[FIXED] Convert a variable sized numpy array to Tensorflow Tensors

Issue

I am trying Tensorflow 2.0 alpha preview and was testing the Eager execution . My doubt is that if you have a numpy array of variable size in middle like

input.shape
(10,)

input[0].shape
(109, 16)

input[1].shape
(266, 16)

and so on for the rest of the array , how does one eagerly convert them to tensors.

when I try

tf.convert_to_tensor(input)

or

tf.Variable(input)

I get

ValueError: Failed to convert numpy ndarray to a Tensor (Unable to get element as bytes.).

Converting each sub-array works , but because the sub-array size isn't same , tf.stack doesn't work.

Any help or suggestions ?

Solution

This was happening to me in eager as well. Looking at the docs here , I ended up trying

tf.convert_to_tensor(input, dtype=tf.float32)

And that worked for me.
