How do I do this? 

I saw your post saying that you can just pass java Objects to Python methods but this is not working for numpy arrays and TensorFlow tensors. The following, and various variation of this, is what I tried and to no avail.

```java
double[][] anchors = new double[][]{{0.57273, 0.677385}, {1.87446, 2.06253}, {3.33843, 5.47434}, {7.88282, 3.52778}, {9.77052, 9.16828}};
PyObject anchors_ = numpy.callAttr("array", anchors);

```

I also tried to use concatenate to create this but it does not work. This is because concatenate (and stack, etc.) require a sequence containing the *names* of the arrays to be passed as an argument and there does not seem to be a way to do that with Chaquopy in Java. 

Any advice?
