onnxruntime-training package has been deprecated

[Rohan138]

The onnxruntime-training package is no longer published after ORT 1.19.2 (current release is ORT 1.22.0); also, it is not published for Python 3.12+. New users should probably build the onnxruntime-training package from scratch before installing torch-ort e.g. https://onnxruntime.ai/docs/build/training.html

ERROR: Cannot install torch-ort==0.0.10, torch-ort==1.11.0, torch-ort==1.11.1, torch-ort==1.12.0, torch-ort==1.13.1, torch-ort==1.14.0, torch-ort==1.15.0, torch-ort==1.16.0, torch-ort==1.17.0, torch-ort==1.18.0, torch-ort==1.19.1, torch-ort==1.19.2, torch-ort==1.8.1 and torch-ort==1.9.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    torch-ort 1.19.2 depends on onnxruntime-training>=1.7.0
    torch-ort 1.19.1 depends on onnxruntime-training>=1.7.0
    torch-ort 1.18.0 depends on onnxruntime-training>=1.7.0
    torch-ort 1.17.0 depends on onnxruntime-training>=1.7.0
    torch-ort 1.16.0 depends on onnxruntime-training>=1.7.0
    torch-ort 1.15.0 depends on onnxruntime-training>=1.7.0
    torch-ort 1.14.0 depends on onnxruntime-training>=1.7.0
    torch-ort 1.13.1 depends on onnxruntime-training>=1.7.0
    torch-ort 1.12.0 depends on onnxruntime-training>=1.7.0
    torch-ort 1.11.1 depends on onnxruntime-training>=1.7.0
    torch-ort 1.11.0 depends on onnxruntime-training>=1.7.0
    torch-ort 1.9.0 depends on onnxruntime-training>=1.7.0
    torch-ort 1.8.1 depends on onnxruntime-training>=1.7.0
    torch-ort 0.0.10 depends on onnxruntime-training>=1.7.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip to attempt to solve the dependency conflict
