You have to take in a pointer or make a custom codec |

So this works (and the implicit conversion operator does not work), but not very ideal from Pythom object memory pressure standpoint (it reallocates a Python array with Python number elements). If I remove the I wonder if there is a way to obtain a |

I think I'm approaching a zero-copy solution. Would you have an advice of how to call an implicit conversion operator from Python? E.g. I have a |

Okay, figured it out by doing the implicit conversion in C#. Please find the complete example in https://gist.github.com/vadimkantorov/c9ab97aff995ea01ea7f6248ddc733bc#file-csharpfrompython-cs-L23-L41 :) I think I wouldn't need a Codec impl, but if anyone is looking for this, my example should help! The zero-copy impl requires unsafe compilation though. It would also be nice if there existed a natively supported way of converting a NumPy dense tensor to a rectangular C# array, currently this hits |

I have a method in C# which accepts an argument of type
ReadOnlyMemory<float>.How can I call this method from Python (using PythonNet) and pass / marshall a NumPy array (of dtype np.float32)? (need not necessarily a zero-copy way)
