Welcome to the TensorFlow model definition tutorial! This guide will walk you through creating a basic neural network using TensorFlow, a popular machine learning framework. Let's get started!
Step-by-Step Guide
1. Install TensorFlow
Before you begin, make sure TensorFlow is installed in your environment:
pip install tensorflow
🧠 Tip: Use tensorflow
for CPU/GPU support, or tensorflow-cpu
if you don't need GPU acceleration.
2. Import Libraries
Start by importing TensorFlow and other necessary libraries:
import tensorflow as tf
from tensorflow.keras import layers, models
3. Define Model Architecture
Create a sequential model with dense layers:
model = models.Sequential([
layers.Dense(64, activation='relu', input_shape=(784,)),
layers.Dense(64, activation='relu'),
layers.Dense(10, activation='softmax')
])

4. Compile the Model
Specify the optimizer, loss function, and metrics:
model.compile(optimizer='adam',
loss='sparse_categorical_crossentropy',
metrics=['accuracy'])
5. Train the Model
Use the fit
method to train on your dataset:
model.fit(x_train, y_train, epochs=5)
📊 Check training progress with this visualization:
Save Your Model 📁
After training, save the model for later use:
model.save('my_model.h5')
