch_size=128)
