# AI use cases for Tren Torch (TrenTorch/TrenTorch)

Repo: [TrenTorch/TrenTorch](https://github.com/TrenTorch/TrenTorch) | Use cases: 3 | Page: https://dedupedai.com/use-cases/trentorch-trentorch/

TrenTorch is a learning platform for machine learning, with a from-scratch NumPy framework built in a terminal CLI and a browser site with hundreds of coding questions.

This file holds every use case of this repo. Each one starts with a "## " heading and ends with its URL.

## How to build a working ML framework from raw NumPy modules with Tren Torch

Repo: [TrenTorch/TrenTorch](https://github.com/TrenTorch/TrenTorch) | Difficulty: Intermediate | Time: 45 minutes | Basis: From the README

Work through 20 CLI modules that rebuild tensors, autograd, optimizers, and transformers.

**Who it is for:** A developer who uses PyTorch daily but wants to understand what loss.backward() actually does, and has a terminal and an afternoon.

**The problem:** Importing a framework hides how tensors, gradients, and training loops work, so debugging and design choices stay opaque.

**The outcome:** The learner has a local trentorch package built from their own solutions and has run the first module.

### Steps

1. `git clone https://github.com/TrenTorch/TrenTorch.git`
2. `cd TrenTorch/TrenTorch_CLI`
3. `python3 -m venv .venv && source .venv/bin/activate`
4. `pip install -r requirements.txt && pip install -e .`
5. `tren setup`
6. `tren module start 01`

### Prompt to paste into your agent

```text
Clone https://github.com/TrenTorch/TrenTorch, enter TrenTorch_CLI, create a virtualenv, install requirements and the package, run `tren setup`, then `tren module start 01`. Report the path of the generated notebook under data/modules and confirm that the stub file exists without any import of torch.
```

### Caveat

The README says the CLI track uses Python and a local virtualenv, and that the notebooks contain stubs you must solve yourself, so the first module will not run until you write your own code.

## How to solve ML coding questions in the browser with instant grading with Tren Torch

Repo: [TrenTorch/TrenTorch](https://github.com/TrenTorch/TrenTorch) | Difficulty: Beginner | Time: 15 minutes | Basis: From the README

Answer topic-based ML questions in Pyodide with no local install and get graded instantly.

**Who it is for:** A learner or interviewer prep candidate who wants to practice ML coding on any device without setting up Python.

**The problem:** Setting up a local environment to practice small ML coding tasks slows down daily practice.

**The outcome:** The user has submitted at least one question and seen it graded in the browser, with a Problem of the Day attempt if they choose.

### Steps

1. Open trentorch.com in a browser.
2. Sign in with GitHub, Google, or email.
3. Choose a topic area such as Inference or Vision and start a question.
4. Write your answer in the starter file and submit it to be graded.
5. Open the Problem of the Day to try the one new web question for that day.

### Prompt to paste into your agent

```text
Open trentorch.com, sign in, start one question from the Inference track, and report the question title, whether the grader returned pass or fail, and the first failing test name if any.
```

### Caveat

The README says the web questions are graded in Pyodide, so you should expect browser-specific behavior and no local debugging tools unless you run the repo locally.

## How to run the web question checks locally before a pull request with Tren Torch

Repo: [TrenTorch/TrenTorch](https://github.com/TrenTorch/TrenTorch) | Difficulty: Advanced | Time: 45 minutes | Basis: From the README

Install the web app and run the Pyodide check that tests every reference solution.

**Who it is for:** A contributor who has been assigned an issue and needs to confirm their question changes pass CI before opening a pull request.

**The problem:** Question content changes can break reference solutions or tests, and CI failures waste review time.

**The outcome:** The contributor has run the Pyodide check locally and knows whether all reference solutions still pass.

### Steps

1. `git clone https://github.com/TrenTorch/TrenTorch.git`
2. `cd TrenTorch/TrenTorch_Web` (inferred, check the README)
3. `npm install`
4. `npm run test:pyodide`
5. Read the contributing guide at TrenTorch_CLI/docs/CONTRIBUTING.md before opening a pull request.

### Prompt to paste into your agent

```text
In the TrenTorch repo, enter TrenTorch_Web, run `npm install` and `npm run test:pyodide`, then report the number of questions checked and any failing reference solutions by name. Verify the command exits with code 0 before claiming success.
```

### Caveat

The README asks contributors to open an issue first and to be assigned before starting work, so running this check on unassigned work may not lead to a merged pull request.
