Chore_26_compare-layer-import-export-onnx

Context

• [Add 🚀] necessary functions to easily create many unit-tests to try import/forward_dims/export of Aidge operators copying ONNX operators aidge_onnx#26
  • function to create an ONNX model containing a single operator to test (any opset, any operator type).
  • Import the operator
    • update import function to copy input Tensor dimensions to Aidge model
  • Export the operator
    • update export function to copy input Tensor dimensions and run forward_dims() if necessary
• [Fix 🔥 🐛] Constant ONNX operator import in case of 0-dimension array aidge_onnx#29 (closed)
  • add binding for Tensor constructor from shape and dtype
  • add binding for Tensor constructor from single arithmetic value
• [Enhance ✨] GraphView.save() to show dimension of input Tensors if set

Modified files

• pybind_Tensor.cpp
• GraphView.cpp

Detailed major modifications

More constructors available in Python API for Tensor.
