v1.5.0

onnxmltools version 1.5.0 is now available! This version features ONNX Opset 10 support and code coverage.

How do I use the latest onnxmltools package?

pip install onnxmltools --upgrade
python -c "import onnxmltools"

This package includes converters for LightGBM, CoreML, Spark ML, LibSVM, XGBoost, and wrappers for conversion from scikit-learn and Keras.

1.4 release

v1.4.1

Update __init__.py

v1.4.0 rc1 pre-release.

v1.4.0-rc1

upgrade package version for the release.

v1.3.2

with some new converters, xgboost, libsvm, and pyspark.
refactor onnxmltools structure by splitting keras and sklearn converters out.

The final release for onnxmltools 1.3

switch to the explicit padding if the input shape is available. (#198)

* switch to the explicit padding if the input shape is available.

* upgrade the version.

* fix for the nchw mode.

* output_padding could be None.

1.3.0-rc1

1. Multiple opset support: Enables user to generate model based on a specified ONNX opset
2. ONNX opset 8: Adds support for ONNX opset 8 in all converters
3. ONNX model optimization: Reduces redundant operators like transpose and identity in the converted model
4. Convert channel_last to channel_first: Enables converted model to run on WinML even if the original model is channel_last, since the WinML API only supports channel_first models
5. onnxruntime as backend test: Uses onnxruntime as the backend to test the converted model; improves code quality and compatibility between converters and the inference engine
6. Separate LightGBM from scikit-learn converter: Improves code organization
