# TOSA converter for TFLite

A tool to legalize TFLite FlatBuffer to TOSA MLIR Bytecode.


## Python wheel creation

To build the Python wheel Clang is required, the wheel can then be built using:

```console
pip install build
python -m build --wheel
```

The wheel should now be in the `dist` directory.


## Usage

```python
from tosa_converter_for_tflite import tflite_flatbuffer_to_tosa_mlir_bytecode

tflite_flatbuffer_to_tosa_mlir_bytecode("model_input.tflite", "model_output.tosa.mlirbc")
```

## Command-line Interface (CLI)

The `tosa-converter-for-tflite` CLI provides a simple way to convert `.tflite` models
into TOSA MLIR bytecode. It supports both file-based and stream-based workflows
for easy integration into toolchains or pipelines.

### Usage Examples

**Convert a `.tflite` file to a TOSA bytecode file:**

```bash
tosa-converter-for-tflite model.tflite -o out.tosa.mlirbc
```

**Read the model from `stdin` and write to a file:**

```bash
cat model.tflite | tosa-converter-for-tflite -o out.tosa.mlirbc
```

**Read from a file and write to `stdout`:**

```bash
tosa-converter-for-tflite model.tflite > out.tosa.mlirbc
```

**Fully stream the model through the CLI and into another tool:**

```bash
cat model.tflite | tosa-converter-for-tflite | <downstream-tool>
```

## Supported Platforms

This tool supports Linux and Windows(r) on x86_64 architectures.

## Versioning

This project uses Calendar Versioning ([CalVer](https://calver.org/)) in the format: `YYYY.0M.Micro`

- **YYYY** – 4-digit release year (e.g., 2025)
- **0M** – 2-digit Zero-padded release month (e.g., 07 for July)
- **Micro** – The third and usually final number in the version. Sometimes referred to as the "patch" segment.
