Hello, please create tensor from NDArray in your case. For more information about how to create a tensor, you can refer to the source code.

I was writing unit tests around a method that takes a 1D Tensor then extracts each element from it (each one still as a Tensor) I think the code above fails because the Tensor has not yet been calculated in a graph.

If I make this replacement in the test above it then passes:

var tensor = tf.constant(elements);

@Wanglongzhi2001 your right constructing the Tensor from NDArray also works fine, thankyou.

	var raw_elements = new int[3]{1, 2 , 3};
        var elements = np.array(raw_elements);
        var tensor = new Tensor(elements);

I'll close the issue. What a great project. I'm finding using BARD rather than ChatGPT to help with coding works better as the code examples it generates are more up to date.
