mmcli

Command-line interface for tinyml-modelmaker.

mmcli is a self-contained native binary (macOS, Linux, Windows) that drives the tinyml-modelmaker training and compilation pipeline entirely from the command line — no YAML config file required (though one can optionally be used as a base).

It ships with 9 bundled example datasets covering all task types, so you can create a project and start training with a single command.

How it works

mmcli is a lightweight binary (~10 MB) that does not bundle tinyml_modelmaker, PyTorch, or TVM. Instead it:

Translates your CLI arguments into the config dict that tinyml_modelmaker expects
Writes a temporary YAML file
Calls $MMCLI_PYTHON run_tinyml_modelmaker.py <tempfile> as a subprocess

This means tinyml_modelmaker runs in your existing Python 3.10 environment with all its native dependencies (including MPS/Metal for macOS training).

Note on compilation: The TVM compiler backend (ti_mcu_nnc) currently ships Linux and Windows wheels only. The mmcli compile and mmcli run subcommands will work on Linux/Windows. On macOS you can use mmcli train to train with Metal/MPS, then transfer the resulting model.onnx to a Linux machine for compilation.

Setup

1. Install tinyml_modelmaker (Python 3.10 environment)

# Create and activate a Python 3.10 venv
python3.10 -m venv ~/.venv-tinyml
source ~/.venv-tinyml/bin/activate

# Install tinyml_modelmaker from the release tag
pip install "tinyml_modelmaker @ git+https://github.com/musicalplatypus/tinyml-tensorlab.git@PlatypusCLI_1.0.0_Release#subdirectory=tinyml-modelmaker"

2. Set the environment variable

Add to your ~/.zshrc (or ~/.bash_profile):

export MMCLI_PYTHON="$HOME/.venv-tinyml/bin/python"

3. Get the binary

Option A — Use the pre-built binary:

cp dist/mmcli /usr/local/bin/mmcli   # or anywhere on your PATH

Option B — Download from GitHub Releases:

Pre-built binaries for macOS (arm64), Linux (x86_64), and Windows (x86_64) are published automatically on the Releases page.

Option C — Build it yourself (requires any Python + PyInstaller in an active venv):

git clone --branch PlatypusCLI_1.0.0_Release https://github.com/musicalplatypus/tinyml-cli.git
cd tinyml-cli
source ~/.venv-ai/bin/activate        # any venv with PyInstaller
pip install pyinstaller -q
pip install -e .
bash build_macos.sh                   # macOS  → dist/mmcli
bash build_linux.sh                   # Linux  → dist/mmcli
powershell build_windows.ps1          # Windows → dist/mmcli.exe

Subcommands

`mmcli init` — create a project from an example dataset

Create a new project directory pre-populated with a dataset, ready for training.

mmcli init -t TASK --dataset DATASET_NAME -p PROJECT_DIR [-m MODULE]
mmcli init --list [-t TASK] [-m MODULE]

Flag	Short	Description
`--list`	`-l`	List available datasets (no extraction)
`--task`	`-t`	Task type (required for extraction)
`--dataset`		Name of the example dataset (required for extraction)
`--project`	`-p`	Path for the new project directory (required for extraction)

  -i ./data/my_project \
  --epochs 30 \
  --batch-size 256

`mmcli compile` — compile only

`mmcli run` — full pipeline

Train then compile. Accepts all flags from both train and compile.

mmcli run \

mmcli info -m timeseries                        # list task types
mmcli info -m timeseries -t arc_fault           # details for arc_fault
mmcli info -m timeseries -t arc_fault -d F28P55 # models for F28P55

Dry run — inspect the generated YAML without running anything

mmcli --dry-run train \
  -m timeseries -t generic_timeseries_classification \
  -d F28P55 -n CLS_1k_NPU -i ./data

Override a base YAML config

mmcli train --config examples/hello_world/config.yaml \
            --epochs 50 --device F29H85

Verbose output (shows subprocess command + debug logs)

mmcli --verbose train ...

Training report

Generate a self-contained HTML report with live-updating accuracy/loss charts and a heatmap confusion matrix:

mmcli train \
  -m timeseries \
  -t generic_timeseries_classification \
  -d F28P55 \
  -n CLS_1k_NPU \
  -i ./data/my_project \
  --report

The report is written to <project_dir>/run/report.html and auto-refreshes every 5 seconds while training is in progress. Once training completes, the auto-refresh is removed and the final report includes the confusion matrix and file-level classification summary (if available).

Neural Architecture Search (NAS)

Instead of picking a model from the catalog (-n), you can let NAS automatically discover an optimal architecture for your dataset. NAS is supported for classification tasks only (timeseries and vision).

When --nas is set, --model/-n becomes optional — a synthetic name like NAS_m is generated automatically.

Feature extraction with NAS

Important: For timeseries tasks, you must specify --feature-extraction with a preset that is appropriate for your dataset when using --nas.

With catalog models (-n), the feature extraction configuration is provided automatically by the model description. NAS has no catalog entry, so the pipeline does not know which feature extraction to apply. Without this flag, training will fail with "Not enough dimensions present" because the raw sensor data has not been transformed into the feature representation that the classification pipeline expects.

To see which feature extraction presets are available for your task:

mmcli info -m timeseries -t generic_timeseries_classification

Common presets for generic timeseries classification include:

Generic_256Input_FFTBIN_16Feature_8Frame
Generic_1024Input_FFTBIN_32Feature_32Frame

NAS flags

Flag	Description
`--nas SIZE`	Enable NAS with a model size preset: `s` (small), `m` (medium), `l` (large), `xl` (extra-large). Controls the search space complexity and resulting model size.
`--nas-epochs N`	NAS search epochs (default: 10). Higher values explore more architectures but take longer.
`--nas-optimize MODE`	Resource optimization target: `Memory` (fewer parameters, default) or `Compute` (fewer MACs, lower latency).
`--feature-extraction`	Feature extraction preset (required for timeseries NAS). Use `mmcli info` to list available presets.
