How do I install tensorflow and verify setup?

# Step 1: Set Up Your TensorFlow Environment Follow official pip installation for your OS (Linux/macOS/Windows/WSL2). ## Prerequisites - Python 3.9-3.12 - pip >=19.0 (Linux), >=20.3 (macOS) ## Quick Install (CPU) ```bash python3 -m venv tf_env source tf_env/bin/activate # Linux/macOS # or tf_env\Scripts\activate # Windows pip install --upgrade pip tensorflow ``` ## GPU (Linux/WSL2) ```bash pip install 'tensorflow[and-cuda]' ``` ## Verify ```python import tensorflow as tf print(tf.reduce_sum(tf.random.normal([1000, 1000]))) print(tf.config.list_physical_devices('GPU')) # If GPU ``` Use [Google Colab](https://colab.research.google.com) for no-install option. See full guide: https://www.tensorflow.org/install/pip

How do I complete quickstart: mnist digit classifier?

# Step 2: Hands-On Quickstart Tutorial Run the official beginner tutorial to classify handwritten digits. Open in [Colab](https://colab.research.google.com/github/tensorflow/docs/blob/master/site/en/tutorials/quickstart/beginner.ipynb) or locally. ## Key Code Steps ```python import tensorflow as tf # Load data mnist = tf.keras.datasets.mnist (x_train, y_train), (x_test, y_test) = mnist.load_data() x_train, x_test = x_train / 255.0, x_test / 255.0 # Build model tf.keras.models.Sequential([ tf.keras.layers.Flatten(input_shape=(28, 28)), tf.keras.layers.Dense(128, activation='relu'), tf.keras.layers.Dropout(0.2), tf.keras.layers.Dense(10) ]) # Compile & train model.compile(optimizer='adam', loss=tf.keras.losses.SparseCategoricalCrossentropy(from_logits=True), metrics=['accuracy']) model.fit(x_train, y_train, epochs=5) # Evaluate model.evaluate(x_test, y_test) ``` Expect ~98% accuracy.

How do I master core concepts: tensors & keras?

# Step 3: Dive into TensorFlow Fundamentals Read [TensorFlow Guide](https://www.tensorflow.org/guide) sections on tensors, eager execution, Keras. ## Practice Tensors ```python import tensorflow as tf t = tf.constant([[1., 2.], [3., 4.]]) print(t.shape, t.dtype) print(tf.add(t, t).numpy()) ``` ## Keras Basics - Sequential vs Functional API - Layers: Dense, Conv2D, etc. - Optimizers: Adam, SGD Experiment in Colab: modify quickstart model (add layers, change optimizer).

How do I build image classification model?

# Step 4: Train CNN on Fashion MNIST Extend to [Keras Classification Tutorial](https://www.tensorflow.org/tutorials/keras/classification). Key additions: - Use tf.keras.utils.to_categorical for one-hot - Add Conv2D layers: ```python model = tf.keras.Sequential([ tf.keras.layers.Flatten(input_shape=(28, 28)), tf.keras.layers.Dense(128, activation='relu'), tf.keras.layers.Dense(10, activation='softmax') ]) ``` Train, predict on new images. Explore [Image Tutorials](https://www.tensorflow.org/tutorials/images/cnn).

How do I project: transfer learning & deploy?

# Step 5: Real-World Project with Deployment Follow [Transfer Learning Tutorial](https://www.tensorflow.org/tutorials/images/transfer_learning). 1. Use pre-trained MobileNetV2 on cats/dogs. 2. Fine-tune top layers. 3. Export model: model.save('my_model') 4. Convert to TensorFlow Lite: https://www.tensorflow.org/lite Deploy: Run in browser with TF.js or serve with TensorFlow Serving. Build portfolio project: classify your images.

Step 1: Set Up Your TensorFlow Environment

Follow official pip installation for your OS (Linux/macOS/Windows/WSL2).

Prerequisites

Python 3.9-3.12
pip >=19.0 (Linux), >=20.3 (macOS)

Quick Install (CPU)

python3 -m venv tf_env
source tf_env/bin/activate  # Linux/macOS
# or tf_env\Scripts\activate  # Windows
pip install --upgrade pip
tensorflow

GPU (Linux/WSL2)

pip install 'tensorflow[and-cuda]'

Verify

import tensorflow as tf
print(tf.reduce_sum(tf.random.normal([1000, 1000])))
print(tf.config.list_physical_devices('GPU'))  # If GPU

Use Google Colab for no-install option.

See full guide: https://www.tensorflow.org/install/pip

Why this step matters:

-Builds a reliable environment for experimentation
-Prevents compatibility issues in real ML projects

30-60 minutes

Python 3.9+, pip, venv or Conda, Google Colab

Definition of Done

•Successfully imports tensorflow as tf
•Verification script prints tensor sum without errors
•GPU devices listed if applicable

Common Mistakes to Avoid

❌ Installing without virtual environment

→Always use venv to isolate dependencies

❌ Using unsupported Python version

→Check python3 --version; use 3.9-3.12

❌ Skipping GPU driver check

→Run nvidia-smi before pip install tensorflow[and-cuda]
