Practical overview
When it fits
Use it when learning TensorFlow 2 fundamentals or seeking an example-led explanation of a specific operation or programming pattern.
Who it is for
- Developers learning TensorFlow 2 through code examples.
- Machine-learning practitioners looking up TensorFlow behavior such as broadcasting, control flow or numerical stability.
- NumPy users exploring TensorFlow’s tensor operations and graph execution.
Documented uses
- Learn TensorFlow 2 basics through examples such as matrix multiplication and fitting a simple function.
- Understand broadcasting and overloaded operators when working with tensors.
- Study TensorFlow conditionals and loops, including their relationship to Python control flow.
- Explore Python operations for kernel prototyping and visualization.
- Consult a focused introduction to numerical stability in TensorFlow.
Requirements & limits
- The guide is organized as a sequence of fundamentals topics, so readers can follow it as a learning path or consult individual chapters.
- Examples include a small regression task using TensorFlow variables, an optimizer and a loss function.
- The README references installation instructions for TensorFlow 2.0 alpha; treat that pinned example as historical rather than current setup guidance.
- The repository identifies a separate v1 branch for the original TensorFlow 1.x guide.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Learn TensorFlow 2 basics with matrix multiplication
Follow the guide’s basic example to multiply random matrices and inspect the TensorFlow result.
Before you start
- Python with NumPy and TensorFlow available; the example imports both libraries.
Steps
Import NumPy and TensorFlow.
Create two random 10-by-10 matrices with TensorFlow.
Multiply them using
tf.matmul.Print the result, or call
.numpy()on the TensorFlow tensor to obtain a NumPy representation.
Expected outcome
A 10-by-10 TensorFlow matrix product that can be printed or converted to NumPy.
Guide limitations
- The README’s installation snippet specifies TensorFlow 2.0 alpha and refers readers to the official installation instructions; it does not establish compatibility with current releases.
- The example demonstrates matrix multiplication, not a broader model-training workflow.
Train a simple polynomial model in TensorFlow 2
Use the README’s example to estimate coefficients for a quadratic function from generated samples.
Before you start
- Python with NumPy and TensorFlow available.
- The example uses TensorFlow variables, the Adam optimizer, and generated training data.
Steps
Create a three-element trainable variable and an Adam optimizer with learning rate 0.1.
Define the polynomial model, its L2-based loss, and a data generator for samples from
5x² + 3.Define a training step that minimizes the loss with respect to the variable.
Run the training step 1,000 times and print the learned variable values.
Expected outcome
The example reports coefficient values relatively close to the target parameters after training.
Guide limitations
- The README presents an illustrative result rather than a guaranteed output.
- The example uses randomly generated data and does not document a test or validation procedure.
- The README describes
tf.functionas an optional decorator for graph conversion and efficiency, but does not require it for this example.
