Tensors.create factory method is not supported about java HOT 5 CLOSED

Just jumping into this ticket as well, so the proper way to create tensors now is by using factories exposed by the type themselves. Here's a few examples for 32-bit integer tensors:

Tensor<TInt32> scalar = TInt32.scalarOf(0);

Tensor<TInt32> array = TInt32.vectorOf(1, 2, 3, 4);

// this is efficient for large tensors, as it does not require to preallocate or 
// duplicate the whole data before feeding the tensor
Tensor<TInt32> matrix = TInt32.tensorOf(Shape.of(2, 4), data -> 

    // your input loop here, you could read from an `InputStream`, etc. but let's use
    // a simple case as an example
    data.set(NdArrays.vectorOf(1, 2, 3, 4), 0)
        .set(NdArrays.vectorOf(5, 6, 7, 8), 1)
); 

// this can be more convenient for small tensors, for the improved syntax
Tensor<TInt32> matrix3d = TInt32.tensorOf(StdArrays.ndCopyOf(new int[][][] {
  {
     {1, 2, 3}, {4, 5, 6}
  },
  {
     {7, 8, 9}, {10, 11, 12}
  }  
}));

// and more options...

You can do pretty much the same using the Constant for tensors with a fix value in a graph.

And finally, you can rely on the Tensor factories if you need better fine-tuning or selection of the datatype at runtime.

It depends what you are trying to do, but the Tensor infrastructure now creates tensors from NdArrays which are defined in tensorflow-tools. To use the old slow path you can create an NdArray using org.tensorflow.tools.ndarray.StdArrays, and then feed the resulting object into <Type>.tensorOf(), where is the type of Tensor you want to create (e.g. TFloat32, TInt32 etc). If your data isn't stored in a java multidimensional array then we recommend that you write it directly into an NdArray after allocating one of the appropriate size (using org.tensorflow.types.<type>.tensorOf(shape).

Thanks for reply!!
Can you please share what is alternative way?

from java.

Those methods are horribly inefficient due to the way Java multidimensional arrays are constructed, so they've been removed from the new API.

I'm too looking for some better alternative, any help would be great.
